The two transverse slots 14 are located on the periphery of the through hole 11. The inner walls of the two transverse slots 14 are arc-shaped. The two transverse slots 14 are respectively located on both sides of the through hole 11. The two transverse slots 14 are used to clamp the bottom of the oxygen humidification cup.
[0031] See Figure 2The water collecting seat 3 is concave as a whole, and four mounting posts 33 protruding from the bottom of the water collecting seat 3 are formed in the water collecting seat 3. The four mounting posts 33 are respectively located at the four corners of the bottom of the water collecting seat 3. The heating plate 2 is fixed on the four mounting posts 33. A protrusion 21 is formed on the heating plate 2. The heating plate 2 is located at the bottom of the mounting seat 1. The protrusion 21 on the heating plate 2 extends from the through hole 11. The bottom of the heating plate 2 is formed with four recesses 22 ( Figure 3 As shown in the figure, the top of the mounting post 33 is inserted into the recess 22 at the bottom of the heating plate 2. In order to facilitate the installation of the oxygen humidification cup, an elastic component can be installed between the recess 22 at the bottom of the heating plate 2 and the top of the mounting post 33. When installing the oxygen humidification cup, the protrusion 21 on the heating plate 2 is pressed down, and the bottom of the oxygen humidification cup is laterally inserted between the two horizontal slots 14 on the mounting seat 1. When the bottom of the oxygen humidification cup is clamped between the two horizontal slots 14, under the action of the elastic component, the protrusion 21 on the heating plate 2 pushes the bottom of the oxygen humidification cup upward, ensuring that the oxygen humidification cup can be firmly installed on the mounting seat 1. The heating plate 2 can also be firmly installed on the water collection seat 3 through the four mounting posts 33. When the heating plate 2 is working, the protrusion 21 on the heating plate 2 can heat the water in the oxygen humidification cup.
[0032] See Figure 2 The outer wall of the mounting post 33 is formed with a limiting rib 331. When the top of the mounting post 33 is inserted into the recess 22 at the bottom of the heating plate 2, the limiting rib 331 will not be inserted into the recess 22. The limiting rib 331 will abut upward against the periphery of the port of the recess 22 at its highest. Since the mounting post 33 protrudes from the inner bottom of the water collecting seat 3 and the limiting rib 331 exists, a gap will be left between the bottom of the heating plate 2 and the inner bottom of the water collecting seat 3, ensuring that the water collected in the water collecting seat 3 will not affect the heating plate 2.
[0033] See Figure 2 A water collecting trough 32 is formed on the inner bottom of the water collecting seat 3, and a drain pipe 31 is formed on the side of the water collecting seat 3. The drain pipe 31 is connected to the water collecting trough 32. The water in the gap between the through hole 11 of the mounting seat 1 and the raised portion 21 on the heating plate 2 can flow into the water collecting seat 3. The water flowing into the water collecting seat 3 converges into the water collecting trough 32 and is discharged through the drain pipe 31. The water collecting trough 32 can ensure that the water scattered in the water collecting seat 3 is completely gathered and easily discharged.
[0034] See Figure 2 and Figure 3The water collecting seat 3 is installed below the mounting seat 1, the heating disc 2 is located between the water collecting seat 3 and the bottom of the mounting seat 1, four fixed columns 34 are formed on the inner bottom of the water collecting seat 3, the fixed columns 34 protrude from the inner bottom of the water collecting seat 3, the four fixed columns 34 are respectively located at four corner positions of the inner bottom of the water collecting seat 3, the fixed columns 34 are axially formed with fixed holes 341 penetrating through the fixed columns 34, the bottom of the mounting seat 1 is formed with four inner threaded columns 15 matched with the positions of the fixed columns 34, the end portions of the inner threaded columns 15 abut against the top portions of the fixed columns 34, four fixed screws 5 are used to pass through the fixed holes 341 in the fixed columns 34 from the bottom of the water collecting seat 3 and are screwed into the inner threaded columns 15 in the bottom of the mounting seat 1, so that the assembly of the water collecting seat 3 and the mounting seat 1 is completed, and the water collecting seat 3 can be stably installed at the bottom of the mounting seat 1 through the fixed screws 5. Since the fixed columns 34 protrude from the inner bottom of the water collecting seat 3 and the inner threaded columns 15 exist, a space for accommodating the heating disc 2 is left between the water collecting seat 3 and the mounting seat 1.
