[0029] The reference numerals in the accompanying drawings include: outer medicine tube 1, first medicine inlet 101, first connector 102, inner medicine tube 2, second medicine inlet 201, second connector 202, overflow chamber 3, second medicine inlet tube 4, medicine outlet head 5, control valve 501, first connection part 502, mixing section 503, mixing hole 5031, second connection part 504, outflow section 505, outflow port 506, spiral nozzle 507, dosing box 6, collection trough 601, protective part 602, confluence trough 603, overflow trough 604, and medicine outlet 605.

[0030] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0031] This invention provides a uniform dosing device, such as... Figures 1 to 5 As shown.

[0032] In an exemplary embodiment, the uniform dosing device includes: an outer dosing tube 1, an inner dosing tube 2, and a dosing head 5. The outer dosing tube 1 is sleeved outside the inner dosing tube 2. A second connector 202 is provided at the end of the inner dosing tube 2 away from the dosing inlet, and a first connector 102 is provided at the end of the outer dosing tube 1 away from the dosing inlet.

[0033] The dispensing head 5 includes a control valve 501, a first connecting part 502, a mixing section 503, a second connecting part 504, and an outlet section 505 arranged sequentially along the same axis. The first connecting part 502 is used to connect with the second connector 202, and the second connecting part 504 is used to connect with the first connector 102. The diameter of the second connecting part 504 is larger than the diameter of the first connecting part 502. The mixing section 503 is located between the first connecting part 502 and the second connecting part 504. A mixing hole 5031 is provided on the side wall of the mixing section 503 to allow the liquid medicine in the external medicine tube 1 to enter the dispensing head 5.

[0034] In this embodiment, the uniform dosing device can be used alone for adding a single liquid or a mixture of liquids. In this case, dosing can be done solely through the inlet of the outer dosing tube 1 or solely through the inlet of the inner dosing tube 2. When two liquids or two mixtures need to be mixed, one liquid or mixture is added through the outer dosing tube 1, and the other liquid or mixture is added through the inner dosing tube 2. After opening the control valve 501, the two liquids or mixtures can be mixed and flow out from the outlet 506 of the outlet section 505.

[0035] The first connecting part 502 is provided to connect the inner medicine tube 2 and the medicine outlet 5, the second connecting part 504 is provided to connect the outer medicine tube 1 and the medicine outlet 5, and the mixing hole 5031 is provided to allow the medicine in the outer medicine tube 1 to enter the mixing section 503, so that the medicine is mixed under the action of flow and goes out from the outlet 506 together with the medicine in the inner medicine tube 2.

[0036] In one exemplary embodiment, the diameter of the mixing section 503 increases linearly from the first connecting portion 502 to the second connecting portion 504.

[0037] For example, the mixing section 503 is an inclined conical surface to facilitate the entry of the liquid medicine in the outer medicine tube 1.

[0038] In one exemplary embodiment, the diameter of the outlet section 505 gradually decreases and then gradually increases from near the second connection portion 504 to away from the second connection portion 504.

[0039] It should be noted that the diameter of the outflow section 505 gradually decreases to increase the outlet water pressure. The diameter of the outflow section 505 gradually increases to facilitate the spraying of the liquid.

[0040] In one exemplary embodiment, the maximum diameter of the outflow section 505 is smaller than the diameter of the second connection portion 504.

[0041] In this embodiment, the maximum diameter of the outflow section 505 is smaller than the diameter of the second connection portion 504, so as to provide sufficient water pressure for the liquid to flow out.

[0042] In one exemplary embodiment, a hollowed-out spiral nozzle 507 is connected to the inner wall of the first connecting part 502, and a water outlet channel is provided on the axis of the spiral nozzle 507.

[0043] It should be noted that the spiral nozzle 507 is designed so that the liquid medicine in the inner medicine tube 2 can enter the mixing section 503 in a spiral shape, thereby mixing the liquid medicine in the outer medicine tube 1. The spiral nozzle 507 serves to improve the uniformity of the liquid medicine mixing. At the same time, if the liquid medicine in the inner medicine tube 2 is not mixed evenly, it can also be further mixed by the spiral nozzle 507.

[0044] In an exemplary embodiment, the top ends of the outer medicine tube 1 and the inner medicine tube 2 are medicine inlets, and the top end of the outer medicine tube 1 is higher than that of the inner medicine tube 2.

[0045] For example, the inlet of the inner drug tube 2 is called the first drug inlet 101, and the inlet of the outer drug tube 1 is called the second drug inlet 201.

[0046] In an exemplary embodiment, an overflow cavity 3 is provided at the end of the outer medicine tube 1 away from the medicine outlet 5. The top end of the overflow cavity 3 is connected to the medicine inlet at the end of the outer medicine tube 1. A second medicine inlet tube 4 is connected to the outer side wall of the overflow cavity 3. The inner medicine tube 2 passes through the top end of the overflow cavity 3 and is connected to the first medicine inlet tube.

