[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] Embodiment 1:

[0032] See also Figure 1-Figure 4 As shown, an air mattress equipped with a knob-type joint comprises:

[0033] The air mattress body 1 has an air inlet at a position near a corner of the top outer wall of the air mattress body 1;

[0034] The joint mechanism 3 is plugged into the inner circumferential wall of the air inlet;

[0035] A fixed frame 4, the fixed frame 4 is fixedly mounted on the bottom inner wall of the air mattress body 1;

[0036] The gas introduction mechanism 5 is installed on the surface of the fixed frame 4 , and one end of the gas introduction mechanism 5 is connected to one end of the joint mechanism 3 .

[0037] As can be seen from the above, the device ventilates the internal gas introduction mechanism 5 through the joint mechanism 3. Under the support of the fixed frame 4, the gas introduction mechanism 5 expands and stretches the entire air mattress body 1, so that the air mattress body 1 is unfolded into a stable fixed shape, which is convenient for the patient to lie on its surface. The joint mechanism 3 has a good sealing effect, which can avoid internal air leakage of the air mattress body 1, so that the air mattress body 1 remains in a filled state. Existing devices mostly use plug-in methods to fix the trachea, and the plug-in trachea is easy to fall off, resulting in leakage, which in turn affects the use of the air mattress body 1. The present device fixes the trachea through the joint mechanism 3 to reduce the occurrence of tracheal falling off.

[0038] Specifically, the joint mechanism 3 includes a bent joint 301, which is fixedly inserted on the circumferential inner wall of the air inlet, and the circumferential outer wall of the bent joint 301 is fitted on the surface of the air mattress body 1 and is sleeved with a sealing gasket 2 304, and the surface of the sealing gasket 2 304 is fitted on the outer wall of the bent joint 301 and is bonded with a sealing tape 303.

[0039] As can be seen from the above, the bent joint 301 is provided to facilitate the introduction of gas, and the bent joint 301 is fixed at a corner of the air mattress body 1, which will not affect the placement and fixation of the air mattress body 1, nor will it affect the patient's lying down. The sealing pad 304 and the sealing tape 303 are provided to strengthen the sealing of the connection between the bent joint 301 and the air mattress body 1, so that the sealing effect of the bent joint 301 is better, making it difficult for the air to leak inside the air mattress body 1.

[0040] Specifically, a threaded groove 305 is opened on the inner wall of the other end of the elbow joint 301, and a soft long tube 2 is threadedly connected to the inner wall of one side of the elbow joint 301 with the threaded groove 305. The circumferential outer wall of the soft long tube 2 is fitted on one end of the elbow joint 301 and is sleeved with a sealing gasket 302, and a solenoid valve is provided at one end of the soft long tube 2.

[0041] As can be seen from the above, the setting of the threaded groove 305 at one end of the elbow joint 301 allows the soft long tube 2 to be threadedly inserted and fixed on one end of the elbow joint 301, thereby enhancing the sealing of the connection between the elbow joint 301 and the soft long tube 2. Through the setting of the sealing gasket 302, the connection between the elbow joint 301 and the soft long tube 2 is further sealed to reduce the occurrence of air leakage.

[0042] Specifically, the gas introduction mechanism 5 includes an air chamber 2 502 and two air chambers 1 501 . The two air chambers 1 501 are installed on the surface of the fixed frame 4 near the two sides, and the air chamber 2 502 is installed in the middle of the surface of the fixed frame 4 .

[0043] As can be seen from the above, after ventilation is introduced into the interior of the air mattress body 1 through the soft long tube 2 and the bent joint 301 through the provided air chamber 1 501 and the air chamber 2 502, the gas enters the air chamber 1 501 and the air chamber 2 502, causing the air chamber 1 501 and the air chamber 2 502 to expand, thereby expanding the entire air mattress body 1, thereby expanding the air mattress body 1 to facilitate the patient to lie down.

[0044] Specifically, the same connecting pipe 504 is horizontally inserted into one end of the air chamber 1 501 and the air chamber 2 502 , and an airway tube 503 is inserted into one end of the top outer wall of the connecting pipe 504 close to the elbow 301 , and one end of the airway tube 503 is inserted into one end of the elbow 301 .

[0045] As can be seen from the above, the gas introduced from the outside enters the air chamber 1 501 and the air chamber 2 502 through the bent joint 301, the airway tube 503 and the connecting tube 504, so that the air mattress body 1 is expanded, thereby making it easier for the patient to lie on the surface of the air mattress body 1.

[0046] Working principle: When in use, open the solenoid valve of the soft long tube 2, and let the gas pass into the soft long tube 2 through the air pump, and then pass the gas into the air chamber 1 501 and the air chamber 2 502 through the bent joint 301, the airway tube 503 and the connecting tube 504, so that the air mattress body 1 is stretched out, so that it is convenient for the patient to lie on the surface of the air mattress body 1, and then close the solenoid valve and remove the air pump. The interfaces at both ends of the bent joint 301 are respectively provided with a sealing gasket 1 302, a sealing gasket 2 304 and a sealing tape 303, which strengthens the sealing of the bent joint 301, reduces the discharge of gas, and makes the inside of the air mattress body 1 always in a filled state.

[0047] Embodiment 2:

[0048] refer to Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that a plurality of protrusion mechanisms 6 are provided on the top outer wall of the air mattress body 1, the protrusion mechanism 6 includes a massage pad 601, the massage pad 601 is bonded to the top outer wall of the air mattress body 1, and a plurality of massage protrusions 602 are bonded to the top outer wall of the massage pad 601.

[0049] As can be seen from the above, the massage pad 601 and the massage protrusions 602 are arranged on the surface of the air mattress body 1. After the patient lies on the surface of the air mattress body 1, the massage pad 601 and the massage protrusions 602 can make the patient more comfortable.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
