[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0022] like Figs. 1 to 3 As shown, a contact-type water level protection device includes: two float bodies 100, a contact piece 200, a connecting pipe 300, and a slide rail 400; one float body 100 is disposed at one end of the connecting pipe 300, and the other float body 100 is disposed at the other end of the connecting pipe 300, and the connecting pipe 300 is slidably located on the slide rail 400; the contact piece 200 is disposed on the slide rail 400, and the connecting pipe 300 and the contact piece 200 are in movable contact.

[0023] Specifically, the number of the contact pieces 200 is four, and the four contact pieces 200 are all connected with external electrical signals. The four contact pieces 200 are all copper pieces. Further, the shape of the slide rail 400 is "U" type. The slide rail 400 comprises a mounting plate 410 and two limiting plates 420, one of which is vertically mounted on one end of the mounting plate 410, and the other of which is vertically mounted on the other end of the mounting plate 410. Each of the limiting plates 420 is provided with a limiting slot 421, and the connecting pipe 300 is movably arranged in the two limiting slots 421. Further, the connecting pipe 300 is a copper pipe.

[0024] In the above embodiment, the mounting plate 410 is provided with eight through holes 411, and each of the contact pieces 200 is arranged on one side of two through holes 411. Each of the contact pieces 200 is provided with two connecting terminals 210, and each of the connecting terminals 210 passes through one of the through holes 411. Each of the contact pieces 200 is detachably mounted on the mounting plate 410.

[0025] It is worth mentioning that the whole contact type water level protection device is used for being mounted on the humidifying product, such as being mounted in the internal machine of the oxygen generator, that is, being mounted in the oxygen generator which is integrated with the humidifying function by directly connecting the water to the internal machine of the oxygen generator. The contact type water level protection device is mounted in the internal machine of the oxygen generator.

[0026] The mounting plate 410 and the two limiting plates 420 of the slide rail 400 are injection molded, and the two floating ball bodies 100 are blow molded. Further, after the slide rail 400 is injection molded, the four contact sheets 200 are mounted on the mounting plate 410 of the slide rail 400, and each connecting terminal 210 on each contact sheet 200 passes through a through hole 411, and then an external signal line is connected. Then, the two floating ball bodies 100 are mounted on the connecting pipe 300, and the connecting pipe 300 is located in the two limiting grooves 421, that is, one end of the connecting pipe 300 is located in one limiting groove 421, and the other end is located in the other limiting groove 421. When placed in the water of the inner machine of the oxygen generator, the water level will first lift the floating ball body 100, that is, in the normal state, the connecting pipe 300 connected with the two floating ball bodies 100 will not abut against the four contact sheets 200 above. When the water level lifts the floating ball body 100 to the highest position of the slide rail 400, that is, the two ends of the connecting pipe 300 are located at the top of the two limiting grooves 421, at this time, the connecting pipe 300 will abut against each contact sheet 200. That is, since the material of the connecting pipe 300 and the contact sheet 200 is copper, after abutting, a loop is formed, that is, the signal line is connected, and since the signal line is connected with the outside, a signal is sent to the external control part, that is, when the control part receives the signal that the water level protection device forms a loop, it is judged that the inner machine of the oxygen generator is in the full water state, therefore, the external water inlet valve is controlled by the external control part to be closed, thereby avoiding the phenomenon that the floating ball is easily stuck or because the water contains too many impurities, the water level protection cannot be completed for a long time, which limits the extension of the service life.

[0027] That is, the water level protection can be well realized, the water tank is prevented from being filled with water when the water level is too high, the contact type structure is simple, the phenomenon of being stuck under low water pressure is avoided, the service life is long, and the device can be used in an environment with many impurities in the water.

[0028] In summary, the above-mentioned embodiments are not limiting embodiments of the present application, and any modification or equivalent deformation made by those skilled in the art on the basis of the essential content of the present application is within the technical scope of the present application.
