DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] This embodiment provides an outlet connector with adjustable trigger sensitivity, which is in contact with the trigger component 1. Figure 1 and Figure 2As shown, it includes a connecting component 2, an air outlet component 3, an adjusting knob 4 and a sensitivity adjusting component 5; the connecting component 2 is provided with a accommodating cavity and an air inlet 21 and an air outlet 22 communicated with the accommodating cavity, the sensitivity adjusting component 5 is arranged in the accommodating cavity, and is provided with a first channel communicated with the air inlet 21 and the air outlet 22, one end of the sensitivity adjusting component 5 is matched and connected with the adjusting knob 4, and the other end is abutted with the trigger component 1; the air outlet component 3 is sleeved on the outer wall of the connecting component 2, and is provided with an air outlet channel 31 communicated with the air outlet 22; the adjusting knob 4 is rotated to make the sensitivity adjusting component 5 move in a direction close to or away from the adjusting knob 4, thereby correspondingly reducing or increasing the resistance of the sensitivity adjusting component 5 to the trigger component 1, so as to adjust the trigger sensitivity of the trigger component 1 during inhalation.

[0021] Specifically, in this embodiment, the principle and process of adjusting the trigger sensitivity of the trigger component 1 are as follows: Figure 4As shown, when the user does not inhale, the trigger component 1 will hinder the gas from entering the air inlet channel 25 (the figure does not specifically show how the trigger component 1 affects the gas entering the air inlet channel 25), and oxygen cannot be supplied at this time; when the user inhales, the negative pressure generated will produce an upward suction force on the trigger component 1, and the trigger component 1 is also subject to the downward resistance generated by the sensitivity adjustment component 5. At this time, it is necessary to coordinate the relationship between the suction force and the resistance, so that the user can suck up the trigger component 1 and the trigger sensitivity meets the breathing conditions, so that the gas can enter the air outlet connector through the air inlet channel 25, and finally provide pulse oxygen supply to the user; therefore, the adjustment of the trigger sensitivity is to adjust the relationship between the suction force and the resistance; if the resistance is small, the trigger component 1 is easy to be sucked up, then the sensitivity is high, and vice versa. In this embodiment, an adjustment knob 4 and a sensitivity adjustment component 5 are provided, wherein the sensitivity adjustment component 5 is in contact with the trigger component 1, generating resistance to the movement of the trigger component 1, and the resistance of the sensitivity adjustment component 5 to the trigger component 1 is controlled by the adjustment knob 4, thereby changing the trigger sensitivity of the trigger component 1, so that the user can adjust the trigger sensitivity according to his actual breathing situation, meet the oxygen supply triggering demand and save oxygen at the same time. The specific adjustment process is: when the user needs the trigger sensitivity of the trigger component 1 to be high, the adjustment knob 4 is rotated to make the sensitivity adjustment component 5 away from the trigger component 1, at this time, the resistance of the trigger component 1 is reduced, and it is easier for the user to inhale the trigger component 1; when the user needs the trigger sensitivity of the trigger component 1 to be low, the adjustment knob 4 is rotated to make the sensitivity adjustment component 5 close to the trigger component 1, at this time, the resistance of the trigger component 1 is large, and it is not easy for the user to inhale the trigger component 1; for example, for a user with weak breathing, the trigger component 1 can be set to a higher sensitivity accordingly, so that it can easily obtain oxygen supply; for a user with strong breathing, the trigger component 1 can be set to a lower sensitivity accordingly, so that it can obtain the oxygen supply that meets the demand and avoid gas waste.

[0022] In a specific embodiment, the sensitivity adjustment component 5 includes an adjustment rod 51 and an elastic component 52; one end of the adjustment rod 51 is clamped with the adjustment knob 4, and the other end is provided with a mounting groove for installing the elastic component 52, and the outer wall is provided with a first retaining ring A, and the elastic component 52 is arranged in the mounting groove and abuts against the trigger component 1; the side wall of the adjustment rod 51 close to the air outlet 22 is provided with a plurality of air outlet holes 511, and the air outlet holes 511 are connected to the air outlet 22.

[0023] In this embodiment, preferably, the elastic component 52 is a spring.

