Description

Technical Field

[0001] This utility model relates to the field of oxygen generators, and in particular to a heating plate base structure for an oxygen humidification cup in an oxygen generator. Background Technology

[0002] Oxygen concentrators are widely used in homes, hospitals, sanatoriums, schools, hotels, sports venues, bars, oxygen bars, and high-altitude military stations. With the increasing awareness of health, the market for home oxygen concentrators with oxygen humidification cups, heating plates, and base supports is gradually emerging, making them an important health care device. As a home medical device, its market demand continues to grow with people's pursuit of a healthy life.

[0003] The oxygen humidification cup of an oxygen concentrator is an important accessory. Its main function is to humidify the oxygen produced by the oxygen concentrator so that the oxygen is moistened before inhalation, reducing discomfort to the respiratory tract.

[0004] Oxygen humidification cups are generally detachably connected to oxygen concentrators. However, some existing oxygen concentrators have complex structures for installing oxygen humidification cups, making installation and removal of the cups quite troublesome.

[0005] In addition, during normal use, water needs to be added to the oxygen humidifier cup to ensure oxygen humidification. During the water addition process, some water will inevitably overflow or drip onto the base where the oxygen humidifier cup is installed, and residual water on the oxygen humidifier cup will also flow onto the base where the oxygen humidifier cup is installed. Over time, this water may seep into the oxygen concentrator and affect the internal components, especially the circuit board components. Users usually wipe it with a cloth during use, but sometimes forgetting to wipe or not wiping it properly will affect the normal operation of the oxygen concentrator. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heating plate base structure for an oxygen humidification cup of an oxygen generator.

[0007] According to one aspect of the present invention, an oxygen humidification cup heating plate base structure for an oxygen concentrator is provided, comprising:

[0008] A mounting bracket for installation on an oxygen concentrator, the mounting bracket has a through hole and two horizontal slots for engaging an oxygen humidification cup, the two horizontal slots being located around the through hole;

[0009] Heating plate, the heating plate has a protrusion, the heating plate is located at the bottom of the mounting base and the protrusion on the heating plate extends out of the through hole;

[0010] The base is located below the heating element; and

[0011] The elastic component is located between the heating plate and the base. One end of the elastic component presses against the base, and the other end presses against the bottom of the heating plate. The elastic component can cause the protrusion on the heating plate to move upward in the through hole.

[0012] This utility model discloses an oxygen humidification cup heating plate base structure for an oxygen concentrator. The mounting base is installed on the oxygen concentrator. When installing the oxygen humidification cup, the protrusion on the heating plate is pressed down, and the bottom of the oxygen humidification cup is horizontally inserted between the two horizontal slots on the mounting base. Due to the presence of elastic components, the protrusion on the heating plate will push upward against the bottom of the oxygen humidification cup, thus completing the installation of the oxygen humidification cup. The oxygen humidification cup can be securely installed on the mounting base. When it is necessary to remove the oxygen humidification cup, it can be pulled out horizontally outward from the two horizontal slots. The installation and removal of the oxygen humidification cup are very simple. In addition, when the heating plate is working, the protrusion on the heating plate can heat the water in the oxygen humidification cup. Through the control of the oxygen concentrator's controller, 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, allowing the user to breathe comfortable oxygen.

[0013] Furthermore, the elastic component is a compression spring, and there are four compression springs. The base is provided with four mounting posts, and the bottom of the heating plate is provided with four recesses. The tops of the four mounting posts are respectively accommodated in the four recesses. The four compression springs are respectively sleeved on the mounting posts, with one end of the compression spring pressing against the base and the other end of the compression spring pressing against the inner bottom of the recess. Therefore, the heating plate can be installed on the base through the cooperation of the mounting post and the cavity. There is a gap between the bottom of the heating plate and the base to provide space for the base to collect overflow water. Under the elastic force of the compression spring, the protrusion always maintains an upward pushing tendency. When the bottom of the oxygen humidification cup is horizontally inserted between the two horizontal slots on the mounting base, under the action of the compression spring, the protrusion on the heating plate will push upward against the bottom of the oxygen humidification cup, ensuring that the oxygen humidification cup can be stably installed on the mounting base. When installing the oxygen humidification cup, simply press the protrusion downward and then horizontally insert the oxygen humidification cup between the two horizontal slots. The structure is simple, and the installation and removal of the oxygen humidification cup is very simple. When the oxygen humidification cup is not installed, the compression spring causes the protrusion to move upward to the highest point in the through hole.

