[0010] In use, high-pressure water enters from the high-pressure water inlet, and since the low-pressure water outlet, the high-pressure water inlet and the overflow mounting port are connected with each other, and the overflow mounting port is provided with an overflow valve, the high-pressure water is converted into low-pressure water, so that the water flowing out of the low-pressure water outlet is low-pressure water. Adjusting the valve core to have three state positions in the control channel correspondingly makes the cooling control structure be in three different states, i.e. high-pressure water outlet state, low-pressure water outlet state and closed state, i.e. to realize low-pressure water outlet or high-pressure water outlet, or to close the water outlet.

[0030] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting and the like should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0031] Referring to Figures 1 to 5 , a cooling control structure of the present application is embodied as follows:

[0032] In an embodiment, a cooling control structure includes a housing 100, a control assembly 300, and the purpose is to switch the direction of the cooling liquid of the high-pressure water inlet by automatic or manual control, so as to realize that a high-pressure cooling pump can meet the cooling demand of different processing areas with different pressures.

[0033] The housing 100 is provided with a control channel 110 extending upward and downward, the two ends of the control channel 110 are respectively a control end and a closed end, the closed end is provided with a first plug 170, the side wall of the control channel 110 is provided with a low-pressure water outlet 120, a high-pressure water outlet 130, a high-pressure water inlet 140 and an overflow mounting hole 150, the position of the low-pressure water outlet 120 is arranged above the high-pressure water inlet 140, the high-pressure water outlet 130 is arranged below the high-pressure water inlet 140, in some other embodiments, the position of the high-pressure water outlet 130 is arranged above the high-pressure water inlet 140, and the low-pressure water outlet 120 is arranged below the high-pressure water inlet 140, but the overflow mounting hole 150 and the low-pressure water outlet 120 are arranged on the same plane perpendicular to the axis extending upward and downward of the valve core 320, because the overflow mounting hole 150 is provided with an overflow valve 200, the high-pressure water is discharged through the overflow valve 200, and the liquid flowing out of the low-pressure water outlet 120 is low-pressure liquid.

[0034] The control component 300 includes a valve core 320 and a drive mechanism 310. The drive mechanism 310 is provided with a drive end that is pulsatorically connected to the valve core 320 and drives the valve core 320 to slide up and down relative to the housing 100. The valve core 320 is provided with a water-passing structure. The valve core 320 has three state positions in the control channel 110, including a first state position, a second state position, and a third state position. In the first state position, the water-passing structure in the valve core 320 connects the low-pressure outlet 120, the high-pressure inlet 140, and the overflow port 150 to each other. In the second state position, the water-passing structure in the valve core 320 connects the high-pressure outlet 130 and the high-pressure inlet 140 to each other. In the third state position, the valve core 320 disconnects the low-pressure outlet 120 and the high-pressure outlet 130. That is, the first state position is the low-pressure water outlet state; the second state position is the high-pressure water outlet state; and the third state position is the closed state.

[0035] In this embodiment, the water passage structure includes a water passage groove 321 provided on the outer peripheral wall of the valve core 320. The water passage groove 321 is an annular groove. The outer peripheral wall of the valve core 320 and the inner side wall of the control channel 110 form an annular water passage channel, which increases the water passage volume.

[0036] In some other embodiments, the water-passing groove 321 does not necessarily need to be arranged in a ring shape on the outer peripheral wall of the valve core 320. As long as the water-passing groove 321 moves to the position of the low-pressure outlet 120, the water-passing channel formed by the water-passing groove 321 and the side wall of the control channel 110 can connect the low-pressure outlet 120, the high-pressure inlet 140, and the overflow port 150, while simultaneously closing the high-pressure outlet 130 and the high-pressure inlet 140; and when the water-passing groove 321 moves to the position of the high-pressure outlet 130, the water-passing channel formed by the water-passing groove 321 and the side wall of the control channel 110 can connect the high-pressure outlet 130 and the high-pressure inlet 140, while simultaneously closing the low-pressure outlet 120, the high-pressure inlet 140, and the overflow port 150. Of course, if the water-passing groove 321 is not arranged in a ring shape, its water flow rate will be relatively small.

