Description

Technical Field

[0001] This utility model relates to the field of inflatable cover technology, specifically a multifunctional inflatable cover for U-shaped pillows. Background Technology

[0002] As a key component of inflatable U-shaped pillows, the performance of the air cover directly affects the user experience. Currently, most U-shaped pillow air covers on the market only have basic inflation and deflation functions. During inflation, they are usually operated by pressing, and during deflation, the air is slowly released by opening the air valve.

[0003] This type of single-function inflatable cover has revealed many limitations in practical use. For example, when deflating, the existing inflatable cover can only allow the gas to escape freely by fully opening the air valve, and the deflation speed cannot be adjusted. If it is over-inflated, only a small amount needs to be released. Due to the lack of control over the deflation speed, it is easy to release too much gas, making air pressure adjustment very difficult. The only solution is to try to deflate and inflate repeatedly, which is cumbersome and difficult to achieve the desired effect. Therefore, a multi-functional inflatable cover for U-shaped pillows needs to be designed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional inflatable cover for U-shaped pillows to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional inflatable cover for a U-shaped pillow, comprising a U-shaped pillow body, an inflatable cover on the U-shaped pillow body, an exhaust component on one side of the inflatable cover, the exhaust component cooperating with a locking component, and adjusting the size of the exhaust port by a specified angle to adjust the deflation speed.

[0006] Preferably, the venting assembly includes a venting component and a ball valve body that are sealed and rotatably connected. Both have venting holes of the same specifications that communicate with the inner cavity of the U-shaped pillow body. The venting component is installed on one side of the inflation cover. The rotating rod of the ball valve body penetrates the venting component and cooperates with the locking component. By rotating the ball valve body, the two sets of venting holes are staggered at different angles, thereby adjusting the size of the venting hole opening and controlling the venting speed.

[0007] Preferably, the locking assembly includes a first limiting seat, a spring, a locking tongue, and a second limiting seat. The first limiting seat is installed on one side of the exhaust component. Three sets of springs are evenly distributed along the circumference of the ball valve body rotating rod on the first limiting seat. The free end of each set of springs is connected to a set of locking tongues. A set of second limiting seats is integrally formed on the outer wall of the ball valve body rotating rod. The locking tongue can be inserted into the limiting groove of the second limiting seat to achieve angle locking.

[0008] Preferably, an inflation component communicating with the inner cavity of the U-shaped pillow body is provided on the side of the inflation cover away from the exhaust component, for inflating the U-shaped pillow body.

[0009] Preferably, the inflation assembly includes an inflation channel, an air bladder, a one-way inlet valve, and a one-way outlet valve. A set of inflation channels is provided on the side of the inflation cover away from the exhaust component, and its inner cavity accommodates the air bladder. The one-way inlet valve, which communicates with the air bladder, is installed on the outer wall of the inflation channel, allowing only outside air to flow into the air bladder. The one-way outlet valve, which connects the air bladder and the inner cavity of the U-shaped pillow body, is installed on the side of the inner cavity of the inflation channel close to the U-shaped pillow body, so that when the air bladder is pressed, gas can only be injected into the U-shaped pillow body in one direction.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Compared with traditional air caps that can only fully open the air nozzle to release air, this multi-functional air cap can control the air release speed by adjusting the size of the exhaust port, avoiding difficulties in air pressure adjustment due to excessive air release, and can accurately achieve the ideal air pressure state. Unlike the past, there is no need to repeatedly inflate and deflate. One adjustment can basically meet the air pressure adjustment needs, greatly simplifying the operation process and saving time and effort.

[0012] 2. The three-group design of the locking component of this utility model can achieve three different angle fixation, such as closed, half-open, and fully open, corresponding to three different exhaust port opening sizes to meet different air release speed requirements. Compared with the traditional single air release method, it can more accurately adjust the air pressure and adapt to a variety of usage scenarios. The cooperation between the spring and the locking tongue ensures that the ball valve body can be firmly locked after the angle is adjusted, preventing changes in the exhaust port opening size due to shaking during use, ensuring stable air release speed, and improving the safety and reliability of the U-shaped pillow. Users only need to rotate the ball valve body to clearly feel the locking feedback of different gears and easily adjust to the appropriate air release speed. No complicated operation is required, reducing the threshold of use and improving the convenience of use.

