DETAILED DESCRIPTION
[0027] 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.
[0028] In the embodiment, Figure 1-5 A humidifying device for a cell culture incubator is provided. The utility model comprises an incubator body 1, a water tank 2 is fixedly connected to the outside of the incubator body 1, a water inlet pipe 3 is fixedly connected to the inside of the water tank 2, an electric water valve 4 is arranged inside the water inlet pipe 3, a sliding rod 5 is fixedly connected to the inner bottom wall of the water tank 2, a sliding sleeve 6 is slidably connected to the outer side of the sliding rod 5, an air bag 7 is fixedly connected to the outer side of the sliding sleeve 6, a reaction block 8 located above the sliding rod 5 is fixedly connected to the inner top wall of the water tank 2, a humidifier 9 connected to the water tank 2 via a water pipe is fixedly connected to the inside of the incubator body 1, a partition frame 10 is fixedly connected to the inside of the partition frame 10, an electric push rod 11 is fixedly connected to the inside of the electric push rod 11, and a breathable plate 12 is fixedly connected to the outer side of the electric push rod 11.
[0029] The water inlet pipe 3 is connected to a water source, and a filter 13 is arranged inside the water inlet pipe 3 .
[0030] The water inlet pipe 3 is connected to water from a water source, which may be a faucet. The water passes through a filter 13 and then enters the water storage tank 2 through an electric water valve 4 .
[0031] The top of the sliding sleeve 6 is fixedly connected with a first contact piece 15 , the interior of the reaction block 8 is fixedly connected with a second contact piece 16 , and the height of the sliding sleeve 6 is higher than that of the airbag 7 .
[0032] When the water in the water tank 2 reaches a certain amount, the airbag 7 will float up and drive the first contact piece 15 outside the sliding sleeve 6 to contact the second contact piece 16, which will trigger the electric water valve 4 to close and stop the water supply.
[0033] The partition frame 10 has a plurality of evenly spaced first air permeable grooves disposed therein, the air permeable plate 12 has second air permeable grooves corresponding to the first air permeable grooves disposed therein, and the distance between two adjacent second air permeable grooves is consistent with the width of a single second air permeable groove.
[0034] The electric push rod 11 will push the air permeable plate 12 to move, and the second air permeable groove in the air permeable plate 12 after movement will be staggered with the first air permeable groove in the partition frame 10, so that the air permeable plate 12 blocks the flow of gas and reduces the gas flow speed. At this time, the cells can be taken.
[0035] There are two partition frames 10 , which are respectively located at the upper and lower sides of the humidifier 9 , and a baffle 17 is fixedly connected between the two partition frames 10 .
[0036] The water in the water storage tank 2 will flow into the humidifier 9 to provide moisture for the humidifier, and the baffle 17 prevents water vapor from escaping from the front.
[0037] Among them, two slide grooves are opened inside the single partition frame 10, and the front and rear sides of the air permeable plate 12 are fixedly connected with connecting plates 18, and the opposite sides of the two connecting plates 18 are fixedly connected with sliders 14 that are slidably connected to the two slide grooves respectively.
[0038] When the electric push rod 11 pushes the air-permeable plate 12 to move, the slider 14 moves in the slide groove, and the slide groove provides a moving space for the slider 14 and limits the moving direction of the slider 14 .
[0039] Working principle:
[0040] When the water in the water tank 2 flows into the humidifier 9, the amount of water in the water tank 2 decreases, and the airbag 7 descends. At this time, the two contact pieces are disconnected, and the electric water valve 4 opens to start supplying water. After the water volume rises to a certain level, the airbag rises along the sliding rod 5, and the two contact pieces re-contact, and the electric water valve 4 is closed. The incubator body 1 is provided with upper and lower cabinet doors. When cells on one side are to be taken out, the air permeable plate 12 is pushed by the electric push rod 11, and the air permeable grooves are staggered and closed. The cells are taken out by opening one cabinet door, while the air on the other side remains stable.
