Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to a noise-absorbing diffusion gas box and a control terminal for a diffusion oxygen generator. Background Technology

[0002] A diffusion oxygen generator is a device that increases the oxygen concentration in an environment through diffusion. It is primarily used to improve the overall oxygen content of indoor spaces. Its core principle is to separate oxygen from the air using molecular sieve technology and release it into the surrounding air in a diffused form. A diffusion oxygen generator typically consists of an outdoor oxygen generator unit and an indoor control terminal. The control terminal can control the start and stop of the oxygen generator unit and provide the oxygen produced by the unit to people indoors.

[0003] The diffused gas box is an important component of the control terminal. It has an internal gas chamber and an external air inlet and diffusion holes that communicate with the gas chamber. Oxygen produced by the oxygen generator enters the gas chamber through a pipe connected to the air inlet. The oxygen is then buffered in the gas chamber and released directly into the indoor space through the diffusion holes to increase the overall oxygen content of the indoor space. However, because the oxygen is released directly into the indoor space after passing through the diffusion holes, the diffused gas box generates a lot of noise when dispersing oxygen, and the diffusion effect of the diffused gas box is poor, which affects the user experience. Utility Model Content

[0004] This application provides a noise-reducing diffusion gas box to reduce the noise generated when the diffusion gas box diffuses oxygen and improve the diffusion effect of oxygen, thereby improving the user experience.

[0005] The technical solution adopted in this application is as follows:

[0006] A noise-absorbing gas box, comprising:

[0007] The box body has an air-containing cavity inside, and the box body is provided with an air inlet communicating with the air-containing cavity and a plurality of air outlets communicating with the air-containing cavity.

[0008] The decorative component has annular ribs surrounding the multiple air vents. The decorative component, the annular ribs, and the box body together form a diffusion cavity. The decorative component has multiple diffusion holes communicating with the diffusion cavity, and the number of diffusion holes is greater than the number of air vents.

[0009] By adopting the above technical solution, when the control terminal with the silencer diffusion gas box of this application is working, the oxygen produced by the oxygen generator enters the gas chamber through the air inlet, so that the oxygen diffuses in the gas chamber and then enters the diffusion chamber through the air outlet. The oxygen in the diffusion chamber diffuses again and is released into the room through the diffusion hole, so as to realize the release of the oxygen produced by the oxygen generator into the room by diffusion.

[0010] Because oxygen undergoes multiple diffusion processes when released into the room through diffusion, the kinetic energy of the oxygen discharged through the diffusion holes is greatly reduced, thereby significantly reducing the noise generated when the silencer diffusion box diffuses and releases oxygen, and thus greatly improving the user experience.

[0011] Furthermore, since the number of diffusion holes is greater than the number of air outlet holes, the oxygen in the diffusion chamber is released through multiple diffusion holes, which greatly improves the diffusion effect of oxygen by the silencer diffusion air box, thereby further improving the user experience.

[0012] Optionally, the outer surface of the box body is provided with connecting ribs surrounding the plurality of air vents, and one of the connecting ribs and the annular ribs is provided with a sealing groove, and the other of the two is provided with a sealing rib extending into the sealing groove.

[0013] By adopting the above technical solution, the connecting ribs surrounding multiple air outlets on the outside of the box body further increase the volume of the diffusion chamber, thereby further reducing the kinetic energy of oxygen when it is discharged through the diffusion holes, and thus further improving the noise reduction effect of the silencer diffusion air box. Furthermore, since one of the connecting ribs and the annular ribs is provided with a sealing groove, and the other is provided with a sealing rib extending into the sealing groove, on the one hand, the cooperation between the sealing rib and the sealing groove can position the decorative parts and the box body, reducing the difficulty of assembling the decorative parts and the box body together, improving the assembly efficiency of the silencer diffusion air box, and thus reducing the assembly cost of the silencer diffusion air box; on the other hand, the cooperation between the sealing groove and the sealing rib can also increase the sealing performance of the connection between the connecting rib and the annular rib, ensuring the airtightness of the diffusion chamber.

[0014] Optionally, the box body has an air inlet end and an air outlet end, and at least one side of the air outlet end is recessed into the interior of the box body with a clearance notch, and a plurality of air outlet holes are provided on the wall surface of the clearance notch.

