The spiral spray head 507 plays a role of making the medicine mix more uniformly. In addition, if the mixed medicine in the inner medicine pipe 2 is not mixed uniformly, the spiral spray head 507 can be used to further mix the medicine.

[0039] In an example embodiment, the top ends of the outer medicine pipe 1 and the inner medicine pipe 2 are medicine inlet ports, and the top end of the outer medicine pipe 1 is higher than the top end of the inner medicine pipe 2.

[0040] For example, the medicine inlet port of the inner medicine pipe 2 is referred to as a first medicine inlet port 101, and the medicine inlet port of the outer medicine pipe 1 is referred to as a second medicine inlet port 201.

[0041] In an example embodiment, the outer medicine pipe 1 is provided with an overflow cavity 3 at an end away from the medicine outlet head 5, the top end of the overflow cavity 3 is in communication with the medicine inlet port of the end of the outer medicine pipe 1, the outer side wall of the overflow cavity 3 is provided with a second medicine inlet pipe 4 in communication therewith, and the inner medicine pipe 2 is provided with a first medicine inlet pipe connected through the top end of the overflow cavity 3.

[0042] It should be noted that, in order to avoid the situation that the liquid medicine is only present on the side close to the second medicine inlet pipe 4 in the outer medicine pipe 1, which affects the uniformity of the mixed liquid medicine after entering the medicine mixing section 503, the overflow cavity 3 is provided, and the liquid medicine in the overflow cavity 3 can only overflow to the outer medicine pipe 1 from the second medicine inlet port 201 in a gushing manner when the liquid level of the liquid medicine in the overflow cavity 3 reaches the height of the second medicine inlet port 201.

[0043] In an example embodiment, the inner wall of the first connector 102 is provided with an internal thread, and the second connecting part 504 is threadedly connected with the first connector 102.

[0044] In this embodiment, the outer medicine pipe 1 is threadedly connected with the medicine outlet head 5 to ensure the stability of the connection.

[0045] In an example embodiment, the inner wall of the second connector 202 is provided with an internal thread, and the first connecting part 502 is threadedly connected with the second connector 202.

[0046] In this embodiment, the inner medicine pipe 2 is threadedly connected with the medicine outlet head 5 to ensure the stability of the connection.

[0047] In an example embodiment, the uniform medicine adding device further comprises a medicine adding box 6 for being placed on a desired medicine adding object, and the side surface of the medicine adding box 6 close to the medicine outlet head 5 is provided with a plurality of flow collecting grooves 601 arranged side by side, the flow collecting grooves 601 are separated by protective parts 602, the bottom end of each protective part 602 is provided with a flow converging groove 603 for communication between the flow collecting grooves 601, and the top end of each protective part 602 is provided with an overflow groove 604; the bottom surface of the medicine adding box 6 is provided with a medicine outlet port 605 in communication with the overflow groove 604.

[0048] It should be noted that the existing dosing equipment, generally provided with a medicine outlet pipe on the outlet of the mixed liquid, and a plurality of medicine outlet holes are opened on the medicine outlet pipe to ensure the uniform distribution of the liquid medicine added into the liquid storage box. However, the problem is that the farther the medicine outlet hole is from the outlet, the smaller the liquid pressure and the outlet flow will be. In the present scheme, the opening of the flow collection groove 601 makes the liquid medicine entering the dosing box 6 not immediately added to the required article, but according to the fluidity of the liquid, the liquid medicine in the flow collection groove 601 needs to reach the opening height of the overflow groove 604, and then evenly overflow from each overflow groove 604 to the required article to be dosed, so as to realize uniform dosing.

[0049] It should be further pointed out that the overflow groove 604 is opened on the side wall of the protection part 602, rather than on the surface of the protection part 602, because if it is opened on the surface, the liquid medicine added from above the dosing box 6 will directly pass through the overflow groove 604 and the medicine outlet 605, and if the overflow groove 604 is opened on the side wall of the protection part 602, the above problem will not exist.

[0050] For example, as shown in Figure 5 As shown, a protection groove for protecting the protection part 602 is provided along the edge of the dosing box 6 to avoid the liquid medicine falling from above the dosing box 6 flowing out of the dosing box 6 along the surface of the protection part 602.

[0051] It is worth mentioning that the overflow groove 604 is necessarily opened above the flow collection groove 603, and the two do not intersect. The number and opening shape and size of the overflow groove 604 and the flow collection groove 603 can be set according to the requirements. The depth of the flow collection groove 601 can be set according to the requirements.

[0052] For the above-mentioned uniform dosing equipment, the present embodiment further provides a uniform dosing method, wherein if only one kind of liquid medicine or mixed liquid medicine needs to be added, the method comprises the following steps:

[0053] Step S110, placing the dosing box 6 on the required dosing article.

[0054] Step S120, adding liquid medicine into the outer medicine pipe 1 or the inner medicine pipe 2, and if added into the inner medicine pipe 2, opening the control valve 501.

[0055] If two kinds of liquid medicine or mixed liquid medicine need to be added, the method comprises the following steps:

[0056] Step S210, placing the dosing box 6 on the required dosing article.

[0057] Step S220, one liquid medicine or mixed liquid medicine is added into the inner medicine pipe 2, and another liquid medicine or mixed liquid medicine is added into the outer medicine pipe 1; if the two liquid medicines or the two mixed liquid medicines need to be mixed before being added to the required medicine adding article, the control valve 501 is opened, so that the liquid medicines in the inner medicine pipe 2 and the outer medicine pipe 1 are mixed; if the two liquid medicines need to be added in sequence, the liquid medicine which needs to be added first is put into the outer medicine pipe 1, and after the liquid medicine in the outer medicine pipe 1 is added to the required amount, the adding of the liquid medicine into the outer medicine pipe 1 is stopped, and then the control valve 501 is opened, so that the liquid medicine in the inner medicine pipe 2 enters the medicine outlet head 5.

[0058] In summary, the above-mentioned uniform medicine adding equipment can be used for the sequential addition of various liquid medicines, the separate addition of a single liquid medicine, and the mixed addition of two liquid medicines, and has strong applicability.

[0059] It should be further pointed out that, in order to avoid overflow in the overflow cavity 3 and the collection of liquid in the collection tank 601, a liquid discharge port can be provided at the bottom of the overflow cavity 3 and the collection tank 601, and a plug is arranged in the liquid discharge port. When cleaning, the plug is opened to discharge the residual liquid inside.
