[0032] The following further elaborates on the embodiments of the present utility model in conjunction with the accompanying drawings.

[0033] According to some embodiments of the present utility model, referring to Figures 1 to 4 , the anti-scalding device includes a housing 100 and a cooling water pipe 210. The housing 100 includes a first housing part 110 and a second housing part 120. The first housing part 110 and the second housing part 120 are integrally injection-molded. The first housing part 110 is horizontally arranged, the second housing part 120 is vertically arranged, and the upper end of the second housing part 120 is connected to the front end of the first housing part 110. The first housing part 110 is laid on the upper side of the melt pump 200, and the second housing part 120 is laid on the front side of the melt pump 200. The cooling water pipe 210 is located inside the housing 100 and abuts against the inner wall of the housing 100. The cooling water pipe 210 includes a plurality of pipe segments 211 formed by reciprocating bending. The plurality of pipe segments 211 are sequentially connected. The plurality of pipe segments 211 are respectively arranged inside the first housing part 110 and the second housing part 120. The pipe segments 211 located inside the first housing part 110 abut against the upper side wall and the lower side wall of the first housing part 110 at the same time, and the pipe segments 211 located inside the second housing part 120 abut against the front side wall and the rear side wall of the second housing part 120 at the same time. When the water flow in the cooling water pipe 210 passes through the first housing part 110 and the second housing part 120, it can dissipate heat.

[0034] It can be understood that when the melt pump 200 operates and generates heat, the heat is transferred to the first housing part 110 and the second housing part 120. The water in the cooling water pipe 210 can take away the heat of the first housing part 110 and the second housing part 120 during the flowing process, keeping the temperatures of the first housing part 110 and the second housing part 120 relatively low. The first housing part 110 is laid on the upper side of the melt pump 200 to prevent the upper side of the melt pump 200 from scalding the operator, and the second housing part 120 is laid on the front side of the melt pump 200 to prevent the front side of the melt pump 200 from scalding the operator.

[0035] Preferably, the water inlet end of the cooling water pipe 210 is connected to the tap water pipe, and the water outlet end is connected to other water-using devices to save water resources.

[0036] In some embodiments, referring to Figure 4 , both the left end and the right end of the housing 100 are open, that is, both the left and right sides of the first housing portion 110 and the second housing portion 120 are open, that is, the connection area between the side of the housing 100 close to the melt pump 200 and the side of the housing 100 far from the melt pump 200 is reduced to slow down the heat transfer. For example, the lower side surface of the first housing portion 110 is connected to the upper side surface of the first housing portion 110 through the rear side wall of the first housing portion 110, and both the left and right ends of the first housing portion 110 are open. While enhancing the heat dissipation efficiency of the inner cavity of the first housing portion 110, it slows down the heat transfer efficiency from the lower side surface of the first housing portion 110 to the upper side surface, ensuring that the temperature of the upper side surface of the first housing portion 110 that can come into contact with the operator is relatively low, avoiding scalding the operator. Similarly, the front side surface of the second housing portion 120 is connected to the rear side surface of the second housing portion 120 through the lower side wall of the second housing portion 120, and the temperature of the front side surface of the second housing portion 120 is lower than that of the rear side surface of the second housing portion 120, avoiding scalding the operator.

[0037] Preferably, referring to Figure 1 and Figure 2 , a temperature sensor probe 220 is provided on the upper side surface of the melt pump 200, and the first housing portion 110 is provided with a first through hole 141, and the temperature sensor probe 220 passes upward through the first through hole 141. It can be understood that first through holes 141 are provided on both the upper side surface and the lower side surface of the first housing portion 110 to communicate with the inner cavity of the housing 100, and the temperature sensor probe 220 passes through both first through holes 141 at the same time. The first through hole 141 can prevent the temperature sensor from colliding and interfering with the anti-scalding device, facilitating the connection of the temperature sensor probe 220 to other parts.

[0038] Preferably, referring to Figure 1 and Figure 2 , a first threaded hole is provided on the upper side surface of the melt pump 200, the first housing portion 110 is provided with a second through hole 142, and the anti-scalding device further includes a first bolt 230. The first bolt 230 passes through the second through hole 142 and is connected to the first threaded hole. The first bolt 230 presses the first housing portion 110 downward, making the first housing portion 110 relatively fixed to the melt pump 200, making the anti-scalding device relatively fixed to the melt pump 200, and preventing the anti-scalding device from falling off. It can be understood that second through holes 142 are provided on both the upper side surface and the lower side surface of the first housing portion 110 to communicate with the inner cavity of the housing 100. The first bolt 230 passes through both second through holes 142 from top to bottom at the same time, and the bolt head of the first bolt 230 presses downward on the upper side surface of the first housing portion 110.

[0039] Preferably, the housing 100 is filled with heat insulation cotton, and the gaps between adjacent pipe segments 211 and between the inner wall of the housing 100 and the pipe segments 211 are filled with heat insulation cotton, further slowing down the heat transfer to the upper side of the first housing part 110 and the front side of the second housing part 120, thereby preventing scalding the operator.

[0040] Preferably, referring to Figure 5 , a water inlet 161 is provided at the lower end of the second housing part 120, and a water outlet 162 is provided on the side of the first housing part 110 away from the second housing part 120. The cooling water pipe 210 passes through the water inlet 161 and the water outlet 162 respectively, and the water in the cooling water pipe 210 flows from the water inlet 161 to the water outlet 162. It can be understood that the heat on the upper side of the melt pump 200 is relatively high. When the melt pump 200 transfers heat to the housing 100, the temperature of the first housing part 110 is higher than that of the second housing part 120. The water in the cooling water pipe 210 first passes through the second housing part 120 to cool the second housing part 120, and then reaches the first housing part 110 to cool the first housing part 110, so as to make full use of water cooling and improve the cooling efficiency.

[0041] According to some embodiments of the present invention, referring to Figure 2 , Figure 4 and Figure 5 , the housing 100 further includes a third housing part 130. The third housing part 130 is horizontally arranged. The front end of the third housing part 130 is connected to the lower end of the second housing part 120. The upper side of the third housing part 130 is attached to the lower side of the melt pump 200. The third housing part 130 can prevent the operator from accidentally touching the lower side of the melt pump 200 and getting scalded. Preferably, referring to Figure 2 , a second threaded hole is provided on the lower side of the melt pump 200, and a third through hole 143 is provided on the third housing part 130. The anti-scalding device further includes a second bolt. The second bolt passes through the third through hole 143 and is connected to the second threaded hole. The second bolt presses the third housing part 130 upward, so that the third housing part 130 is relatively fixed to the melt pump 200. A plurality of pipe segments 211 are provided in the third housing part 130, and the water in the cooling water pipe 210 can take away the heat of the third housing part 130.

[0042] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the housing 100 is provided with a notch 150 to facilitate the handle of the melt pump 200 to pass through the notch 150 for the operator to use.

[0043] In the description of this specification, the description referring to the term "some embodiments" means that the specific features, structures, materials, or characteristics described in connection with that embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representation of the above term does not necessarily refer to the same embodiment or example.