[0015] By adopting the above technical solution, since multiple air vents are located on the wall surface of the clearance notch, after the decorative parts are assembled into the box body, the annular rib can be located in the clearance notch, thereby reducing the volume of the sound-absorbing and diffusing air box and thus achieving the effect of facilitating the miniaturization design of the sound-absorbing and diffusing air box.

[0016] Optionally, the housing includes a first outer shell and a second outer shell that together form the air cavity. The air cavity is provided with multiple partitions for dividing the air cavity into multiple buffer chambers. Each partition forms a communication port with the cavity wall of the air cavity, and adjacent communication ports are staggered.

[0017] By adopting the above technical solution, since the box body includes a first outer shell and a second outer shell that together form the gas cavity, the production difficulty of the box body is reduced, thereby reducing the yield rate and production cost of the box body. Furthermore, since each partition forms a communication port with the cavity wall of the gas cavity, and adjacent communication ports are staggered, the movement path of oxygen in the gas cavity is increased, thereby increasing the kinetic energy consumption of oxygen flowing in the gas cavity, further reducing the kinetic energy of oxygen when it exits through the diffusion holes, and thus further improving the noise reduction effect of the silencer diffuser gas box; at the same time, it further increases the number of oxygen diffusion movements, further reducing the kinetic energy of oxygen when it exits through the diffusion holes, and further improving the noise reduction effect of the silencer diffuser gas box.

[0018] Optionally, the box body has a length direction, and a plurality of buffer chambers are arranged sequentially along the length direction. The air inlet is connected to the buffer chamber located at one end of the length direction of the box body, and the plurality of air outlets are all connected to the buffer chamber located at the other end of the length direction of the box body.

[0019] By adopting the above technical solution, since multiple buffer cavities are arranged sequentially along the length of the box, the distribution of the buffer cavities inside the box is more regular, thereby further reducing the production difficulty of the box. Since the air inlet is connected to the buffer cavity located at one end of the length of the box, and multiple air outlets are connected to the buffer cavity located at the other end of the length of the box, the oxygen can pass through multiple buffer cavities sequentially when flowing in the gas chamber, so as to ensure the movement path of the oxygen in the gas chamber, thereby ensuring the consumption effect of oxygen kinetic energy, and thus ensuring the noise reduction effect of the silencer diffuser box.

[0020] Optionally, the partition includes a first partition disposed on the first outer shell and a second partition disposed on the second outer shell, the first partition and the second partition being disposed opposite to each other, the communication port including a first communication port and a second communication port intersecting the first communication port in the length direction of the box body, one of the two adjacent first partitions forming the first communication port between the first partition and the cavity wall of the gas cavity, and one of the two adjacent second partitions forming the second communication port between the second partition and the cavity wall of the gas cavity.

[0021] By adopting the above technical solution, since the first and second connecting ports are staggered along the length of the box, and one of the two adjacent first partitions forms a first connecting port with the cavity wall of the gas chamber, and one of the two adjacent second partitions forms a second connecting port with the cavity wall of the gas chamber, the movement path of oxygen in the gas chamber is further increased, thereby further improving the kinetic energy consumption of oxygen in the gas chamber. This further reduces the kinetic energy of oxygen when it is discharged from the diffusion chamber through the diffusion hole, thus further improving the noise reduction effect of the silencer diffusion gas box and further improving the user experience.

[0022] Optionally, the first housing has a first mating surface facing the second housing, the second housing has a second mating surface facing the first housing, one of the first mating surface and the second mating surface is provided with a positioning groove, and the other of the two is provided with a positioning rib extending into the positioning groove.

[0023] By adopting the above technical solution, since one of the first mating surface and the second mating surface is provided with a positioning groove, and the other of the two is provided with a positioning rib extending into the positioning groove, on the one hand, the positioning rib and the positioning groove can be used to limit the first shell and the second shell, thereby reducing the difficulty of assembling the first shell and the second shell together and improving the assembly efficiency of the box. On the other hand, the cooperation between the positioning rib and the positioning groove can also increase the sealing between the first shell and the second shell, thereby ensuring the airtightness of the air chamber.