[0014] Furthermore, the outer wall of the mounting post is provided with multiple limiting ribs. One end of the compression spring presses against the limiting ribs, and the other end presses against the inner bottom of the recess. Therefore, when the top of the mounting post is inserted into the recess at the bottom of the heating plate, the limiting ribs will not be inserted into the recess. The limiting ribs will rise upwards and abut against the periphery of the recess's opening. The presence of the limiting ribs allows for a gap between the bottom of the heating plate and the base, providing space for the base to collect overflow water and ensuring that the water collected in the base will not affect the heating plate.

[0015] Furthermore, it also includes fixing screws, and the base has four fixing posts with fixing holes along the axial direction. The bottom of the mounting base has four internally threaded posts that fit the fixing posts. The ends of the internally threaded posts press against the tops of the fixing posts, and the fixing screws pass through the fixing holes and are screwed into the internally threaded posts. Therefore, the base can be securely installed on the bottom of the mounting base by fixing screws. Due to the presence of the fixing posts and internally threaded posts, there is space between the base and the mounting base to accommodate the heating plate.

[0016] Furthermore, at least two of the fixing posts have receiving cavities at their tops, and the ends of the internally threaded posts can be accommodated in these cavities. Therefore, during the installation of the base onto the mounting base, simply ensure that the ends of the internally threaded posts at the bottom of the mounting base are inserted into the receiving cavities at the tops of the fixing posts on the base to complete the positioning of both, and then directly install the fixing screws.

[0017] Furthermore, the base is concave, and a drain pipe is located on the side of the base, allowing water in the gap between the through hole and the protrusion to flow into the base. Therefore, during the process of adding water to the oxygen humidification cup, even if some water overflows or drips to the bottom area of ​​the oxygen humidification cup, or even if there is residual water on the cup body, this water will flow down through the gap between the through hole and the protrusion at the bottom of the oxygen humidification cup into the concave base. This ensures that the water will not seep into the oxygen concentrator and affect the internal components, especially the circuit board components. Users do not need to frequently wipe the base with a cloth; they can simply open the drain pipe periodically to drain the water collected in the base, which is very convenient.

[0018] Furthermore, a water collection trough is provided on the inner bottom of the base, and the water collection trough is connected to the drain pipe. Therefore, the water flowing into the base flows into the water collection trough and is discharged through the drain pipe. The water collection trough can ensure that the water scattered in the base is collected and easily drained away.

[0019] Furthermore, it also includes a rubber stopper with an insertion part. The side of the mounting base has a through hole, and the free end of the drain pipe is inserted into the through hole, while the insertion part is inserted into the drain pipe. Therefore, the base can be installed inside the side of the mounting base without being exposed. When drainage is needed, the insertion part on the rubber stopper is pulled out of the drain pipe, and the water in the base can be drained away through the drain pipe. When drainage is not needed, the insertion part on the rubber stopper is inserted into the drain pipe to prevent foreign objects or ants from entering, ensuring the hygiene of the oxygen concentrator.

[0020] Furthermore, the rubber stopper is equipped with a fixing shaft, and the side of the mounting base has a fixing hole, in which the fixing shaft is inserted and fixed. Therefore, when the plug on the rubber stopper is pulled out of the drain pipe, the rubber stopper will not separate from the mounting base because the fixing shaft is inserted and fixed in the fixing hole on the mounting base, thus preventing the rubber stopper from being lost.

[0021] Furthermore, the rubber stopper is provided with a pull-up part. Therefore, the rubber stopper can be easily pulled out of the drain pipe using the pull-up part. Attached Figure Description

[0029] See Figures 1 to 4 An oxygen humidification cup heating plate base structure for an oxygen generator includes a mounting base 1, a heating plate 2, a base 3, an elastic component, a fixing screw 5, and a rubber stopper 6.

[0030] See Figure 1 , Figure 2 and Figure 4 Mounting bracket 1 is used to install on the oxygen concentrator. Figure 5 As shown, mounting base 1 can be adapted to be installed on top of the oxygen concentrator.

[0031] See Figure 1 and Figure 2 The mounting base 1 has a recessed corner for mounting an oxygen humidification cup. The recessed position of the mounting base 1 has a through hole 11 and two horizontal slots 12. The two horizontal slots 12 are located around the through hole 11. The inner walls of the two horizontal slots 12 are arc-shaped. The two horizontal slots 12 are located on both sides of the through hole 11. The two horizontal slots 12 are used to engage the bottom of the oxygen humidification cup.

