[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] According to the prior art, the mixer needs to be cleaned after working for a long time and before mixing different types of materials. At this time, the upper shell needs to be removed from the lower shell, and then the upper shell and the lower shell need to be flushed through an external water pipe. Therefore, the mixer needs to be disassembled frequently, the cleaning process is relatively cumbersome, and the waste water generated during cleaning is not easy to collect.

[0022] Based on this, in order to make the cleaning operation of the mixer easier, the embodiments of the present application provide the following solution.

[0023] Please also read Figures 1 to 6, an embodiment of the present application provides a mixer that is easy to clean, a mixer that is easy to clean includes a bracket 1, a tank body 2, a mixing mechanism and a cleaning mechanism, the tank body 2 is inserted into the bracket 1, the mixing mechanism is arranged on the tank body 2 for stirring and mixing the materials inside the tank body 2, a feed pipe 21 and a discharge pipe 22 are arranged on the tank body 2, the cleaning mechanism includes a first water inlet pipe 41, a second water inlet pipe 42, a first water outlet pipe 43, a second water outlet pipe 44 and a valve assembly, the second water inlet pipe 42 is arranged on one end of the tank body 2 and is connected to the inside of the tank body 2, the first water outlet pipe 43 is arranged on the discharge pipe 22 and is connected to the discharge pipe 22, the valve assembly is used to connect the first water inlet pipe 41 and the second water inlet pipe 42, the first water outlet pipe 43 and the second water outlet pipe 44, and control their connection and disconnection, the first water inlet pipe 41 is used to connect to an external water source, and the second water outlet pipe 44 is used to discharge water flow to flush the inside of the tank body 2.

[0024] As can be seen from the above, when installing the mixer, the first water inlet pipe 41 can be connected to the external water source to facilitate subsequent cleaning operations. When it is necessary to clean the inside of the tank body 2, the feed pipe 21 and the discharge pipe 22 are closed, and the first water inlet pipe 41 is controlled to be connected to the second water inlet pipe 42 through the valve assembly, and the first water outlet pipe 43 is controlled to be disconnected from the second water outlet pipe 44. The water flow from the external water source flows through the first water inlet pipe 41 and the second water inlet pipe 42 and flows into the inside of the tank body 2. After the liquid level inside the tank body 2 reaches a certain height, the stirring mechanism is turned on and the first water outlet pipe 43 is controlled to be connected to the second water outlet pipe 44 through the valve assembly, and water flows continuously from the second water inlet pipe 42 to the inside of the tank body 2. Inside the tank body 2, the mixing mechanism will stir the water flow inside the tank body 2 to clean the inside of the tank body 2. The waste water enters the discharge pipe 22 and continuously flows out of the tank body 2 through the first water outlet pipe 43, and then is discharged to the outside of the tank body 2 through the second water outlet pipe 44. The staff can also connect the second water outlet pipe 44 with the external sewage pipe to discharge the waste water directly to the waste water collection point. After the cleaning is completed, the various parts of the cleaning mechanism can be controlled to return to the initial state through the valve assembly, so that the tank body 2 does not need to be disassembled during the cleaning process, and it is only necessary to control the external water source through the valve to flush the inside of the tank body 2 and discharge the waste water, which can make the cleaning operation of the mixer easier.

[0025] In some embodiments, please refer to Figures 1 to 4 The cleaning mechanism also includes a water pump 45, a first connecting pipe 46 and a second connecting pipe 47. The water pump 45 is arranged on an end of the tank body 2 away from the discharge pipe 22. One end of the first connecting pipe 46 is connected to the water outlet end of the water pump 45. The other end of the first connecting pipe 46 is connected to the first water inlet pipe 41 and the second water inlet pipe 42 through a valve assembly. One end of the second connecting pipe 47 is connected to the water inlet end of the water pump 45. The other end of the second connecting pipe 47 is connected to the first water outlet pipe 43 and the second water outlet pipe 44 through a valve assembly. The second connecting pipe 47 is provided with a filter assembly, and the filter assembly is used to filter out impurities in the water flow transported by the second connecting pipe 47 to the water pump 45 .