[0024] Optionally, the air chamber is filled with noise-reducing cotton so that oxygen entering the air chamber through the air inlet moves inside the noise-reducing cotton and is eventually discharged through the air outlet.

[0025] By adopting the above technical solution, since the gas cavity is filled with noise-reducing cotton, the oxygen entering the gas cavity moves inside the noise-reducing cotton, thereby reducing the noise generated by the contact friction between the oxygen flow and the cavity wall, and further improving the noise reduction effect of the silencer diffused gas box.

[0026] Optionally, an air inlet nozzle is provided extending outward from the air inlet, and an air inlet pipe is connected to the air inlet nozzle, with a regulating valve provided in the air inlet pipe.

[0027] By adopting the above technical solution, since an air inlet is provided extending outward at the air inlet, it is easy to connect the air inlet pipe to the air inlet, thereby reducing the assembly difficulty of the control terminal; since a regulating valve is provided in the air inlet pipe, the oxygen flow rate and pressure in the input gas chamber can be adjusted by the regulating valve, thereby reducing the pressure of oxygen entering the gas chamber, and further improving the noise reduction effect of the silencer diffuser box.

[0028] This application also provides a control terminal for a diffusion oxygen generator to reduce the noise generated during operation of the control terminal and improve the diffusion effect of the control terminal on oxygen.

[0029] A control terminal for a diffusion oxygen generator includes a housing and a sound-absorbing diffusion gas box as described above, wherein the decorative part is integrally formed with the housing;

[0030] Alternatively, the housing may be provided with mounting holes, and the decorative element may be disposed in the mounting holes.

[0031] By adopting the above technical solution, the control terminal uses the aforementioned silencer and diffuser box, which reduces the noise generated during operation and improves the oxygen diffusion effect, thereby enhancing the user experience.

[0032] Because the decorative parts are integrally molded with the housing, the number of components required to assemble the control terminal is reduced, thereby improving the assembly efficiency of the control terminal and reducing the assembly cost of the control terminal.

[0033] Because the housing has mounting holes, and decorative parts are placed in the mounting holes, the production difficulty of the housing is reduced, thereby reducing the production cost of the housing.

[0034] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0035] 1. The silencer diffuser box in this application includes a box body and decorative parts. The box body has an air-containing cavity inside. The box body is provided with an air inlet communicating with the air-containing cavity and multiple air outlets communicating with the air-containing cavity. The decorative parts are provided with annular ribs surrounding the multiple air outlets. The decorative parts, annular parts, and box body together form a diffuser cavity. The decorative parts are provided with multiple diffuser holes communicating with the diffuser cavity, and the number of diffuser holes is greater than the number of air outlets. As a result, when oxygen is released into the room through the silencer diffuser box in a diffuse manner, the oxygen undergoes multiple diffusion movements, which greatly reduces the kinetic energy of the oxygen discharged through the diffuser holes. This greatly reduces the noise generated when the silencer diffuser box diffuses and releases oxygen, while improving the diffusion effect of the silencer diffuser box on oxygen, thereby improving the user experience.

[0036] 2. The outer surface of the box body in this application is provided with connecting ribs surrounding multiple air outlets, which further increases the volume of the diffusion cavity, thereby further reducing the kinetic energy of oxygen when it is discharged through the diffusion holes, and thus further improving the sound absorption effect of the silencer diffusion air box; one of the connecting ribs and the annular ribs is provided with a sealing groove, and the other of the two is provided with a sealing rib extending into the sealing groove. On the one hand, the cooperation between the sealing rib and the sealing groove can position the decorative parts and the air box, thereby reducing the difficulty of assembling the decorative parts with the box body, improving the assembly efficiency of the silencer diffusion air box, and thus reducing the assembly cost of the silencer diffusion air box. On the other hand, the cooperation between the sealing groove and the sealing rib can also increase the connection and sealing performance between the connecting rib and the annular rib, so as to ensure the airtightness of the diffusion cavity.