[0035] Referring to Figure 2 In the embodiment, the top portions of the two fixed columns 34 are formed with concave accommodation cavities 342, the end portions of the inner threaded columns 15 can be accommodated in the accommodation cavities 342, in order to keep balance, the heights of the two fixed columns 34 provided with the accommodation cavities 342 are slightly higher than the heights of the other two fixed columns 34, so that during the process of installing the water collecting seat 3 on the mounting seat 1, as long as the end portions of the two inner threaded columns 15 in the bottom of the mounting seat 1 are inserted into the accommodation cavities 342 in the top portions of the fixed columns 34 on the water collecting seat 3, the position positioning of the water collecting seat 3 and the mounting seat 1 is completed, and then the fixed screws 5 are directly installed. In other embodiments, the top portions of the three fixed columns 34 can be formed with concave accommodation cavities 342 or the top portions of the four fixed columns 34 can be formed with concave accommodation cavities 342.
[0036] Referring to Figure 2 and Figure 3 The side portion of the mounting seat 1 is formed with a through hole 12 and a fixed hole 13, the free end of the drain pipe 31 on the water collecting seat 3 is inserted into the through hole 12, so that the water collecting seat 3 is installed in the inner side of the side portion of the mounting seat 1 and is not exposed; referring to Figure 2 and Figure 3The plug 4 is formed with a plug-in portion 41 and a fixed shaft 42. The plug-in portion 41 is plugged into the drain pipe 31, and the fixed shaft 42 is plugged and fixed in the fixing hole 13 and is not easy to fall out. When drainage is required, the plug-in portion 41 on the plug 4 is pulled out from the drain pipe 31. When drainage is not required, the plug-in portion 41 on the plug 4 is plugged into the drain pipe 31. The plug 4 can prevent foreign matter from entering or ants from crawling into the drain pipe 31, thereby ensuring the hygiene of the oxygen concentrator. When the plug-in portion 41 on the plug 4 is pulled out from the drain pipe 31, since the fixed shaft 42 is plugged and fixed in the fixing hole 13 on the mounting base 1, the plug 4 will not be separated from the mounting base 1, thereby preventing the plug 4 from being lost.
[0037] See Figure 2 and Figure 3 A pull-up portion 43 is formed on the rubber plug 4, and the rubber plug 4 can be easily pulled out from the drain pipe 31 through the pull-up portion 43.
[0038] See Figures 1 to 4 , the anti-overflow structure of the oxygen concentrator of the present invention, the mounting base 1 is mounted on the oxygen concentrator 100 ( Figure 4 As shown in FIG, when the oxygen humidifier cup is installed on the oxygen concentrator 100, the raised portion 21 on the heating disk 2 is pressed down, and the bottom of the oxygen humidifier cup is inserted horizontally between the two horizontal slots 14 on the mounting base 1. When the bottom of the oxygen humidifier cup is clamped between the two horizontal slots 14, the raised portion 21 on the heating disk 2 presses the bottom of the oxygen humidifier cup upward, and the bottom of the oxygen humidifier cup contacts the raised portion 21 on the heating disk 2. In the process of adding water to the oxygen humidifier cup, even if some water overflows or drips to the area where the bottom of the oxygen humidifier cup is located, even if there is residual water on the cup body of the oxygen humidifier cup, the water will flow downward into the water collecting seat 3 through the gap between the through hole 11 on the mounting base 1 below the oxygen humidifier cup and the raised portion 21 on the heating disk 2. The water flowing into the water collecting seat 3 converges into the water collecting tank 32 to ensure that the water does not leak. The user only needs to pull out the rubber plug 4 at intervals to open the drain pipe 31 and drain the water collected in the sump 32. For example, the water in the sump 32 can be drained through the drain pipe 31 by slightly tilting the oxygen concentrator 100. When drainage is not required, the plug 41 on the rubber plug 4 can be plugged into the drain pipe 31, which is very convenient. In addition, when the heating disk 2 is working, the raised portion 21 on the heating disk 2 can heat the water in the oxygen humidification cup. By controlling the heating disk 2 by the controller of the oxygen concentrator 100, the temperature of the water in the oxygen humidification cup can be maintained within a certain range, ensuring that the humidified oxygen maintains a certain temperature, so that the user can breathe comfortable oxygen.
[0039] The above merely describes some embodiments of the present application, which are intended to illustrate the technical means of the present application, and are not intended to limit the technical scope of the present application.
