Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a respirator that is easy to assemble and disassemble. Background Technology

[0002] A typical ventilator mask consists of a main body, eyebrow support, bend, bend cover, cushion, rubber stopper, retaining ring, buckle, forehead pad, and headband, and is intended for use by a single patient only.

[0003] A utility model patent with application number CN202120161457.6 proposes a respirator that is easy to assemble and disassemble. The respirator includes a main body, a breathing valve fixedly mounted on the front surface of the main body, and connecting devices symmetrically fixedly mounted on the outer surface of the main body. An antibacterial goggle, facilitating disassembly, is mounted on the upper surface of the main body. A connecting groove is symmetrically formed through the outer surface of the antibacterial goggle, and a second restraining strap is fixedly mounted within the connecting groove. To disassemble the main body and the restraining strap, the sleeve of the restraining strap is moved downwards to fully expose the inverted T-shaped groove. Then, the connecting rod is pressed downwards to move the positioning block downwards and disengage it from the fixed groove. The connecting rod is then rotated forward to release the restraining strap from the inverted T-shaped groove. The restraining strap can then be lifted upwards, and its sleeve disengagement from the groove of the connecting block completes the disassembly. The structure is simple, and disassembly and assembly are convenient and quick.

[0004] In the aforementioned patent, the device first presses down on the connecting rod to move the positioning block away from the fixing groove, thereby releasing the restraint strap's sleeve interface from the inverted T-shaped groove. During the use of the device, the connecting rod is easily accidentally touched, causing the restraint strap to separate from the main body of the breathing mask, which is inconvenient for the use of the mask and reduces the practicality of the device. Therefore, a breathing mask that is easy to assemble and disassemble is provided to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a respirator that is easy to assemble and disassemble, thereby solving the problems mentioned in the background section.

[0006] The device first presses down on the connecting rod to move the positioning block away from the fixing groove, so that the connecting rod and the positioning block are separated from the inverted T-shaped groove and the restraint strap's sleeve interface is released. During the use of the device, the connecting rod is easily accidentally touched, causing the restraint strap to separate from the breathing mask body, which is inconvenient for the use of the mask and reduces the practicality of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A respirator that is easy to assemble and disassemble includes a respirator body. A restraint strap is provided on one side of the respirator body. A first connecting block is symmetrically fixedly connected to the outer side of the restraint strap. A second connecting block is symmetrically fixedly connected to the outer side of the respirator body. The first connecting block has a second sliding groove inside that cooperates with the second connecting block. When separating the respirator body and the restraint strap, sliding a pull block inside the first sliding groove moves a slider upwards, causing the slider to compress a telescopic spring. This pulls the first connecting block, causing a locking block to move out of the locking groove. This prevents accidental contact with the slider that could separate the respirator body from the restraint strap, facilitating the use of the respirator body.

[0009] Preferably, a locking block is fixedly connected inside the second slide groove, and a fourth slide groove is opened inside the second connecting block. A slider is slidably connected inside the fourth slide groove, and a slot for cooperating with the locking block is opened inside the slider. Pulling the first connecting block causes the locking block to move out of the slot, which can prevent accidental contact with the slider from separating the breathing mask body from the restraint strap.

[0010] Preferably, the second connecting block has symmetrically formed limiting grooves inside, and a limiting block is slidably connected inside the limiting groove. The limiting block is fixedly connected to the slider, which facilitates limiting the slider and prevents the slider from deviating during movement.

[0011] Preferably, the slider has a third groove inside, and a telescopic spring is fixedly connected inside the third groove. The telescopic spring is fixedly connected to the second connecting block, and the slider limits and fixes the block inside the groove under the elastic force of the telescopic spring.

[0012] Preferably, a breathing valve is fixedly connected inside the main body of the breathing mask to facilitate the use of the main body of the breathing mask.

[0013] Preferably, a pull block is fixedly connected to one side of the slider, and a first groove is opened inside the first connecting block to cooperate with the pull block. The pull block drives the slider to move upward, so that the slider compresses the telescopic spring.