[0037] 3. The box body in this application has an air inlet end and an air outlet end. At least one side of the air outlet end is recessed into the interior of the box body and a clearance notch is provided. Multiple air outlet holes are provided on the wall surface of the clearance notch. After the decorative parts are assembled into the box body, the annular rib can be located in the clearance notch to reduce the volume of the sound-absorbing and diffusing air box, thereby achieving the effect of facilitating the miniaturization design of the sound-absorbing and diffusing air box.

[0054] Reference Figures 1 to 8 A noise-absorbing diffused air box is disclosed, which includes a box body 1 and a decorative part 2. The box body 1 has an air-containing cavity 13 inside, and the box body 1 is provided with an air inlet communicating with the air-containing cavity 13 and a plurality of air outlets 111 communicating with the air-containing cavity 13. The decorative part 2 is provided with annular ribs 21 surrounding the plurality of air outlets 111. The decorative part 2, the annular ribs 21 and the box body 1 together form the diffused cavity 211. The decorative part 2 is provided with a plurality of diffused holes 22 communicating with the diffused cavity 211, and the number of diffused holes 22 is greater than the number of air outlets 111.

[0055] When the control terminal with the silencer diffusion gas box of this application is working, the oxygen produced by the oxygen generator enters the gas chamber 13 through the air inlet, so that the oxygen diffuses in the gas chamber 13 and then enters the diffusion chamber 211 through the air outlet 111. The oxygen in the diffusion chamber 211 diffuses again and is released into the room through the diffusion hole 22, so as to realize the release of the oxygen produced by the oxygen generator into the room by diffusion.

[0056] Because oxygen undergoes multiple diffusion processes when released into the room through diffusion, the kinetic energy of oxygen as it exits through diffusion holes 22 is greatly reduced, thereby significantly reducing the noise generated when the silencer diffusion box diffuses and releases oxygen, and thus greatly improving the user experience.

[0057] Furthermore, since the number of diffusion holes 22 is greater than the number of air outlet holes 111, the oxygen in the diffusion chamber 211 is released through multiple diffusion holes 22, which greatly improves the diffusion effect of the silencer diffusion air box on oxygen, thereby further improving the user experience.

[0058] In addition, by setting the decorative part 2, the air outlet 111 can be blocked by the decorative part 2 to improve the appearance quality of the silencer diffuser box.

[0059] Preferably, the diameter of the vent 111 is larger than the diameter of the diffusion vent 22 to ensure the efficiency of oxygen entering the diffusion chamber 211, thereby ensuring the diffusion effect of the silencer diffusion box on oxygen.

[0060] This application does not specify the connection method between the annular rib 21 and the box body 1. Preferably, refer to... Figure 3 and Figure 4 The outer side of the box body 1 is provided with connecting ribs 115 surrounding multiple air vents 111. One of the connecting ribs 115 and the annular ribs 21 is provided with a sealing groove 116, and the other is provided with a sealing rib 221 extending into the sealing groove 116.

[0061] It is understandable that the connecting rib 115 and the annular rib 21 are arranged opposite each other so that the annular rib 21 can be mated and cooperate with the connecting rib 115.

[0062] Because the outer side of the box 1 is provided with connecting ribs 115 surrounding multiple air outlets 111, the volume of the diffusion cavity 211 is further increased, so as to further reduce the kinetic energy of oxygen when it is discharged through the diffusion holes 22, thereby further improving the noise reduction effect of the noise reduction diffusion box.

[0063] Furthermore, since one of the connecting rib 115 and the annular rib 21 is provided with a sealing groove 116, and the other is provided with a sealing rib 221 extending into the sealing groove 116, on the one hand, the cooperation between the sealing rib 221 and the sealing groove 116 can position the decorative part 2 and the box body 1, thereby reducing the difficulty of assembling the decorative part 2 and the box body 1 together, improving the assembly efficiency of the silencing diffuser box, and thus reducing the assembly cost of the silencing diffuser box. On the other hand, the cooperation between the sealing groove 116 and the sealing rib 221 can also increase the connection sealing between the connecting rib 115 and the annular rib 21, so as to ensure the airtightness of the diffuser cavity 211.

