DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following further describes the present utility model with reference to the accompanying drawings.

[0027] As Figures 1 to 5 shown:

[0028] The present utility model is a water supply control device for laboratory use, including a support base 1 and a placement plate 2. The placement plate 2 is arranged above the support base 1. A water supply mechanism 3 is arranged on the tops of the support base 1 and the placement plate 2, and a support assembly 4 for improving the stability of the water supply device is arranged on the top of the placement plate 2;

[0029] The water supply mechanism 3 includes a heating device 301, a flask 302, a water bucket 303, a sealing cone 304, a water inlet pipe 305, a drain pipe 306, two hoses 307, two valves 308, a hollow pipe 309, a sliding rod 310 and a threaded cap 311. The heating device 301 is arranged on the top of the placement plate 2. The flask 302 is arranged on the top of the heating device 301. The water bucket 303 is arranged on the top of the support base 1. The sealing cone 304 is arranged on the top of the flask 302. The water inlet pipe 305 and the drain pipe 306 are both connected and arranged inside the sealing cone 304. One end of each of the two hoses 307 is respectively arranged on the water inlet pipe 305 and the drain pipe 306. The two valves 308 are respectively arranged outside the two hoses 307. The hollow pipe 309 is bolted to the top of the support base 1. The sliding rod 310 is bolted to the bottom of the placement plate 2. The threaded cap 311 is threadedly connected to the outside of the sliding rod 310. One end of the threaded cap 311 is threadedly connected to the outside of the hollow pipe 309. One end of the drain pipe 306 extends into the inside of the flask 302.

[0030] Specifically, as Figure 1 shown, a support plate 5 is bolted inside the support base 1. A rectangular plate 6 is slidably connected to the side wall of the support plate 5. A test tube groove 12 is formed at the top of the rectangular plate 6.

[0031] Specifically, as Figure 3 shown, a baffle 7 is bolted to one end of the support plate 5. A storage cavity 8 is formed between the baffle 7, the support base 1 and the support plate 5.

[0032] Specifically, as Figure 1 shown, support legs 9 for improving the stability of the support base 1 are bolted to the bottom of the support base 1. The number of the support legs 9 is four and they are evenly distributed.

[0033] Specifically, as Figure 1 shown, a protection part 10 for preventing the flask 302 from bursting and causing safety hazards is arranged on the top of the heating device 301.

[0034] Specifically, as Figure 1 shown, an anti-slip pad 11 for improving the anti-slip property of the support legs 9 is bolted to the bottom of the support legs 9. The anti-slip pad 11 is made of rubber material.

[0035] Specifically, as Figure 1 shown, anti-corrosion layers are sprayed on the tops of the support base 1 and the placement plate 2. The anti-corrosion layers are made of tetrafluoroethylene material.

[0036] During use, water is placed inside the flask 302 and the water bucket 303 respectively. Then, the heating device 301 heats the flask 302. At this time, the protection part 10 can provide protection for the flask 302 and prevent all the fragments from scattering when the flask 302 breaks. When the flask 302 is heated to an appropriate temperature, the air pressure inside the flask 302 increases, so that the heated water is pressed into the drain pipe 306 for laboratory use. At the same time, the water volume inside the flask 302 decreases, and the atmospheric pressure will decrease. At this time, the water inside the water bucket 303 will also enter the flask 302 through the hose 307 and the water inlet pipe 305 to continue heating for the next water supply. At the same time, the user can also place the test tube inside the test tube slot 12 for easy access. When water supply is not required, the heating device 301 can be turned off, then the valve 308 is closed, then the sealing cone 304 is removed, and then the threaded cover 311 is rotated to disengage the threaded cover 311 from the hollow pipe 309. Then, the placement plate 2 can be lifted upward, and the heating device 301 and the flask 302 on the top of the placement plate 2 are placed elsewhere to prevent laboratory personnel from contacting them and causing potential safety hazards.

[0037] Specifically, as Figure 3 and Figure 5 shown, the support assembly 4 includes a first connecting plate 401, a second connecting plate 402, a first fixing ring 403 and a second fixing ring 404. The first connecting plate 401 is bolted to the side wall of the placement plate 2, the second connecting plate 402 is bolted to the top of the placement plate 2, and the first fixing ring 403 and the second fixing ring 404 are respectively welded to one end of the first connecting plate 401 and the second connecting plate 402. The water inlet pipe 305 and the drain pipe 306 are respectively located inside the second connecting plate 402 and the first connecting plate 401 and are slidably connected.

[0038] When water enters or exits the flask 302, the water inlet pipe 305 and the drain pipe 306 may shake. At this time, the first fixing ring 403 and the second fixing ring 404 will limit the positions of the drain pipe 306 and the water inlet pipe 305 to improve the stability during water supply. Then, when the water inlet pipe 305 and the drain pipe 306 need to be stored, the first connecting plate 401 and the second connecting plate 402 can be disassembled.

[0039] By adopting the above technical solution, it solves the problem that in the prior art, when a water supply control device for a laboratory is in use, the placement rack is of an integral design. When the device is not in use, the integral placement rack will occupy a large space. When laboratory personnel accidentally touch the placement rack, the flask 302 on the placement rack will fall, resulting in potential safety hazards.

[0040] Working principle: During use, water is placed inside the flask 302 and the water bucket 303 respectively. Then, the heating device 301 heats the flask 302. At this time, the protection part 10 can provide protection for the flask 302 and at the same time prevent the fragments from scattering everywhere in case the flask 302 breaks. When the flask 302 is heated to an appropriate temperature, the air pressure inside the flask 302 increases, so that the heated water is pressed into the drain pipe 306 for use in the laboratory. At the same time, the water volume inside the flask 302 decreases, and the atmospheric pressure will decrease. At this time, the water inside the water bucket 303 will also enter the flask 302 through the hose 307 and the water inlet pipe 305, so as to continue heating for the next water supply. At the same time, the user can also place the test tube inside the test tube slot 12 for easy access. When water enters or exits the flask 302, the water inlet pipe 305 and the drain pipe 306 may shake. At this time, the first fixing ring 403 and the second fixing ring 404 will limit the positions of the drain pipe 306 and the water inlet pipe 305 to improve the stability during water supply. When water supply is not required, the heating device 301 can be turned off, then the valve 308 can be closed. Then, the sealing cone 304 is removed, and the threaded cap 311 is rotated to separate the threaded cap 311 from the hollow tube 309. Then, the placement plate 2 can be lifted upward, and the heating device 301 and the flask 302 on the top of the placement plate 2 can be placed elsewhere. Then, when it is necessary to store the water inlet pipe 305 and the drain pipe 306, the first connecting plate 401 and the second connecting plate 402 can be disassembled to prevent potential safety hazards caused by the contact of laboratory personnel with them.

[0041] The embodiments in the present utility model are only used to illustrate the present utility model and do not constitute a limitation to the scope of the claims. Other substantially equivalent alternatives that can be conceived by those skilled in the art are within the protection scope of the present utility model.
