[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] This utility model embodiment provides a humidifier, such as Figures 1 to 3 As shown, the device includes a housing 10 and a humidification assembly 20. The housing 10 forms a receiving cavity with a first opening 101 and a second opening 102. The humidification assembly 20 includes absorbent cotton 210 and a support tube 220 sleeved inside the absorbent cotton 210. The humidification assembly 20 is disposed vertically in the receiving cavity. The support tube 220 communicates with the first opening 101, and multiple sets of vent holes 201 are formed on the side wall of the support tube 220. The vent holes 201 are used to connect the support tube 220 with the receiving cavity.

[0026] When using the humidifier of this embodiment to humidify oxygen, water is stored inside the outer casing 10. The first opening 101 formed on the outer casing 10 is used to communicate with oxygen generating equipment such as an oxygen concentrator to deliver oxygen into the outer casing 10. A humidification component 20 is provided inside the outer casing 10. The humidification component 20 is arranged vertically in the receiving cavity. The humidification component 20 includes absorbent cotton 210 and a support tube 220 sleeved inside the absorbent cotton 210. Oxygen enters the support tube 220 through the first opening 101, and passes through the vent 201 and the absorbent cotton 210 into the receiving cavity. Oxygen is output through the second opening 102 within the cavity to humidify it. The aforementioned support tube 220 provides support strength for the absorbent cotton 210. Under the support of the support tube 220, the stability of the absorbent cotton 210 within the cavity is ensured. During long-term use, even if the absorbent cotton 210 is immersed in water for a long time to humidify the oxygen, it will not soften or fall out of the outer shell 10 under the support of the support tube 220, thus ensuring the stability of the absorbent cotton 210 within the cavity and guaranteeing the humidification effect of the oxygen.

[0027] In practical applications, water is injected into the bottom of the outer shell 10. The absorbent cotton 210 has strong water absorption and breathability. When the bottom of the absorbent cotton 210 is immersed in water, the water can be drawn to the top, thus humidifying the oxygen passing through the absorbent cotton 210.

[0028] As a preferred embodiment, the end of the absorbent cotton 210 that is away from the first opening 101 is the first closed end 211, and the end of the support tube 220 that is away from the first opening 101 is the second closed end. The second closed end of the support tube 220 abuts against the first closed end 211.

[0029] The first closed end 211 increases the contact area between the absorbent cotton 210 and the outer shell 10, improving the stability of the absorbent cotton 210 within the outer shell 10. The second closed end increases the contact area between the support tube 220 and the absorbent cotton 210, improving the connection stability between the two and ensuring the support stability of the support tube 220 on the absorbent cotton 210. This further strengthens the stability of the absorbent cotton 210 within the outer shell 10, ensuring the humidification effect of oxygen.

[0030] In a preferred embodiment, the outer shell 10 includes a first shell 110 and a second shell 120, which together form a receiving cavity. The first shell 110 has a first opening 101 and a second opening 102 at one end away from the second shell 120. An annular fixing platform 111 is provided inside the first shell 110. A first connecting pipe 112 is provided at the first opening 101. The first connecting pipe 112 is located outside the first shell 110, and a portion of the first connecting pipe 112 extends into the receiving cavity and is located inside the annular fixing platform 111, forming an annular mounting space 103 between the first connecting pipe 112 and the annular fixing platform 111. A water-absorbing cotton 210 is inserted into the annular mounting space 103. A support pipe 220 abuts against the end of the first connecting pipe 112 and communicates with the first connecting pipe 112. A second connecting pipe 113 is provided at the second opening 102. The second connecting pipe 113 is located outside the first shell 110 and communicates with the receiving cavity.

[0031] The outer shell 10 is formed by combining a first shell 110 and a second shell 120. This structure facilitates the installation of the humidification component 20 and the injection of water, making operation convenient. The first shell 110 and the second shell 120 enclose the aforementioned receiving cavity. In this embodiment, during use, the first shell 110 is located on top and the second shell 120 is located below. The top of the first shell 110 has the aforementioned first opening 101 and second opening 102. More specifically, an annular fixing platform 111 is provided inside the first shell 110, and a first connecting pipe 112 is provided at the first opening 101. The first connecting pipe 112 is located outside the first shell 110, and the arrangement of the first connecting pipe 112 facilitates... The humidification assembly 20 is connected to an external oxygen generator to introduce oxygen into the housing 10. Simultaneously, a portion of the first connecting pipe 112 extends into the receiving cavity, forming an annular mounting space 103 between it and the annular fixing platform 111. Absorbent cotton 210 is inserted into the annular mounting space 103, securing one end of the absorbent cotton 210 firmly to the first housing 110, ensuring the stability of the absorbent cotton 210 within the receiving cavity. Meanwhile, a support pipe 220 abuts against the end of the first connecting pipe 112, providing stable support and further enhancing the stability of the humidification assembly 20 within the housing 10. Oxygen from the external oxygen generator is delivered to the support pipe 220 via the first connecting pipe 112. A second connecting pipe 113 is located at the second opening 102, outside the first housing 110, to facilitate the delivery of humidified oxygen to the user. The aforementioned first connecting pipe 112 and second connecting pipe 113 improve the convenience and sealing of oxygen delivery, ensuring delivery efficiency.

[0032] As a preferred embodiment, multiple sets of vent holes 201 are spaced apart on the support tube 220 along the length direction of the support tube 220. Each set of vent holes 201 includes a first vent hole 2011 and a second vent hole 2012 located at both radial ends of the support tube 220. The first vent hole 2011 and the second vent hole 2012 are both used to connect the support tube 220 with the receiving cavity.