[0064] It should be noted that, in order to increase the connection stability between the decorative part 2 and the box body 1, when assembling the decorative part 2 onto the box body 1, it is necessary to apply glue to the sealing groove 116 in advance, so as to use the glue to fix the sealing rib 221 to the groove wall of the sealing groove 116 together, thereby increasing the connection stability between the decorative part 2 and the box body 1.

[0065] Specifically, the sealing groove 116 is provided on the end face of the connecting rib 115 facing the decorative part 2 and extends continuously along the circumference of the connecting rib 115, and the sealing rib 221 is provided on the end face of the annular rib 21 facing the box body 1 and extends continuously along the circumference of the annular rib 21.

[0066] In other embodiments, the annular rib 21 can be directly fixed to the end face of the box body 1 facing the decorative part 2 using glue; or, a groove for accommodating the annular rib 21 can be provided on the end face of the box body 1 facing the decorative part 2, so that the end of the annular rib 21 away from the decorative part 2 is inserted into the groove and the annular rib 21 is fixedly connected to the groove wall using glue.

[0067] In a preferred embodiment, refer to Figure 1 and Figure 2 The box body 1 has an air inlet end and an air outlet end. At least one side of the air outlet end is recessed into the interior of the box body 1 and a clearance notch 14 is provided. Multiple air outlet holes 111 are provided on the wall surface of the clearance notch 14.

[0068] Since multiple air vents 111 are located on the wall of the clearance notch 14, after the decorative part 2 is assembled into the box body 1, the annular rib 21 can be located in the clearance notch 14 to reduce the volume of the sound-absorbing diffuser box, thereby achieving the effect of facilitating the miniaturization design of the sound-absorbing diffuser box.

[0069] The better one is to refer to Figure 1 and Figure 2 The box body 1 has clearance notches 14 on both sides of the air outlet end. Multiple air outlets 111 are located on the wall of one of the clearance notches 14, so that one side of the box body 1 avoids the annular rib 21, and the clearance notch 14 on the other side of the box body 1 avoids other components inside the control terminal, so as to facilitate the miniaturization design of the control terminal.

[0070] Of course, in other embodiments, the design of the avoidance notch 14 can be omitted so that the appearance of the box 1 is more regular.

[0071] This application does not specifically limit the structure of box 1; preferably, refer to... Figures 1 to 3 The box body 1 includes a first outer shell 11 and a second outer shell 12 that together form an air cavity 13. The air cavity 13 is provided with multiple partitions for dividing the air cavity 13 into multiple buffer chambers. Each partition forms a communication port with the cavity wall of the air cavity 13, and two adjacent communication ports are staggered.

[0072] Since the box body 1 includes a first outer shell 11 and a second outer shell 12 that together form the air cavity 13, the production difficulty of the box body 1 is reduced, thereby reducing the yield of the box body 1 and thus reducing the production cost of the box body 1.

[0073] Furthermore, since each partition forms a communication port with the cavity wall of the gas chamber 13, and adjacent communication ports are staggered, this increases the movement path of oxygen in the gas chamber 13, thereby increasing the kinetic energy consumption of oxygen flowing in the gas chamber 13, further reducing the kinetic energy of oxygen when it is discharged through the diffusion hole 22, and thus further improving the noise reduction effect of the silencer diffusion gas box. On the other hand, it increases the number of times oxygen diffuses in the gas chamber 13, further reducing the kinetic energy of oxygen, and thus further improving the noise reduction effect of the silencer diffusion gas box.

[0074] It should be noted that, in addition to being formed between the partition and the cavity wall of the air chamber 13, the connection port can also be formed by a hole structure pre-reserved on the partition.

[0075] In this embodiment, the location of the multiple air outlets 111 and the air inlets is not specifically limited. Both can be located on the first housing 11 or on the second housing 12. The accompanying drawings of this application show that the multiple air outlets 111 and the air inlets are located on the first housing 11.

[0076] This application does not specify the particular arrangement of multiple buffer cavities; preferably, refer to... Figure 2 The box body 1 has a length direction, and multiple buffer chambers are arranged sequentially along the length direction of the box body 1. The air inlet is connected to the buffer chamber located at one end of the length direction of the box body 1, and multiple air outlets 111 are all connected to the buffer chamber located at the other end of the length direction of the box body 1.