[0032] See Figures 1 to 3 The heating plate 2 has a protrusion 21 formed on it. The heating plate 2 is located at the bottom of the mounting base 1. The protrusion 21 on the heating plate 2 extends out from the through hole 11.

[0033] The elastic component is located between the heating plate 2 and the base 3. One end of the elastic component presses against the base 3, and the other end presses against the bottom of the heating plate 2. The elastic component can cause the protrusion 21 on the heating plate 2 to move upward in the through hole 11. Specifically, in this embodiment, the elastic component is a compression spring 4, and there are four compression springs 4. See [reference needed] Figure 2The base 3 is concave and extends upward from the bottom perimeter. Four mounting posts 31 protruding from the bottom of the base 3 are formed therein, located at the four corners of the bottom. The heating plate 2 is mounted on the four mounting posts 31. (See reference...) Figure 4 The bottom of the heating plate 2 has four recesses 22 that mate with the mounting posts 31. The top of the mounting posts 31 is inserted into the recesses 22 at the bottom of the heating plate 2. (See reference...) Figure 2 Four compression springs 4 are respectively fitted onto the mounting post 31. One end of the compression spring 4 presses against the base 3, and the other end presses against the inner bottom of the cavity 22. Under the elastic force of the compression spring 4, the protrusion 21 on the heating plate 2 always maintains an upward pushing tendency. When installing the oxygen humidification cup, press down the protrusion 21 on the heating plate 2 and insert the bottom of the oxygen humidification cup horizontally between the two horizontal slots 12 on the mounting base 1. When the bottom of the oxygen humidification cup is engaged between the two horizontal slots 12, under the action of the compression spring 4, the protrusion 21 on the heating plate 2 pushes upward against the bottom of the oxygen humidification cup, ensuring that the oxygen humidification cup can be stably installed on the mounting base 1. The heating plate 2 can be stably installed on the base 3 through the cooperation of the mounting post 31 and the cavity 22. There is a gap between the bottom of the heating plate 2 and the base 3 to provide space for the base 3 to collect overflow water. When the heating plate 2 is working, the protrusion 21 on the heating plate 2 can heat the water in the oxygen humidification cup.

[0034] See Figure 2 In this embodiment, multiple limiting ribs 311 are formed on the outer wall of the mounting post 31. The multiple limiting ribs 311 are arranged around the outer wall of the mounting post 31. The lower end of the compression spring 4 presses against the limiting ribs 311, and the upper end of the compression spring 4 presses against the inner bottom of the cavity 22 at the bottom of the heating plate 2. When the top of the mounting post 31 is inserted into the cavity 22 at the bottom of the heating plate 2, the limiting ribs 311 will not be inserted into the cavity 22. The limiting ribs 311 will at most abut against the periphery of the port of the cavity 22. Due to the presence of the mounting post 31 protruding from the inner bottom of the base 3 and the limiting ribs 311, a gap will be left between the bottom of the heating plate 2 and the inner bottom of the base 3. Figure 3 As shown, this provides space for the base 3 to collect overflow water, ensuring that the water collected in the base 3 will not affect the heating plate 2.

[0035] See Figure 2 The base 3 is installed below the mounting base 1, and the heating plate 2 is located between the base 3 and the bottom of the mounting base 1. (See reference) Figure 2 and Figure 3Four fixing posts 33 are formed on the inner bottom of the base 3. The fixing posts 33 protrude from the inner bottom of the base 3 and are located at the four corners of the inner bottom of the base 3. Fixing holes 331 are formed on the fixing posts 33 along the axial direction. The bottom of the mounting base 1 is formed with four internally threaded posts 13 that are adapted to the positions of the fixing posts 33. Figure 4 As shown), the end of the internally threaded post 13 presses against the top of the fixed post 33. (See reference) Figure 4 Four fixing screws 5 are used to pass through the fixing holes 331 on the fixing post 33 from the bottom of the base 3 and screw them into the internal thread post 13 at the bottom of the mounting base 1, thereby completing the assembly of the base 3 and the mounting base 1. The base 3 can be firmly installed on the bottom of the mounting base 1 by fixing screws 5. Due to the protrusion of the fixing post 33 on the inner bottom of the base 3 and the existence of the internal thread post 13, there will be space between the base 3 and the mounting base 1 to accommodate the heating plate 2.

