FIG. 2 is a top view of the water storage tank of the hydrogen generator;

FIG. 3 is an enlarged view of a portion of FIG. 1 at A;

in the figure: the hydrogen generator comprises a hydrogen generator water storage barrel 1, a mounting hole 11, air holes 12, a positioning mechanism 2, a fixing ring 21, an outer sleeve 22, an inner rod 23, a positioning column 24, a compression spring 25, a water supplementing barrel 3, a barrel body 31, a barrel opening 32, an annular groove 33, a sliding hole 34, a lifting rod 35, a push plate 36, a positioning groove 37, a positioning plate 38 and a sealing plate 39.

Detailed Description

As shown in fig. 1 to 3, an automatic water replenishing device for a VOC detector comprises a hydrogen generator water storage barrel 1, wherein at least one mounting hole 11 is formed in the hydrogen generator water storage barrel, a water replenishing barrel 3 is mounted in the mounting hole, the water replenishing barrel is inverted in the hydrogen generator water storage barrel, and a barrel opening 32 is deep below the liquid level of the hydrogen generator water storage barrel. According to the principle of torricelli,

when the liquid level of the water storage barrel of the hydrogen generator is lower than the barrel opening, the water in the water replenishing barrel flows into the water storage barrel of the hydrogen generator under the action of gravity, meanwhile, one bubble enters the water replenishing barrel to balance the external atmospheric pressure, when the barrel opening is submerged, the internal and external pressures are balanced again to finish a water replenishing action, and the circulation is carried out until the water in the water replenishing barrel is exhausted.

It is worth noting that the water replenishing barrel opening is sealed well, the water storage barrel is filled with enough water firstly, the barrel opening is just not on the liquid level, and the hydrogen generator is opened to normally operate.

In at least one embodiment, the upper surface of the water storage tank 1 of the hydrogen generator is provided with a plurality of air holes 12.

In at least one embodiment, the water replenishing barrel comprises a barrel body 31, a barrel opening 32 is arranged on the barrel body, a sliding hole 34 is arranged at the bottom of the barrel body, a lifting rod 35 is matched in the sliding hole in a sliding mode, a sealing plate 39 is connected to the bottom of the lifting rod, the sealing plate can be moved to the barrel opening under the driving of the lifting rod to seal the barrel opening, and the water leakage problem of the water replenishing barrel during handstand is avoided.

Further, the inner wall of the barrel body is provided with a positioning groove 37, the positioning groove is matched with a sealing plate, and the sealing plate can move into the positioning groove to seal the barrel opening, so that water is prevented from flowing out of the barrel opening.

In some embodiments, a positioning plate 38 is further disposed between the lifting rod and the closing plate, and the positioning plate can abut against the inner wall of the barrel body, so that secondary sealing of the opening of the barrel is achieved by means of the closing plate and the positioning plate.

And sealing rubber layers are arranged on the surfaces of the positioning plate and the sealing plate.

Further, a push plate 36 is mounted on the lifting rod.

In at least one embodiment, a positioning mechanism 2 is arranged on the inner wall of the water storage barrel of the hydrogen generator, and the positioning mechanism can enable the water replenishing barrel to be positioned in the mounting hole 11.

Specifically, positioning mechanism includes a solid fixed ring 21, gu fixed ring fixedly connected with outer tube 22, pole 23 in sliding fit has in the outer tube, interior pole tip installs reference column 24, the reference column can insert in the ring channel 33 of moisturizing cask outer wall, and the restriction moisturizing cask removes along the mounting hole.