[0077] Because multiple buffer chambers are arranged sequentially along the length of the box 1, the distribution of buffer chambers inside the box 1 is more regular, thereby further reducing the manufacturing difficulty of the box 1; because the air inlet is connected to the buffer chamber located at one end of the length of the box 1, and multiple air outlets 111 are all connected to the buffer chamber located at the other end of the length of the box 1, the oxygen can pass through multiple buffer chambers sequentially when flowing in the gas chamber 13, so as to ensure the movement path of the oxygen in the gas chamber 13, thereby ensuring the consumption effect of oxygen kinetic energy, and thus ensuring the noise reduction effect of the silencer diffuser box.

[0078] This application does not specify a particular structure for the partition; however, preferred options are described below. Figure 3 , Figure 6 and Figure 7The partition includes a first partition 15 disposed on the first outer shell 11 and a second partition 16 disposed on the second outer shell 12. The first partition 15 and the second partition 16 are disposed opposite to each other. The communication port includes a first communication port 151 and a second communication port 161 that is staggered with the first communication port 151 in the length direction of the box body 1. One of the two adjacent first partitions 15 forms a first communication port 151 between the first partition 15 and the cavity wall of the air cavity 13. One of the two adjacent second partitions 16 forms a second communication port 161 between the second partition 16 and the cavity wall of the air cavity 13.

[0079] It should be noted that the relative arrangement of the first partition 15 and the second partition 16 mentioned above means that after the first outer shell 11 and the second outer shell 12 are assembled together, the first partition 15 and the second partition 16 are arranged in a one-to-one correspondence, and the first partition 15 and its corresponding second partition 16 abut against each other.

[0080] Since the first connecting port 151 and the second connecting port 161 are staggered along the length of the box body 1, and one of the two adjacent first partitions 15 forms a first connecting port 151 with the cavity wall of the gas chamber 13, and one of the two adjacent second partitions 16 forms a second connecting port 161 with the cavity wall of the gas chamber 13, the movement path of oxygen in the gas chamber 13 is further increased, thereby further improving the kinetic energy consumption of oxygen in the gas chamber 13. This further reduces the kinetic energy of oxygen when it is discharged from the diffusion cavity 211 through the diffusion hole 22, thereby further improving the noise reduction effect of the silencer diffusion gas box and further improving the user experience.

[0081] Preferably, the first connecting port 151 is formed by the gap between the top of the first partition 15 and the top wall of the gas cavity 13, and the second connecting port 161 is formed by the gap between the bottom of the second partition 16 and the bottom wall of the gas cavity 13, so as to further increase the movement path of oxygen in the gas cavity 13, thereby further improving the consumption effect of oxygen kinetic energy, and further improving the noise reduction effect of the silencer diffuser.

[0082] In other implementation examples, the partition can also be an integral structure, with the partition disposed in the first housing 11 or the second housing 12, and the partition protruding from the first housing 11 or the second housing 12 to which it is attached, so that after the first housing 11 and the second housing 12 are assembled together, the partition extends into the second housing 12 or the first housing 11.

[0083] In other embodiments, the multiple buffer cavities may be arranged sequentially along the circumference of the box body 1, or the multiple buffer cavities may be divided into two rows, with the two rows of buffer cavities staggered along the length of the box body 1.

[0084] This application does not specify the connection method between the first outer shell 11 and the second outer shell 12. Preferably, refer to... Figure 3 , Figure 6 and Figure 7 The first outer shell 11 has a first mating surface facing the second outer shell 12, and the second outer shell 12 has a second mating surface facing the first outer shell 11. One of the first mating surface and the second mating surface is provided with a positioning groove 117, and the other of the two is provided with a positioning rib 121 extending into the positioning groove 117.

[0085] Since one of the first mating surface and the second mating surface is provided with a positioning groove 117, and the other of the two is provided with a positioning rib 121 extending into the positioning groove 117, on the one hand, the positioning rib 121 and the positioning groove 117 can be used to limit the first outer shell 11 and the second outer shell 12, thereby reducing the difficulty of assembling the first outer shell 11 and the second outer shell 12 together and improving the assembly efficiency of the box 1. On the other hand, the cooperation between the positioning rib 121 and the positioning groove 117 can also increase the sealing between the first outer shell 11 and the second outer shell 12, so as to ensure the airtightness of the air chamber 13.