[0014] This invention provides a breathing mask that is easy to assemble and disassemble. Compared with the prior art, it has the following advantages:

[0015] Beneficial effects:

[0016] This easy-to-assemble breathing mask, through the arrangement of a locking block, a slider, and a telescopic spring, can push the first connecting block to allow the second connecting block to enter the interior of the second sliding groove. The locking block enters the interior of the locking groove, and the slider, under the elastic force of the telescopic spring, limits and fixes the locking block, which can prevent accidental contact with the slider from separating the breathing mask body from the restraint strap, making the breathing mask body easier to use and improving the practicality of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a respirator that is easy to assemble and disassemble, including a respirator body 1, a restraint strap 2 on one side of the respirator body 1, a first connecting block 3 symmetrically fixedly connected to the outer side of the restraint strap 2, and a second connecting block 9 symmetrically fixedly connected to the outer side of the respirator body 1. The first connecting block 3 has a second sliding groove 6 that works with the second connecting block 9. When separating the respirator body 1 and the restraint strap 2, the pull block 5 inside the first sliding groove 4 is slid, and the pull block 5 drives the slider 8 to move upward, so that the slider 8 squeezes the telescopic spring 14, which can pull the first connecting block 3 to move the locking block 7 out of the locking groove 13. This can prevent accidental contact with the slider 8 and separation of the respirator body 1 from the restraint strap 2, making it convenient to use the respirator body 1.

[0023] Furthermore, a locking block 7 is fixedly connected inside the second slide groove 6, and a fourth slide groove 11 is opened inside the second connecting block 9. A slider 8 is slidably connected inside the fourth slide groove 11, and a locking groove 13 is opened inside the slider 8 to cooperate with the locking block 7. Pulling the first connecting block 3 will cause the locking block 7 to move out of the locking groove 13, which can prevent accidental contact with the slider 8 and separation of the breathing mask body 1 from the restraint strap 2.

[0024] Furthermore, the second connecting block 9 has symmetrically formed limiting grooves 15 inside, and a limiting block 12 is slidably connected inside the limiting groove 15. The limiting block 12 is fixedly connected to the slider 8, which facilitates limiting the slider 8 and prevents the slider 8 from deviating during movement.

[0025] Furthermore, a third slide groove 10 is provided inside the slider 8, and a telescopic spring 14 is fixedly connected inside the third slide groove 10. The telescopic spring 14 is fixedly connected to the second connecting block 9, and the slider 8 limits and fixes the card block 7 inside the card groove 13 under the elastic force of the telescopic spring 14.

[0026] Furthermore, a breathing valve 16 is fixedly connected inside the breathing mask body 1 to facilitate the use of the breathing mask body 1.

[0027] Furthermore, a pull block 5 is fixedly connected to one side of the slider 8, and a first groove 4 is provided inside the first connecting block 3 to cooperate with the pull block 5. The pull block 5 drives the slider 8 to move upward, so that the slider 8 compresses the telescopic spring 14.

[0028] During operation, when disassembling the breathing mask body 1 and the restraint strap 2, the pull block 5 inside the first slide groove 4 is slid. The pull block 5 moves the slider 8 upward, causing the slider 8 to compress the telescopic spring 14. This pulls the first connecting block 3, causing the locking block 7 to move out of the slot 13. This prevents accidental contact with the slider 8 that could separate the breathing mask body 1 from the restraint strap 2, facilitating the use of the breathing mask body 1. During installation, the first connecting block 3 is pressed and moved, causing the second connecting block 9 to enter the second slide groove 6. At the same time, the locking block 7 enters the slot 13 inside the slider 8. Under the elastic force of the telescopic spring 14, the slider 8 limits and fixes the locking block 7 inside the slot 13, facilitating the disassembly of the breathing mask body 1 and the restraint strap 2 for cleaning and disinfection, making the cleaning and disinfection more thorough and the disinfection effect better.