[0024] Specifically, the adjusting rod 51 is arranged in the accommodating cavity by a thread. When the adjusting knob 4 rotates, the adjusting rod 51 is driven to rotate synchronously therewith, thereby loosening or tightening the adjusting rod 51. When the adjusting rod 51 is in a tightened state, the elastic component 52 is in a compressed state in the mounting groove. In the process of loosening the adjusting rod 51, the adjusting rod 51 moves in a direction away from the trigger assembly 1 relative to the adjusting knob 4. At this time, the pressure of the adjusting rod 51 on the elastic component 52 is reduced, so the elastic force of the elastic component 52, that is, the resistance to the trigger assembly, is gradually reduced, and the operation of improving the trigger sensitivity is realized. Similarly, in the process of tightening the adjusting rod 51, the adjusting rod 51 moves in a direction close to the trigger assembly 1 relative to the adjusting knob 4. At this time, the pressure of the adjusting rod 51 on the elastic component 52 is increased, so the elastic force of the elastic component 52, that is, the resistance to the trigger assembly, is gradually increased, and the operation of reducing the trigger sensitivity is realized. In this embodiment, the adjusting rod 51 is limited by setting a first retaining ring A to prevent the adjusting rod 51 from being separated from the threaded area during the adjustment process, thereby ensuring that the subsequent adjustment of the trigger sensitivity is carried out smoothly.

[0025] In a specific embodiment, Figure 3 As shown, the adjusting knob 4 includes a fixing rod 41 and a limiting rod 42 arranged in the accommodating cavity; the fixing rod 41 is arranged at an end away from the adjusting rod 51, and the limiting rod 42 is arranged at an end close to the adjusting rod 51; the end of the connecting component 2 close to the fixing rod 41 is provided with a first groove, and the outer wall of the fixing rod 41 is provided with a protrusion, such as Figure 4 As shown, a second retaining ring B is provided between the first groove and the protrusion; a second groove for accommodating the limiting rod 42 is provided at one end of the adjusting rod 51 close to the limiting rod 42, and the limiting rod 42 is engaged with the adjusting rod 51 through the second groove, so that the adjusting rod 51 and the limiting rod 42 rotate synchronously.

[0026] In this embodiment, preferably, the limiting rod 42 is arranged at one end of the second groove and has a hexagonal prism structure, which can ensure that when the adjusting knob 4 rotates, the adjusting rod 51 rotates synchronously therewith. In practice, any structure that can ensure that the adjusting rod 51 rotates synchronously with the adjusting knob 4 can be adopted.

[0027] Specifically, the adjusting knob 4 is fixedly connected to the connecting component 2 in the axial direction via the second retaining ring B, while ensuring that the adjusting knob 4 can be rotated to any angle, thereby achieving flexible control of the adjusting rod 51 .

[0028] Specifically, in this embodiment, Figure 4 As shown, the adjustment knob 4 also includes an adjustment cover 43. The adjustment cover 43 is provided to facilitate the rotation of the adjustment knob 4, and the outer wall of the adjustment cover 43 is a concave-convex structure, which makes it more convenient for users to adjust by increasing friction.

[0029] In a specific embodiment, Figure 2 As shown, the gas outlet component 3 includes a gas outlet ring 32 and a gas outlet nozzle 33; the gas outlet ring 32 is sleeved on the outer wall of the connecting component 2, and the gas outlet nozzle 33 is arranged on the side wall of the gas outlet ring 32; the gas outlet channel 31 includes a gas storage tank 311 arranged on the inner wall of the gas outlet ring 32 all around and a second channel 312 arranged in the gas outlet nozzle 33, and the gas storage tank 311 and the second channel 312 are both connected to the gas outlet 22. Specifically, the arrangement of the gas storage tank 311 enables the gas to enter the second channel 312 more smoothly from the gas outlet 22, thereby ensuring smooth oxygen supply.

[0030] In a specific embodiment, Figure 2 As shown, the connecting component 2 includes a connecting cover 23 and a connecting ring 24. One end surface of the connecting cover 23 abuts against the trigger assembly 1 to form a first chamber. The other end surface of the connecting cover 23 is provided with the connecting ring 24, and the connecting ring 24 is provided with a second chamber connected to the first chamber. The air outlet 22 is provided on the side wall of the connecting ring 24. The outer wall of the connecting ring 24 near the end of the fixing rod 41 is provided with a third groove, as shown in FIG. Figure 4 As shown, a third retaining ring C is provided between the third groove and the air outlet ring 32 .

[0031] Specifically, the third retaining ring C is provided to limit the air outlet assembly 3 below the regulating cover 43, thereby limiting the axial movement of the air outlet assembly 3 and ensuring that it can rotate circumferentially at any angle to ensure smooth air outlet.

[0032] In this embodiment, a plurality of sealing rings (not shown) are provided between the connecting ring 24 and the air outlet ring 32, and between the connecting ring 24 and the adjusting rod 51, so as to avoid the loss and waste of gas during the oxygen supply process.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