[0086] Specifically, the positioning groove 117 is provided on the first mating surface and extends continuously along the circumference of the first outer shell 11, and the positioning rib 121 is provided on the second mating surface and extends continuously along the circumference of the second outer shell 12.

[0087] It should be noted that, in order to increase the connection stability of the first outer shell 11 and the second outer shell 12, when assembling the first outer shell 11 and the second outer shell 12, it is necessary to apply glue to the positioning groove 117 in advance, so as to use the glue to fix the positioning rib 121 to the groove wall of the positioning groove 117, thereby increasing the connection stability of the first outer shell 11 and the second outer shell 12.

[0088] In other embodiments, the housing 1 may also include an outer shell with an opening and a cover disposed at the opening.

[0089] In a preferred embodiment, the air chamber 13 is filled with noise-reducing cotton so that the oxygen entering the air chamber 13 through the air inlet moves inside the noise-reducing cotton and is eventually discharged through the air outlet 111.

[0090] Because the air chamber 13 is filled with noise-reducing cotton, the oxygen entering the air chamber 13 moves inside the noise-reducing cotton, thereby reducing the noise generated by the contact friction between the oxygen flow and the cavity wall of the air chamber 13, and further improving the noise reduction effect of the silencer diffuser.

[0091] This application does not specifically limit the structure of the noise-reducing cotton. Preferably, the noise-reducing cotton is a sponge to ensure the shape stability of the noise-reducing cotton, thereby ensuring the noise reduction effect of the sound-absorbing and diffusing air box. In other embodiments, the noise-reducing cotton can also be cotton wool, mixed fiber cotton, or other materials with noise-reducing properties.

[0092] In a preferred embodiment, refer to Figure 1 and Figure 2 An air inlet 112 extends outward from the air inlet, and an air inlet pipe 113 is connected to the air inlet 112. An regulating valve 114 is installed in the air inlet pipe 113.

[0093] Because an air inlet nozzle 112 extends outward from the air inlet, it facilitates the connection between the air inlet pipe 113 and the air inlet, thereby reducing the assembly difficulty of the control terminal. Because a regulating valve 114 is provided in the air inlet pipe 113, the oxygen flow rate and pressure in the input gas chamber 13 can be regulated by the regulating valve 114 to reduce the pressure of oxygen entering the gas chamber 13, thereby further improving the noise reduction effect on the silencer diffuser box.

[0094] This application does not specifically limit the structure of the regulating valve 114. Preferably, the regulating valve 114 is a throttle orifice valve to ensure the regulation effect on oxygen flow and pressure. In other embodiments, the regulating valve 114 can also be a needle valve or other structures capable of regulating flow and pressure.

[0095] Preferably, the outer side of the air inlet 112 away from the air chamber 13 is provided with a boss, and the diameter of the boss gradually decreases along the direction away from the air chamber 13. On the one hand, this facilitates the connection of the air inlet pipe 113 to the air inlet 112, and on the other hand, it increases the connection stability between the air inlet pipe 113 and the air inlet 112.

[0096] This application also discloses a control terminal for a diffusion oxygen generator, which includes a housing and a sound-absorbing diffusion gas box as described above, with the decorative part 2 integrally formed with the housing.

[0097] Because the control terminal uses the aforementioned silencer and diffused gas box, the noise generated during operation is reduced, and the oxygen diffusion effect is improved, thereby enhancing the user experience.

[0098] Furthermore, since the aforementioned silencing gas box is provided with an avoidance notch 14, the box body 1 can abut against the shell, thereby increasing the stability of the silencing gas box.

[0099] Of course, in addition to the above-disclosed configuration where the decorative part 2 is integrally formed with the housing, the decorative part 2 can also be separate from the housing. That is, the housing has mounting holes, and the decorative part 2 is located in the mounting holes.

[0100] Since the housing has mounting holes, the decorative part 2 is located in the mounting holes, which reduces the difficulty of producing the housing and thus reduces the production cost of the housing.

[0101] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0102] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0103] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