[0033] Multiple sets of vent holes 201 are distributed along the length of the support pipe 220, so that oxygen entering the outer shell 10 can be output through different vent holes 201 and contact the absorbent cotton 210, thereby improving the humidification efficiency of oxygen. The number of vent holes 201 is generally proportional to the vertical height of the support pipe 220. This embodiment is attached... Figure 2 The example given shows four sets of ventilation holes 201. More specifically, the ventilation holes 201 include a first vent 2011 and a second vent 2012 located at both ends of the support tube 220 in the radial direction. Oxygen can simultaneously come into contact with the absorbent cotton 210 along the first vent 2011 and the second vent 2012 to wet it, thereby further improving the humidification efficiency of the oxygen.

[0034] In this embodiment, refer to Figure 3 The first housing 110 and the second housing 120 are detachably connected, facilitating the use of the humidification bottle. For example, it allows for timely replenishment of water into the outer housing 10 to ensure humidification. More specifically, in achieving the detachable connection, the first housing 110 has an annular groove 104 at the end near the second housing 120, and the second housing 120 has an annular mounting part 122 at the end near the first housing 110. The annular mounting part 122 can be screwed into or out of the annular groove 104 to connect or separate the first housing 110 and the second housing 120. In this embodiment, the annular mounting part 122 and the annular groove 104 are threaded together, facilitating quick connection or separation of the first housing 110 and the second housing 120. The operation is convenient, and the connection stability is strong, making it easy for users to operate and use, which is beneficial for the use and promotion of the humidification bottle.

[0035] An external thread is formed on the outer wall of the annular mounting part 122, and an internal thread is formed on the inner wall of the annular groove 104 corresponding to the external thread. The threaded connection is achieved through the cooperation of the external and internal threads. The above-mentioned threaded connection can be a three-start thread, which makes the connection more reliable and easier to tighten the first housing 110 and the second housing 120, and is convenient for user operation.

[0036] Reference Figures 3 to 5 An annular limiting platform 124 is formed on the outer periphery of the second housing 120. When the annular mounting portion 122 extends into the annular groove 104, the end of the first housing 110 abuts against the annular limiting platform 124. This arrangement further enhances the connection stability between the first housing 110 and the second housing 120, facilitating the use and promotion of humidification bottles. A gear portion 125 is provided on the side of the annular limiting platform 124 near the annular mounting portion 122. A gear groove 114 matching the gear portion 125 is formed on the inner wall of the annular groove 104. When the first housing 110 and the second housing 120 are connected, the gear portion 125 meshes with the gear groove 114. This prevents them from twisting apart, improves the connection stability between the first housing 110 and the second housing 120, facilitates user operation, and promotes the use and promotion of humidification bottles. (Refer to...) Figure 4 and Figure 5 This embodiment provides an example of having two gear sections 125, located on opposite radial sides of the annular limiting platform 124. The number of gear slots 114 is the same as that of the gear sections 125, and they are arranged in a one-to-one correspondence. This arrangement improves the connection stability between the first housing 110 and the second housing 120.

[0037] As a preferred embodiment, a U-shaped notch 2211 is formed at the first closed end 211, and the U-shaped notch 2211 is connected to the first opening 101.

[0038] A U-shaped notch 2211 is formed at the first closed end 211 to increase the air flow rate at the end of the support tube 220 away from the first opening 101, thereby promoting the flow of oxygen in the support tube 220, increasing the flow rate of oxygen in the containment cavity, and improving the humidification efficiency of oxygen.

[0039] As a preferred embodiment, the second housing 120 has an annular mounting groove 121 formed at the end opposite to the first housing 110. The annular mounting groove 121 is located in the receiving cavity, and the first closed end 211 is located in the annular mounting groove 121.

[0040] The annular mounting groove 121 is used to fix the absorbent cotton 210. Placing the first closed end 211 in the annular mounting groove 121 can improve the stability of the absorbent cotton 210 in the outer shell 10.

[0041] As a preferred embodiment, a first notch 1211 is formed on the side wall of the annular mounting groove 121. The first notch 1211 communicates with the receiving cavity and extends to the bottom of the second housing 120.

[0042] As the humidifier operates, oxygen carries away the moisture inside the outer casing 10, causing the water level to drop. The first notch 1211 allows the water at the bottom of the outer casing 10 to be absorbed by the absorbent cotton 210 through the first notch 1211, thus making full use of the moisture at the bottom of the outer casing 10.

[0043] As a preferred embodiment, multiple first notches 1211 are provided and are evenly distributed on the annular mounting groove 121 along the circumference of the annular mounting groove 121.

[0044] The arrangement of the aforementioned multiple first notches 1211 is more conducive to the full contact between the absorbent cotton 210 and the moisture at the bottom of the outer shell 10, and this distribution will not affect the force on the absorbent cotton 210 in the annular mounting groove 121, thus ensuring the stability of the absorbent cotton 210 in the annular mounting groove 121.

[0045] As a preferred embodiment, the absorbent cotton 210, the support tube 220, and the outer shell 10 are arranged with their central axes collinear.

[0046] The aforementioned limitations on the absorbent cotton 210, support tube 220, and outer shell 10 improve the stability of the humidification component 20 within the outer shell 10 and ensure uniform oxygen flow within the outer shell 10, thereby enhancing the oxygen humidification effect.

[0047] This application also discloses an oxygen supply device, including the humidifier described in the foregoing embodiments. This oxygen supply device has the same structure and beneficial effects as the humidifier described in the foregoing embodiments. The structure and beneficial effects of the humidifier have been described in detail in the foregoing embodiments and will not be repeated here.