[0047] It should be noted that, in order to avoid the fact that the liquid in the outer medicine tube 1 is only on the side near the second medicine inlet tube 4, which would affect the uniformity of the mixing after the liquid enters the mixing section 503, an overflow cavity 3 is provided. Only when the liquid level in the overflow cavity 3 reaches the height of the second medicine inlet 201 can it overflow from the second medicine inlet 201 into the outer medicine tube 1 in a spring-like manner.

[0048] In one exemplary embodiment, the inner wall of the first connector 102 is provided with an internal thread, and the second connecting part 504 is threadedly connected to the first connector 102.

[0049] In this embodiment, the outer medicine tube 1 and the medicine outlet head 5 are threaded together to ensure connection stability.

[0050] In one exemplary embodiment, the inner wall of the second connector 202 is provided with an internal thread, and the first connecting part 502 is threadedly connected to the second connector 202.

[0051] In this embodiment, the inner medicine tube 2 and the medicine outlet head 5 are threaded together to ensure connection stability.

[0052] In one exemplary embodiment, the uniform dosing device further includes a dosing box 6 for placing the desired dosing agent on it. The dosing box 6 has a plurality of collecting grooves 601 arranged side by side on one side surface near the dosing head 5. The collecting grooves 601 are separated by protective parts 602. The bottom end of the protective parts 602 is provided with a confluence groove 603 for communication between the collecting grooves 601. The top part of the protective parts 602 is provided with an overflow groove 604. The bottom surface of the dosing box 6 is provided with a dosing outlet 605, which is connected to the overflow groove 604.

[0053] It should be noted that existing dosing equipment typically has a dispensing pipe at the outlet of the mixed solution, with multiple dispensing holes on the pipe to ensure even distribution of the added solution in the storage box. However, a problem arises: the further the dispensing hole is from the outlet, the lower the hydraulic pressure and the smaller the outflow. In this solution, the inclusion of the collecting trough 601 prevents the solution from immediately reaching the item to be dosed after entering the dosing box 6. Instead, based on the fluidity of the liquid, the solution in the collecting trough 601 waits until it reaches the opening height of the overflow trough 604 before evenly overflowing from each overflow trough 604 into the item to be dosed, thus achieving uniform dosing.

[0054] It should also be noted that the overflow trough 604 is located on the side wall of the protective part 602, rather than on the surface of the protective part 602. The reason is that if it were located on the surface, when the medicine is added from above the dosing box 6, the medicine would directly exit through the overflow trough 604 and the outlet 605. However, by having the overflow trough 604 located on the side wall of the protective part 602, the above-mentioned problem would not exist.

[0055] For example, such as Figure 5 As shown, a protective groove is provided around the edge of the dosing box 6 for protecting the protective part 602, so as to prevent the liquid medicine coming down from above the dosing box 6 from flowing out of the dosing box 6 along the surface of the protective part 602.

[0056] It is worth noting that the overflow channel 604 must be located above the confluence channel 603, and the two do not intersect. The number, shape, and size of the overflow channels 604 and confluence channels 603 can be set according to requirements. The depth of the collection channel 601 can be set according to requirements.

[0057] In addition to the aforementioned uniform dosing equipment, this embodiment also provides a uniform dosing method, wherein if only one type of drug solution or a mixture of drug solutions needs to be added, the method includes the following steps:

[0058] Step S110: Place the dosing box 6 onto the item to be dosed.

[0059] Step S120: Add the medicine to the outer medicine tube 1 or the inner medicine tube 2. If it is added to the inner medicine tube 2, open the control valve 501.

[0060] If two or more solutions need to be added, the following steps are included:

[0061] Step S210: Place the dosing box 6 onto the item to be dosed.

[0062] Step S220: Add one type of liquid medicine or a mixture of liquid medicines to the inner medicine tube 2, and add another type of liquid medicine or a mixture of liquid medicines to the outer medicine tube 1. If the two types of liquid medicines or a mixture of liquid medicines need to be mixed before being added to the required medicine, open the control valve 501 to mix the liquid medicines in the inner medicine tube 2 and the outer medicine tube 1. If the two types of liquid medicines need to be added sequentially, put the liquid medicine to be added first into the outer medicine tube 1, and stop adding liquid medicine to the outer medicine tube 1 after the required amount of liquid medicine has been added. Then open the control valve 501 to allow the liquid medicine in the inner medicine tube 2 to enter the medicine outlet 5.

[0063] In summary, the above-mentioned uniform dosing equipment can be used for the sequential addition of multiple drug solutions, the individual addition of a single drug solution, and the mixing and addition of two drug solutions, making it highly versatile.

[0064] It should also be noted that, in order to avoid the accumulation of liquid in the overflow cavity 3 and the collection tank 601, a drain port can be opened at the bottom of the overflow cavity 3 and the collection tank 601, and a plug can be installed in the drain port. The plug can be opened during cleaning to drain the residual liquid inside.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