[0036] See Figure 2 In this embodiment, the tops of both fixing posts 33 are formed with concave receiving cavities 332, and the ends of the internally threaded posts 13 can be accommodated in the receiving cavities 332. To maintain balance, the height of the two fixing posts 33 with receiving cavities 332 is slightly higher than the height of the other two fixing posts 33. In this way, during the process of installing the base 3 on the mounting base 1, as long as the ends of the two internally threaded posts 13 at the bottom of the mounting base 1 are inserted into the receiving cavities 332 at the tops of the fixing posts 33 on the base 3, the position of the base 3 and the mounting base 1 can be completed, and then the fixing screws 5 can be directly installed. In other embodiments, the tops of all three fixing posts 33 are formed with concave receiving cavities 332, or the tops of all four fixing posts 33 are formed with concave receiving cavities 332.

[0037] See Figure 2 A water collection trough 35 is formed on the inner bottom of the base 3, and a drain pipe 34 is formed on the side of the base 3. The drain pipe 34 is connected to the water collection trough 35. Water in the gap between the through hole 11 of the mounting base 1 and the protrusion 21 on the heating plate 2 can flow into the base 3. The water flowing into the base 3 flows into the water collection trough 35 and is discharged through the drain pipe 34. The water collection trough 35 can ensure that the water scattered in the base 3 is collected and easily drained away.

[0038] See Figure 2 The side of the mounting base 1 is formed with a through hole 14 and a fixing hole 15. The free end of the drain pipe 34 on the base 3 is inserted into the through hole 14. In this way, the base 3 is installed inside the side of the mounting base 1 and is not exposed. See reference Figure 2The rubber stopper 6 has an insertion part 61 and a fixing shaft 62 formed on it. The insertion part 61 is inserted into the drain pipe 34, and the fixing shaft 62 is inserted into and fixed in the fixing hole 15 and is not easy to come out. When drainage is needed, the insertion part 61 on the rubber stopper 6 is pulled out from the drain pipe 34. When drainage is not needed, the insertion part 61 on the rubber stopper 6 is inserted into the drain pipe 34. The rubber stopper 6 can prevent foreign objects from entering or ants from crawling into the drain pipe 34, ensuring the hygiene of the oxygen concentrator. When the insertion part 61 on the rubber stopper 6 is pulled out from the drain pipe 34, the rubber stopper 6 will not separate from the mounting base 1 because the fixing shaft 62 is inserted into and fixed in the fixing hole 15 on the mounting base 1, thus preventing the rubber stopper 6 from being lost.

[0039] See Figure 2 The rubber stopper 6 has a pull-up part 63 formed on it, which can be used to easily pull the rubber stopper 6 out of the drain pipe 34.

[0040] See Figures 1 to 5 The oxygen humidification cup heating plate base structure of the oxygen concentrator of this utility model is mounted on the oxygen concentrator 100 by the mounting base 1. Figure 5As shown, when installing the oxygen humidification cup on the oxygen concentrator 100, press down the protrusion 21 on the heating plate 2 and insert the bottom of the oxygen humidification cup horizontally between the two horizontal slots 12 on the mounting base 1. When the bottom of the oxygen humidification cup is engaged between the two horizontal slots 12, under the action of the four compression springs 4, the protrusion 21 on the heating plate 2 contacts the bottom of the oxygen humidification cup and the protrusion 21 on the heating plate 2 pushes upward against the bottom of the oxygen humidification cup. At this time, the installation of the oxygen humidification cup is completed. When the oxygen humidification cup needs to be removed, simply pull the oxygen humidification cup horizontally outward from the two horizontal slots 12. The installation and removal of the oxygen humidification cup are very simple. Moreover, during the process of adding water to the oxygen humidification cup, even if some water overflows or drips into the area where the bottom of the oxygen humidification cup is located, even if there is residual water on the cup body, this water will pass through the through hole 11 on the mounting base 1 located below the oxygen humidification cup and the protrusion on the heating plate 2. The water flows down into the base 3 through the gap between 21, and then into the water collection tank 35. This ensures that the water will not seep into the oxygen concentrator 100 and affect the internal components, especially the circuit board components. Users do not need to wipe the machine frequently with a cloth. They can simply pull out the rubber stopper 6 and open the drain pipe 34 at intervals to drain the water collected in the water collection tank 35. By slightly tilting the oxygen concentrator 100, the water in the water collection tank 35 can be drained through the drain pipe 34. When drainage is not needed, simply insert the plug 61 on the rubber stopper 6 into the drain pipe 34. This is very convenient. In addition, when the heating plate 2 is working, the protrusion 21 on the heating plate 2 can heat the water in the oxygen humidification cup. By controlling the heating plate 2 through 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 is kept at a certain temperature so that users can breathe comfortable oxygen.

[0041] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art based on existing common knowledge fall within the protection scope of this utility model.