[0026] It is understood that the filter component allows water to flow through and can filter out impurities inside the water flow, and can be a filter screen, a filter plate, etc.; With such arrangement, during cleaning, the first water inlet pipe 41 is connected to the second water inlet pipe 42 through the valve assembly, and the first connecting pipe 46 is disconnected from the first water inlet pipe 41 and the second water inlet pipe 42, so that water flows continuously into the interior of the tank body 2. When the water level inside the tank body 2 reaches a certain height, the first water outlet pipe 43 is connected to the second water outlet pipe 44 through the valve assembly, and the second connecting pipe 47 is disconnected from the first water outlet pipe 43 and the second water outlet pipe 44. At this time, the water flows through the first water inlet pipe 41, the second water inlet pipe 42, the interior of the tank body 2, the first water outlet pipe 43, and the second water outlet pipe 44 in sequence, and the stirring assembly can be used to flow The water flow washes a large amount of impurities that are easier to wash away inside the tank body 2 to the outside of the tank body 2, and a small amount of impurities that are difficult to be washed away will remain inside the tank body 2; in actual application, the water pressure of the external water source and the thickness of each pipe can be changed to maintain the balance between the water flow into the tank body 2 and the water flow out of the tank body 2, so that the water level inside the tank body 2 is maintained at a suitable height; then the first water inlet pipe 41 is disconnected from the second water inlet pipe 42 and the first connecting pipe 46 through the valve assembly, and the second water inlet pipe 42 is connected to the first connecting pipe 46, and then the second water outlet pipe 44 is kept connected to the first water outlet pipe 43 and the second connecting pipe 47. The first water outlet pipe 43 and the second connecting pipe 47 are disconnected and the first water outlet pipe 43 and the second connecting pipe 47 are connected, and then the water pump 45 is started. The water pump 45 extracts the water flow inside the first water outlet pipe 43 and the second connecting pipe 47 and pumps it to the first connecting pipe 46 and the second water inlet pipe 42. At this time, the water flows through the second water inlet pipe 42, the inside of the tank body 2, the first water outlet pipe 43, the second connecting pipe 47, the filter component, the water pump 45, the first connecting pipe 46, and then returns to the second water inlet pipe 42, thereby forming a circulating filtration of the water flow. When the water flow passes through the filter component, the filter component removes the impurities carried inside the water flow, and the filtered clean water flows into the tank again. The inside of the tank body 2 is rinsed and the impurities inside the tank body 2 are washed away, so that the water resources can be reused while ensuring the cleaning efficiency of the inside of the tank body 2, thereby saving water; after a period of internal circulation cleaning, the cleaning mechanism is controlled by the valve assembly to perform external water flushing on the inside of the tank body 2, and all the waste water inside the tank body 2 is discharged with external water, and then the first water inlet pipe 41 is kept disconnected from the first connecting pipe 46 and the second water inlet pipe 42, so that the residual water inside the tank body 2 is discharged from the second water outlet pipe 44, and then the discharge pipe 22 is opened to discharge the small amount of residual water inside it.

[0027] Optionally, in some embodiments, referring to Figure 1 and Figure 8 The filter assembly includes a shell 61, a filter element 62 and an end cover 63. The shell 61 is provided with a water inlet 611 and a water outlet 612. The shell 61 divides the second connecting pipe 47 into two sections in the middle. The openings of the two sections of the second connecting pipe 47 are respectively connected to the water inlet 611 and the water outlet 612. The filter element 62 is slidably arranged inside the shell 61. The end cover 63 is threadedly connected to the opening of the shell 61 and abuts against one end of the filter element 62.

[0028] With such arrangement, when the tank body 2 is internally circulated and flushed, water flows from the water inlet 611 into the shell 61 under the action of the water pump 45, and then flows into the filter element 62. The filter element 62 filters out impurities in the water flow, and the filtered water flows out from the water outlet 612 and flows into the second connecting pipe 47 again. After the filter assembly has been working for a long time, the filter element 62 will no longer be able to effectively filter the water flow because too many impurities are adsorbed inside it. At this time, the end cover 63 can be unscrewed from the shell 61, and then the filter element 62 can be taken out of the shell 61 and a new filter element 62 can be placed into the shell 61, and then the end cover 63 can be screwed back to its original position to complete the replacement of the filter element 62, thereby ensuring that the filter assembly can work effectively for a long time.

