Through temperature compensation, the electric heater heats the pipeline water flow by 10℃-15℃, which also solves the problem of low tap water temperature in winter leading to a decrease in water production of the reverse osmosis system; a new type of valve is used in the pipeline of the equipment to achieve a silent effect and solve the problem of high equipment noise.

[0017] 1. The present invention provides a water-making device for hemodialysis with a main unit capable of thermal disinfection. The device adopts a water purification mechanism, a cooling mechanism, a temperature insulation plate, a semiconductor refrigeration sheet, a coolant tank, a heat dissipation tower, a first heat dissipation fan, a mounting plate, a liquid separation plate, a circulating pump and a second heat dissipation fan. The coolant in the coolant tank is cooled by the semiconductor refrigeration sheet, and then the second heat dissipation fan blows through the liquid separation plate to generate cold wind that blows upward from the bottom, so that the cold wind blows through the entire water purification mechanism, thereby reducing the temperature generated when the water purification mechanism is in operation, allowing the water purification mechanism to operate for a long time and extending the service life of the water purification mechanism.

The device adopts a liquid separation plate, a heat dissipation tower, a shielding mechanism, a placement box, a dust collection plate, a rubber pad, and a buckle groove. The dust in the air passing through the device is isolated by the dust collection plate, so that the dust is prevented from adhering to the liquid separation plate and the heat dissipation tower, resulting in a decrease in the temperature conduction efficiency between the liquid separation plate and the heat dissipation tower and the air, thereby affecting the cooling effect of the cooling mechanism.

[0020] 4. The present invention provides a water-making device for hemodialysis whose main unit can be thermally disinfected. The device adopts a protective shell, a shock-absorbing mechanism, an upper fixing plate, a push rod, a sleeve rod, a spring and a lower fixing plate. The spring absorbs vibrations inside and outside the protective shell to maintain the stability of the protective shell, thereby preventing the device from moving randomly due to internal vibrations and affecting the surrounding environment.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1 , Figure 2 As shown, a water-making device for hemodialysis with a main unit capable of thermal disinfection comprises a protective shell 1, a ventilation valve 2 is movably installed on the upper side of the protective shell 1 near the right side, a water purification mechanism 3 is movably installed on the inner lower surface of the protective shell 1, a cooling mechanism 4 is fixedly sleeved on the inner side of the lower wall of the protective shell 1, a shielding mechanism 5 is fixedly connected to the outer wall of the protective shell 1 near the bottom, a shock absorbing mechanism 6 is fixedly connected to the lower surface of the protective shell 1, and ventilation holes 7 are provided on the left and right sides of the bottom wall of the protective shell 1.

[0031] It should be noted that the water purification mechanism 3 contains multiple water filtering components, such as precision filters, sand filters, carbon filters, softeners, etc., and also contains a thermal disinfection system to fully filter and purify the water passing through it. There are also multiple drain valves on it to detect the water quality after passing through each water filtering component.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the cooling mechanism 4 includes a thermal insulation plate 41, the outer wall of the thermal insulation plate 41 is fixedly connected to the middle part of the inner side of the bottom wall of the protective shell 1, a semiconductor refrigeration plate 42 is fixedly sleeved in the middle part of the thermal insulation plate 41, a coolant tank 43 is fixedly connected to the upper side of the semiconductor refrigeration plate 42, a heat dissipation tower 44 is fixedly connected to the lower side of the coolant tank 43, and a first heat dissipation fan 45 is fixedly connected to the lower side of the thermal insulation plate 41 near the left side.

[0033] It should be noted that when the semiconductor refrigeration chip 42 is powered on, its cold end is cooled down and its hot end is heated up. The semiconductor refrigeration chip 42 only cools down the coolant in the coolant tank 43. The heat dissipation tower 44 conducts the heat generated by the hot end of the semiconductor refrigeration chip 42 to expand the contact area between the hot end of the semiconductor refrigeration chip 42 and the air. The first heat dissipation fan 45 blows out air so that the hot end of the semiconductor refrigeration chip 42 can be cooled down quickly, so that the semiconductor refrigeration chip 42 can continue to cool the coolant in the coolant tank 43.

[0034] like Figure 4 , Figure 5 As shown, the upper side of the insulation plate 41 is fixedly connected to a mounting plate 46 via a convex column, and a plurality of evenly distributed liquid separation plates 47 are fixedly connected to the upper side of the insulation plate 41, and the liquid separation plates 47 are connected via circular tubes, and a circulating pump 48 is fixedly connected to the upper side of the insulation plate 41 near the front side, and the rear side of the circulating pump 48 is connected to the front side of the coolant tank 43 via a first pipe, and the front side of the circulating pump 48 and the front side of the liquid separation plate 47 located at the frontmost side, as well as the rear side of the coolant tank 43 and the rear side of the liquid separation plate 47 located at the rearmost side are connected via a second pipe, and two second cooling fans 49 symmetrically distributed on the left and right sides are fixedly connected to the inner upper surface of the bottom wall of the protective housing 1 near the left and right sides.

[0035] It should be noted that a vent is provided in the middle of the bottom wall of the protective shell 1, and the circulating pump 48 brings the coolant in the coolant tank 43 to each separator plate 47. The separator plate 47 is used to increase the contact area between the coolant and the air. The second cooling fan 49 is operated to allow air to pass through the separator plate 47, so that the coolant quickly cools the air and blows the cold air vertically from the lower side to the inner side of the protective shell 1.

[0036] like Figure 3 As shown, a heat-insulating layer 410 is fixedly sleeved on the inner side of the side wall of the protective shell 1 .

[0037] It should be noted that the thermal insulation layer 410 is used to isolate the internal and external environments of the protective shell 1 so that the heat between the internal and external sides of the protective shell 1 cannot be transferred to each other.

