[0025] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Embodiment 1
[0026] like Figure 1 As shown, a polyquaternium salt product raw material dripping tank includes a shell 2 and a water receiving box 1 which is sleeved on the lower part of the shell 2. The shell 2 and the water receiving box 1 constitute a rectangular structure as a whole. Arc-shaped settings are arranged on both sides of the front of the dripping tank, which is more beautiful as a whole. During the use of the dripping tank, the internal components are prone to frost, and the water receiving box 1 is used to collect the generated condensed water.
[0027] Combination Figure 2 and Figure 6 As shown, a heat exchange chamber 21 and a heat dissipation chamber 22 are provided inside the shell 2. When viewed from the front, the heat exchange chamber 21 is located in front of the heat dissipation chamber 22. An opening is provided on the partition between the heat exchange chamber 21 and the heat dissipation chamber 22, and a semiconductor refrigeration sheet 5 is provided in the opening. A heat exchange plate 6 is provided inside the heat exchange chamber 21. A flow channel 61 is provided inside the heat exchange plate 6, that is, the material exchanges heat through the flow channel 61, and the flow channel 61 is distributed in an S shape. A heat sink 4 is provided inside the heat dissipation chamber 22. The heat sink 4 and the heat exchange plate 6 are both close to the semiconductor refrigeration sheet 5. If necessary, heat dissipation silicone grease needs to be applied on both sides of the semiconductor refrigeration sheet 5, that is, when the semiconductor refrigeration sheet 5 is powered on, the heat on the heat exchange plate 6 is transferred to the heat sink 4, so as to realize the cooling of the material passed into the flow channel 61. The heat sink 4 includes a bottom plate, one side of the bottom plate is in contact with the semiconductor refrigeration sheet 5, and the other side is horizontally provided with a plurality of thin plates.
[0028] like Figure 3 As shown, a drive motor 10 is disposed inside the heat dissipation chamber 22, and a cross-flow fan blade 9 is fixedly connected to the output end of the drive motor 10. When the drive motor 10 is started, the cross-flow fan blade 9 rotates, and air passes through the heat dissipation element 4, thereby taking away the heat thereon.
[0029] The four corners of the heat sink 4 are provided with fixing bolts 8, which penetrate the heat exchange plate 6. The fixing bolts 8 also penetrate the partition between the heat exchange chamber 21 and the heat dissipation chamber 22 to achieve fixation, while also ensuring the close fit between the heat sink 4, the heat exchange plate 6 and the semiconductor refrigeration plate 5.
[0030] Combination Figure 2 and Figure 5 As shown, heat dissipation holes 24 are provided on both sides of the shell 2, and the heat dissipation holes 24 are connected to the heat dissipation chamber 22. Driven by the cross-flow fan blades 9, the outside air passes through the heat dissipation holes 24 and enters the heat dissipation chamber 22, and then the air passes through the heat sink 4, and is finally sent out from the heat dissipation holes 24 on the other side, so as to realize air cooling of the heat sink 4.
[0031] Combination Figure 2 and Figure 3 In the implementation, the heat exchange plate 6 is fixedly connected with the discharge pipe 3 and the inlet pipe 7, and the two ends of the flow channel 61 are respectively connected to the discharge pipe 3 and the inlet pipe 7. The material enters from the inlet pipe 7 and is sent out from the discharge pipe 3. The discharge pipe 3 is used for material dripping. According to production needs, it can be connected to the pipeline used for dripping. It should be noted that the inlet pipe 7 is located above the discharge pipe 3.
[0032] like Figure 5 As shown, a pipe hole 25 is provided on the front of the shell 2, and the discharge pipe 3 and the inlet pipe 7 extend from the pipe hole 25 to facilitate the connection of the material pipeline.
[0033] Combination Figure 4 and Figure 5 As shown, a bayonet 23 is provided on the lower front portion of the shell 2, and a clip 11 is provided on the upper front portion of the water receiving box 1, and the clip 11 and the bayonet 23 cooperate with each other, and the front end of the clip 11 is wedge-shaped, which is convenient for the water receiving box 1 to be buckled on the shell 2, and a convex point 12 is provided on the back side of the water receiving box 1, and the convex point 12 cooperates with the preset opening inside the shell 2. The setting of the convex point 12 and the clip 11 enables the water receiving box 1 to be stably fixedly connected to the shell 2. When the water receiving box 1 needs to be removed, the clip 11 is pressed so that the front end of the clip 11 and the bayonet 23 are staggered, and the water receiving box 1 can be conveniently removed downwards.
[0034] Both sides of the upper end of the shell 2 are provided with fixing ears 26, and the upper part of the fixing ears 26 is provided with an opening, and related fixing parts, such as fixing bolts, are used to pass through the opening to fix the drip tank. Embodiment 2
[0035] Based on the first embodiment, the present embodiment also has the following scheme: a water curtain is arranged inside the heat dissipation chamber 22, and the water curtain is located between the heat dissipation element 4 and the cross-flow fan blades 9. At the same time, a water pump is also arranged inside the shell 2, and the input end of the water pump extends to the inside of the water receiving box 1, and the output end of the water pump is fixedly connected to the water curtain. It should be noted that an opening is arranged at the bottom of the heat dissipation chamber 22, and excess water falls into the water receiving box 1.
[0036] When the drip tank is in use, the water pump also works at the same time to pump the water in the water receiving box 1 onto the water curtain, thereby improving the heat dissipation effect and using the condensed water at the same time, reducing the frequency of removing the water receiving box 1 for cleaning.
