The present utility model will be described in detail with reference to specific embodiments and drawings.

As shown in fig. 3 to 5, the insulation water tank 10 of the micro wet towel machine includes a tank body 100 and an openable water tank cover 200.

The tank 100 has a mouth 101, and the tank 100 includes an inner wall 102 and an outer wall 102 with a vacuum gap 103 maintained therebetween, thereby blocking the path of heat transfer from the stored water within the insulated water tank out through the walls of the water tank.

The tank cap 200 includes a plug 201. A first insulating layer 202, preferably insulating foam, is provided within the plug. The plug blocks the opening of the tank body when the tank cover is closed, and the plug opens the opening of the tank body when the tank cover is opened. Accordingly, the water storage in the heat preservation water tank is blocked through the opening and the heat transfer path from the outside, especially the heat transfer path from the heat convection to the outside. Specifically, the plug 201 includes an inner cover 205 connected to the underside of the water tank cover and a silica gel plug 206 sleeved on the inner cover, and the first insulation layer 202 is located in the inner cover 205. The inner cover of the plug is provided with the air holes 207, so that the phenomenon that the water tank is pumped into negative pressure by the water pump and the water yield is different is avoided.

In the figure, the mouth 101 of the tank is equipped with a transfer assembly 300, which is provided with a water filling port 301 corresponding to the mouth, and a plug 201 blocks the water filling port 301 when the tank cover is closed, and opens the water filling port when the tank cover is opened. Therefore, the water filling port 301 is regarded as a constituent part of the mouth portion 101.

The adapter assembly 300 includes an adapter cover 302, a top plate 303, and a second insulation layer 304. The adapter cap 302 is screwed to the mouth 101 of the case. A first sealing ring 305 is arranged between the transfer cover and the box body, the top plate and the transfer cover are clamped together, a second heat insulation layer 304 is positioned between the transfer cover and the top plate, and the second heat insulation layer is preferably heat insulation cotton. Furthermore, the adapter cover has an upwardly extending first guide ring 306, the top plate has a downwardly extending second guide ring 307, which is located inside and overlaps the first guide ring, and the water filling port 301 is defined by the second guide ring 307. Further, the top plate has a downward annular groove 308, in which a second sealing ring 309 is disposed, and the upper edge of the first guiding ring 306 presses the second sealing ring 309 into the annular groove 308. The top surface of the top plate is formed with a peripheral high, middle low bevel 310, and the second guide ring is located at the lowest position of the bevel.

The tank cover 200 is further provided with a hook 203, and the edge of the top plate 303 is provided with a hooking portion 311. When the water tank cover 200 is closed, the hook portion 311 is hooked by the hook 203, that is, the water tank cover is hooked by the adapter assembly, and the water tank cover is kept in a state of sealing and insulating the opening portion.

As shown in fig. 1-2, a water tank cover 200 is provided as an integral part of the top surface of the towel dispenser housing 20 and is configured to be flipped about an axis 204 to open or close the mouth. After the water tank cover is closed, the appearance is smooth and attractive, and the tank body is hidden.

Further, the water level sensor 400 for detecting whether the heat preservation water tank lacks water and the temperature sensor 500 for detecting the water temperature in the heat preservation water tank are assembled on the transfer cover, and the water level sensor and the temperature sensor are located at the lower side of the top plate and shielded by the top plate. The water level sensor and the temperature sensor are controlled by the system control main board 40 of the wet towel machine as shown in fig. 6. The water level sensor can detect the water level in the heat preservation water tank in real time, when the water level in the heat preservation water tank is reduced to a set position, the system control main board can instruct to alarm, and alarm forms include, but are not limited to, a phoenix ring or/and lamplight flickering, so that the problem that the water shortage alarm is caused once the water shortage alarm occurs in the towel making process due to the current change of the water pumping action of the water pump in the prior art is avoided. The water level sensor preferably adopts a floating mode, and when water shortage is detected, the residual water at the bottom of the water tank can ensure sufficient water quantity for wetting one towel. The temperature detected by the temperature sensor in real time can be displayed through the display panel, so that the temperature sensor is clear at a glance.

The box body 100 and the adapter assembly 300 assembled at the mouth are nested and installed in the case 20 of the wet towel machine through a top plate, so that the wet towel machine can be conveniently taken out from the case, and the water tank cover 200 is assembled on the case through a shaft. When water is added, water can be added to the water adding port by opening the water tank cover as shown in fig. 1 and 5, and water flow is guided by the inclined plane on the upper surface of the top plate, so that water flow overflow is avoided.

The heat preservation water tank is hidden in the wet towel machine, convenient to add water, and capable of preserving heat in vacuum and saving energy; the intelligent monitoring of the water temperature and the water quantity ensures that the water quantity of the towel which is being wetted is still sufficient when the water shortage alarm occurs in the towel making process.

In operation, the towel making switch 50 is pressed, the towel box is driven by the motor and the transmission mechanism to move a piece of compressed dry towel out of the machine box, and then the water pump can convey the water stored in the water tank to the towel box through the water pipe 80 to moisten the compressed dry towel of the towel box. Wherein the battery 60 provides power to the entire wet towel machine and may be charged through a charging interface or directly to the wet towel machine.