[0038] like Figure 2 , Figure 3As shown, the shielding mechanism 5 includes a placement box 51, and one side of the placement box 51 close to the insulation plate 41 is fixedly connected to the left and right sides of the outer side of the protective shell 1 near the bottom, and two placement boxes 51 are symmetrically distributed on the left and right sides, and the inner sides of the two placement boxes 51 are movably sleeved with dust collection plates 52.

[0039] It should be noted that the dust collecting plate 52 is used to absorb dust in the air passing through it to prevent the dust from entering the bottom wall of the protective housing 1 .

[0040] like Figure 3 As shown, a rubber pad 53 is fixedly connected to the inner side of the two placement boxes 51 away from the insulation board 41 .

[0041] It should be noted that the rubber pad 53 pushes the dust collecting plate 52 so that the dust collecting plate 52 is closely attached to the outer side of the protective shell 1, thereby avoiding a gap between the dust collecting plate 52 and the protective shell 1, allowing air to pass therethrough.

[0042] like Figure 3 As shown, buckle grooves 54 are provided at positions near the upper edges of the middle portions of the two placement boxes 51 that are away from each other.

[0043] It should be noted that the buckle groove 54 is used to facilitate pulling out the dust collecting plate 52 after the dust collecting plate 52 has absorbed dust to saturation, so as to replace the dust collecting plate 52 with a new one.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, the shock absorbing mechanism 6 includes an upper fixed plate 61, the upper side of the upper fixed plate 61 is fixedly connected to the lower surface of the protective shell 1 near the edge, the lower side of the upper fixed plate 61 is fixedly connected to a plurality of annularly distributed top rods 62, the outer sides of the plurality of top rods 62 are movably sleeved with sleeve rods 63, the lower ends of the plurality of top rods 62 are fixedly connected to springs 64, the lower side of the spring 64 is fixedly connected to the inner lower surface of the sleeve rod 63, and the lower surface of the sleeve rod 63 is fixedly connected to a lower fixed plate 65.

[0045] It should be noted that the spring 64 contains a damping component, and the spring 64 is used to absorb the force exerted on the device due to the vibration generated outside the device itself.

[0046] The working principle of the present invention is as follows: first, when the semiconductor refrigeration chip 42 is powered on, its cold end is cooled down and its hot end is heated up. Only the semiconductor refrigeration chip 42 cools down the coolant in the coolant tank 43. The heat dissipation tower 44 conducts the heat generated by the hot end of the semiconductor refrigeration chip 42 to expand the contact area between the hot end of the semiconductor refrigeration chip 42 and the air. The first heat dissipation fan 45 blows out air so that the hot end of the semiconductor refrigeration chip 42 can be cooled down quickly, so that the semiconductor refrigeration chip 42 can continuously cool down the coolant in the coolant tank 43. A vent hole is provided in the middle of the bottom wall of the protective housing 1. The circulating pump 48 brings the coolant in the coolant tank 43 to each liquid separation plate 47. The liquid separation plate 47 is used to increase the cooling The contact knots between the cooling liquid and the air, the operation of the second cooling fan 49 allows the air to pass through the liquid separator 47, so that the cooling liquid quickly cools the air, and the cold air is blown from the inner side of the lower vertical protective shell 1, and the cooling liquid in the cooling liquid tank 43 is cooled through the semiconductor refrigeration plate 42, and then the second cooling fan 49 blows through the liquid separator 47 to generate cold wind that blows upward from the lower side, so that the cold wind blows through the entire water purification mechanism 3, reducing the temperature generated when the water purification mechanism 3 is in operation, so that the water purification mechanism 3 can operate for a long time and extend the service life of the water purification mechanism 3. Secondly, the thermal insulation layer 410 is used to isolate the internal and external environments of the protective shell 1, so that the heat on the inner and outer sides of the protective shell 1 cannot be transferred to each other, and the thermal insulation layer 410 is used to isolate the internal and external environments of the protective shell 1, so that the heat on the inner and outer sides of the protective shell 1 cannot be transferred to each other. 0 protects the inside of the protective shell 1 to prevent the heat inside and outside the protective shell 1 from being transferred to each other, causing the cold air generated by the cooling mechanism 4 to be heated by the high temperature environment outside, causing the cooling effect of the cooling mechanism 4 on the water purification mechanism 3 to be greatly reduced. Then, the dust collecting plate 52 is used to absorb dust in the air passing through it to prevent dust from entering the bottom wall of the protective shell 1. The buckle groove 54 is used to facilitate the dust collecting plate 52 to be pulled out after the dust collecting plate 52 has absorbed dust to saturation, so as to replace the new dust collecting plate 52. The rubber pad 53 pushes the dust collecting plate 52, so that the dust collecting plate 52 is close to the outside of the protective shell 1, avoiding the existence of a gap between the dust collecting plate 52 and the protective shell 1, allowing air to pass through here, Through the isolation of the dust absorption plate 52, the dust in the air passing through it is adsorbed to prevent the dust from adhering to the separator plate 47 and the heat dissipation tower 44, resulting in a decrease in the temperature conduction efficiency between the separator plate 47 and the heat dissipation tower 44 and the air, affecting the cooling effect of the cooling mechanism 4. Finally, the spring 64 contains a damping component, and the spring 64 is used to absorb the force exerted on the device by the vibration generated by the device itself from the outside. The protective shell, shock absorbing mechanism, upper fixed plate, push rod, sleeve rod, spring and lower fixed plate are coordinated to absorb the vibration exerted on the inside and outside of the protective shell 1 through the spring 64, so as to keep the protective shell 1 stable and prevent the device from moving randomly due to internal vibration and affecting the surrounding environment.
