DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] In this embodiment, water can be injected into the water storage tank 3 through the water inlet 4 to store water. Figure 1-Figure 2 As shown:

[0033] A water tank 3 is installed inside the outer box body 1, a water inlet 4 is provided on the top of the water tank 3, and a display screen 5 is installed on the front side of the water tank 3;

[0034] When using the environmental climate box with low water level alarm, first place the outer box body 1 in the corresponding position to ensure the overall stability during use. A water storage tank 3 is arranged on the inner side of the outer box body 1, so the stable placement of the outer box body 1 can ensure the stability of the water storage tank 3. When it is necessary to fill water into the water storage tank 3, the box door 2 can be opened to expose the water storage tank 3. A water inlet 4 is arranged on the top of the water storage tank 3, so water can be filled into the water storage tank 3 through the water inlet 4.

[0035] Embodiment 2:

[0036] In this embodiment, when the buoyancy plate 6 contacts the bottom of the limiting rod 14, the sealing plug 8 will engage the inside of the water inlet 4, so that the sealing plug 8 blocks the water inlet 4. Figure 5-Figure 6 As shown:

[0037] A limit rod 14 is installed on the top inner wall of the water storage tank 3, and a water pump 15 is arranged on the outside of the water storage tank 3;

[0038] A first through hole 7 is provided on the buoyancy plate 6, and a sealing plug 8 is installed on the upper surface of the buoyancy plate 6, and the sealing plug 8 is made of rubber, and the outer diameter of the sealing plug 8 is equal to the inner diameter of the water inlet 4, a second through hole 10 is provided on the limit plate 9, and a protective cover body 11 is provided on the upper surface of the limit plate 9, and a micro switch 12 is installed inside the protective cover body 11, and the protective cover body 11 is made of rubber. The limit rod 14 and the top inner wall of the water storage tank 3 are welded, and the bottom of the limit rod 14 and the buoyancy plate 6 are not connected, and the length of the limit rod 14 is 5 cm, and the height of the sealing plug 8 is 5 cm;

[0039] A buoyancy plate 6 is arranged on the inner side of the water storage tank 3, and a first through hole 7 is opened on the buoyancy plate 6. The buoyancy plate 6 is made of plastic, so that when water is filled, water can flow through the first through hole 7 on the buoyancy plate 6 to store water. As the amount of water increases, the buoyancy plate 6 will gradually rise. A limiting rod 14 is installed on the top inner wall of the water storage tank 3, and a sealing plug 8 is installed on the upper surface of the buoyancy plate 6. The sealing plug 8 is made of rubber, and the position of the sealing plug 8 corresponds to the position of the water inlet 4. When the buoyancy plate 6 rises, the sealing plug 8 will be driven to rise together. When the buoyancy plate 6 contacts the bottom of the limiting rod 14, the sealing plug 8 will be engaged with the inside of the water inlet 4, so that the sealing plug 8 blocks the water inlet 4, so that external water no longer enters, and the length of the limiting rod 14 is 5 cm, which can effectively prevent overflow caused by excessive water injection.

[0040] Embodiment three:

[0041] In this embodiment, when the buoyancy board 6 descends and contacts the micro switch 12, the micro switch 12 is turned on, so that the alarm 13 sounds an alarm, achieving the purpose of low water level alarm. Figure 3-Figure 4 As shown:

[0042] A low water level warning structure is provided inside the water storage tank 3, and the warning structure includes a buoyancy plate 6, and a limit plate 9 is installed on the bottom inner wall of the water storage tank 3;

[0043] An alarm 13 is installed on the top of the water tank 3 by screws, and the alarm 13 and the micro switch 12 are electrically connected;

[0044] The limiting plate 9 and the inner wall of the water storage tank 3 are welded, and there is a gap between the lower surface of the limiting plate 9 and the bottom of the water storage tank 3;

[0045] The inlet end of the water pump 15 is connected to one end of the water pumping pipe 16, and the other end of the water pumping pipe 16 passes through the buoyancy plate 6 and is located inside the water storage tank 3, and the outlet end of the water pump 15 is installed with a water outlet pipe 17;

[0046] Start the water pump 15, the water pump 15 will pump out the water in the water tank 3 through the pumping pipe 16, and then discharge the water through the outlet pipe 17. The outlet pipe 17 can be connected to the dehumidification mechanism, so that the dehumidification mechanism can be supplied with water to ensure the normal dehumidification work. As the water level in the water tank 3 decreases, the buoyancy plate 6 will gradually decrease. Since a limit plate 9 is fixed on the inner wall of the water tank 3, and a micro switch 12 is installed on the upper surface of the limit plate 9, the micro switch 12 and the alarm 13 are electrically connected, and the micro switch 12 is turned on. It is protected by a protective cover body 11 made of rubber material, so when the buoyancy plate 6 descends and contacts the microswitch 12, the microswitch 12 will be turned on, which will cause the alarm 13 to sound an alarm. There is a gap between the limit plate 9 and the bottom of the water tank 3. When the alarm 13 sounds an alarm, the water level is at the lowest position, reminding the staff to add water in time to prevent water shortage. The above is the working process of the entire device.