[0029] Optionally, in some embodiments, see Figure 2 and Figure 5 The mixing mechanism includes a paddle 31, a rotating tube 32 and a power assembly. The rotating tube 32 is inserted into the tank body 2. One end of the rotating tube 32 is rotatably connected to an end of the tank body 2 close to the water pump 45. The other end of the rotating tube 32 is rotatably connected to an end of the tank body 2 away from the water pump 45. There are multiple paddles 31, which are all arranged inside the tank body 2 and fixedly connected to the outer peripheral surface of the rotating tube 32. The power assembly is used to provide power to rotate the rotating tube 32.

[0030] With such arrangement, when stirring the material inside the tank body 2 or cleaning the inside of the tank body 2, the power assembly is turned on to drive the rotating tube 32 to rotate, and the rotating tube 32 drives each blade 31 to stir the material or water flow inside the tank body 2, so that the material can be mixed evenly or the water flow can rinse the inside of the tank body 2 clean.

[0031] Optionally, in some embodiments, see Figures 1 to 4 The mixing mechanism further includes a third connecting pipe 34 and a fourth connecting pipe 35, one end of the third connecting pipe 34 is rotatably connected to an end of the rotating pipe 32 close to the water pump 45 through a rotating joint, the other end of the third connecting pipe 34 is connected to the first water inlet pipe 41 through a valve assembly, one end of the fourth connecting pipe 35 is rotatably connected to an end of the rotating pipe 32 away from the water pump 45 through a rotating joint, the other end of the fourth connecting pipe 35 is connected to the first water outlet pipe 43, and a two-way valve 351 is provided on the fourth connecting pipe 35 for controlling the connection and disconnection of the fourth connecting pipe 35; The cleaning mechanism also includes a spray cleaning component, which is arranged on the rotating tube 32 and can spray the top of the inner wall of the tank body 2.

[0032] It can be understood that the spray assembly can rotate with the rotating tube 32 and can extract the water flow inside the rotating tube 32 and spray it outward to flush the inside of the tank body 2. It can be a spray head or a self-powered water gun, etc.

[0033] With such arrangement, when cleaning the inside of the tank body 2, the water level inside the tank body 2 cannot be too high, otherwise it will affect the fluidity of the water flow inside the tank body 2, so that the mixing mechanism cannot fully stir the water flow, and the flushing effect of the water flow on the inner wall of the tank body 2 is reduced. Therefore, the top of the inner wall of the tank body 2 lacks the flushing of the water flow. After the mixer has been working for a long time, more impurities are easily adhered to the top of the inner wall of the tank body 2; when cleaning the mixer, after completing the internal circulation flushing, the first water inlet pipe 41 is disconnected from the first connecting pipe 46 and the second water inlet pipe 42 through the valve assembly, and the first water inlet pipe 41 is disconnected from the third connecting pipe 46. The connecting pipe 34 is connected, and then the two-way valve 351 is closed. At this time, water flows through the first water inlet pipe 41, the third connecting pipe 34, and the rotating pipe 32. The spray cleaning component can draw water from the rotating pipe 32 while rotating with the rotating pipe 32 and spray the top of the inner wall of the tank body 2, thereby washing away impurities adhering to the top of the inner wall of the tank body 2, thereby improving the cleaning effect of the cleaning mechanism on the inside of the tank body 2; after completing the cleaning of the top of the inner wall of the tank body 2, the first water inlet pipe 41 is disconnected from the third connecting pipe 34, and then the cleaning mechanism is controlled by the valve assembly to perform external water washing on the inside of the tank body 2.

[0034] Optionally, in some embodiments, see Figure 5 and Figure 7 The spray assembly includes two spray pipes 48, which are arranged inside the tank body 2. One end of the spray pipe 48 is connected to the rotating tube 32 and communicates with the inside of the rotating tube 32. Nozzles 481 are arranged on the outer circumferential surface of the spray pipe 48 and on the end of the spray pipe 48 away from the rotating tube 32.