[0037] Furthermore, from Figures 1 to 3 It can be concluded that the low-pressure outlet 120 and the high-pressure outlet 130 are staggered on the vertical projection plane, and the water outlets of different pressures have different discharge directions. This means that not only can water of different pressures be discharged, but the discharge direction can also be switched, enabling a single high-pressure cooling pump to meet the cooling needs of different processing areas at different pressures. In some other embodiments, the low-pressure outlet 120 and the high-pressure outlet 130 are aligned on the vertical projection plane, meaning that liquids of different pressures can only be discharged to the same area.

[0038] When the driving mechanism 310 drives, the valve core 320 is above the control channel 110, the cooling control structure is in a low-pressure water outlet state, that is, the water passing groove 321 is connected with the low-pressure water outlet 120, the high-pressure water inlet 140 and the overflow installation port 150, and the connection between the high-pressure water outlet 130 and the high-pressure water inlet 140 is closed; when the valve core 320 is below the control channel 110, the cooling control structure is in a high-pressure water outlet state, that is, the water passing groove 321 and the water passing channel formed by the side wall of the control channel 110 can be connected with the high-pressure water outlet 130 and the high-pressure water inlet 140, and the low-pressure water outlet 120, the high-pressure water inlet 140 and the overflow installation port 150 are closed; or in a closed state, that is, the low-pressure water outlet 120 and the high-pressure water outlet 130 are closed. The driving mechanism 310 can be an oil cylinder, an air cylinder, a linear module or a screw mechanism. The driving mechanism 310 can automatically control the liquid outlet state of the cooling control structure. In other embodiments, a handle can be arranged on the valve core 320 to manually control the cooling control structure.

[0039] Further, the overflow valve 200 is provided with a valve outlet, the side wall of the control channel 110 is provided with a first overflow port 151, the shell 100 is provided with an overflow channel 160 extending upward and downward, the control channel 110 is connected to the overflow channel 160 and the first overflow port 151, the first overflow port 151 is arranged below the low-pressure water outlet 120 and the high-pressure water outlet 130, and the projection of the low-pressure water outlet 120 and the first overflow port 151 on the up-down direction is coincident, that is, the liquid outlet direction of the overflow liquid is consistent with the liquid outlet direction of the low-pressure water outlet 120. When the cooling control structure is applied to the metal cutting, machining and grinding process to cool and lubricate the tool and the workpiece, the controlled liquid is cutting fluid, and a water receiving tray is usually arranged below the workpiece to receive the cutting fluid. At this time, the low-pressure cutting fluid of the low-pressure water outlet 120 cools the workpiece, the liquid outlet direction of the overflow liquid is consistent with the liquid outlet direction of the low-pressure water outlet 120, the overflow liquid directly flows to the water receiving tray, that is, the overflow liquid and the low-pressure water flow to the same area, so that the overflow liquid can be easily collected without the need to set an overflow pipe. In other embodiments, the overflow channel 160 is connected to the valve outlet and the first overflow port 151, and the overflow liquid can be discharged through the first overflow port 151 and can be discharged through an external pipeline. Of course, the second overflow port 152 is also arranged in the embodiment, and the second overflow port 152 is provided with a second plug 161, and the overflow liquid can be discharged through an external pipeline when needed. Further, a plurality of second sealing rings 190 are arranged between the overflow installation port 150 and the overflow valve 200 to improve the sealing effect and prevent water leakage.

[0040] Further, the outer peripheral wall of the valve core 320 is provided with a sealing groove 322, the first sealing ring 180 is arranged in the sealing groove 322, the sealing groove 322 plays a role of fixing the first sealing ring 180, and since the first sealing ring 180 moves along with the valve core 320, it is also beneficial to facilitate the movement of the valve core 320 with the first sealing ring 180, neither hinders the movement of the valve core 320, nor is beneficial to sealing.

[0041] In other embodiments, with reference to Figure 4 and Figure 5 , the high and low pressure water outlet can be controlled by driving the valve core 320 to rotate around the axis extending upward and downward of the valve core 320, so as to realize that one high-pressure cooling pump can meet the cooling demand of different processing areas with different pressure. The rotation of the valve core 320 can be electric or manual. At this time, the low pressure water outlet 120 and the high pressure water outlet 130 are arranged on the same plane perpendicular to the axis extending upward and downward of the valve core 320, and the water passing groove 321 of the valve core 320 cannot be arranged in a ring shape, so as to partially pass water, resulting in small water passing channel and small water passing amount.

[0042] The preferred embodiments of the present application are specifically described above, but the present application is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