[0035] With such arrangement, when cleaning the top of the inner wall of the tank body 2, the water flow inside the rotating tube 32 flows into the spray pipe 48 under the action of the water pressure of the external water source, and is then sprayed out through the nozzle 481. At the same time, the power component drives the rotating tube 32 to rotate, and the rotating tube 32 drives the spray pipe 48 and each spray head to rotate, so that various parts of the top of the inner wall of the tank body 2 can be flushed, thereby ensuring the flushing effect of the top of the inner wall of the tank body 2.

[0036] Optionally, in some embodiments, see Figure 5 The mixing mechanism further includes three scrapers 36 , each of which is disposed inside the tank body 2 , and one end of the scraper 36 is fixedly connected to the outer peripheral surface of the rotating tube 32 .

[0037] With such arrangement, when stirring the material inside the tank body 2, the scraper 36 can rotate with the rotating tube 32 and stir the material at the bottom of the tank body 2, reducing the stirring dead angle of the paddle 31 and improving the mixing effect of the mixer on the material; after the mixing of the material is completed, when the material needs to be discharged to the outside of the tank body 2, the discharge pipe 22 is opened and the power component continues to drive the stirring plate to rotate, and the material can continue to flow under the action of the stirring plate and be continuously discharged from the discharge pipe 22. Due to the poor fluidity of the material, when most of the material inside the tank body 2 is discharged, the remaining material will be piled at the bottom of the tank body 2 away from the discharge pipe 22. At this time, the scraper 36 can push the residual material at various places on the bottom of the tank body 2 and push it into the discharge pipe 22 to discharge it, thereby cleaning the residual material inside the tank body 2 and reducing the loss of the material; when cleaning the inside of the tank body 2, the scraper 36 can also scrape off the impurities adhering to the bottom of the tank body 2 so that they are washed away by the water flow, reducing the cleaning dead angle of the cleaning mechanism.

[0038] Optionally, in some embodiments, see Figures 1 to 4 The power assembly includes a motor 33, which is arranged on one end of the tank body 2 close to the feed pipe 21, and the output shaft of the motor 33 is connected to one end of the rotating tube 32 close to the water pump 45 through a belt and a pulley; The valve assembly includes a first three-way valve 51, a second three-way valve 52, a third three-way valve 53 and a fifth connecting pipe 54; one end of the first water inlet pipe 41, one end of the first connecting pipe 46 away from the water pump 45 and one end of the fifth connecting pipe 54 are respectively connected to the three interfaces of the first three-way valve 51; one end of the fifth connecting pipe 54 away from the first three-way valve 51, one end of the second water inlet pipe 42 away from the tank body 2 and one end of the fourth connecting pipe 35 away from the rotating tube 32 are respectively connected to the three interfaces of the second three-way valve 52; one end of the first water outlet pipe 43 away from the tank body 2, one end of the second water outlet pipe 44 and one end of the second connecting pipe 47 away from the water pump 45 are respectively connected to the three interfaces of the third three-way valve 53.

[0039] With such arrangement, the motor 33 can drive the rotating tube 32 to rotate through the belt and the pulley to complete various operations of the mixer; the first three-way valve 51, the second three-way valve 52, and the third three-way valve 53 are three-way semi-ball valves, and any two interfaces or three interfaces of the three-way valves can be connected, so that the valve assembly can complete the above-mentioned various operations; when flushing the top of the inner wall of the tank body 2, the first water inlet pipe 41 is connected to only one end of the fifth connecting pipe 54, and the other end of the fifth connecting pipe 54 is only connected to the third connecting pipe 34, and the water flows through the first water inlet pipe 41, the fifth connecting pipe 54, the third connecting pipe 34, and the rotating tube 32, thereby completing the flushing operation of the top of the inner wall of the tank body 2.

[0040] Optionally, in some embodiments, see Figure 5 and Figure 6 The tank body 2 is also provided with an end cover assembly, which includes a feed cover 71 and a discharge cover 72. The edge of the feed cover 71 is hinged on the feed pipe 21, and the edge of the feed cover 71 is also bolted to the feed pipe 21.