[0013] 3. This utility model can achieve continuous inflation through simple pressing and releasing of the airbag, without complicated operation steps. The one-way air inlet valve and one-way air outlet valve ensure that the gas can only flow in one direction, effectively preventing gas leakage during inflation, ensuring the stability and sealing of the U-shaped pillow inflation, avoiding repeated inflation due to air leakage, and improving the user experience.

[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] Example 1

[0023] Please refer to Figure 1-6 As shown, this utility model provides a multifunctional inflatable cover for a U-shaped pillow, including a U-shaped pillow body 1, an inflatable cover 2 on the U-shaped pillow body 1, and an exhaust component on one side of the inflatable cover 2. The exhaust component cooperates with the locking component to change the size of the exhaust port by adjusting a specified angle, thereby adjusting the deflation speed.

[0024] When it is necessary to vent the U-shaped pillow body 1, the venting component is adjusted to cooperate with the locking component and rotate at a specified angle. As the rotation angle changes, the size of the vent will change accordingly. The larger the angle, the larger the vent and the faster the venting speed; the smaller the angle, the smaller the vent and the slower the venting speed, thus achieving precise adjustment of the venting speed.

[0025] Compared to traditional air caps that can only fully open the valve to release air, this multi-functional air cap allows for control of the release speed by adjusting the size of the vent. This avoids difficulties in adjusting air pressure due to excessive release, and can accurately achieve the ideal air pressure state. Unlike the past, there is no need to repeatedly inflate and deflate. One adjustment can basically meet the air pressure adjustment needs, greatly simplifying the operation process and saving time and effort.

[0026] Specifically, the exhaust assembly includes an exhaust component 3 and a ball valve body 4, both of which are provided with exhaust holes 5 of the same specifications that communicate with the inner cavity of the U-shaped pillow body 1. The exhaust component 3 is installed on one side of the inflation cover 2. The rotating rod of the ball valve body 4 penetrates the exhaust component 3 and cooperates with the locking assembly. By rotating the ball valve body 4, the two sets of exhaust holes 5 are staggered at different angles, thereby adjusting the opening size of the exhaust holes 5 and controlling the air release speed. The locking assembly includes a first limiting seat 6, a spring 7, a locking tongue 8, and a second limiting seat 9. The first limiting seat 6 is installed on one side of the exhaust component 3. The first limiting seat 6 has three sets of springs 7 evenly distributed along the circumference of the rotating rod of the ball valve body 4. The free end of each set of springs 7 is connected to a locking tongue 8. A second limiting seat 9 is integrally formed on the outer wall of the rotating rod of the ball valve body 4. The locking tongue 8 can be inserted into the limiting groove of the second limiting seat 9 to achieve angle locking.

[0027] When air needs to be released, the ball valve body 4 is rotated, and its rotating rod penetrates the exhaust component 3. Since both the exhaust component 3 and the ball valve body 4 are provided with exhaust holes 5 of the same specifications that are interconnected with the inner cavity of the U-shaped pillow body 1, as the ball valve body 4 rotates, the two sets of exhaust holes 5 are staggered at different angles. The larger the angle, the smaller the overlap, the smaller the opening of the exhaust hole 5, and the slower the air release speed; conversely, the larger the opening, the faster the air release speed. When rotated to the required angle, the second limiting seat 9 on the rotating rod of the ball valve body 4 will cooperate with the locking tongue 8 on the first limiting seat 6. The first limiting seat 6 is evenly distributed with three sets of springs 7 and locking tongues 8 along the circumference of the rotating rod of the ball valve body 4. The springs 7 push the locking tongue 8 into the limiting groove of the second limiting seat 9, locking the ball valve body 4 at one of the three different angles, thereby fixing the opening size of the exhaust hole 5 and achieving stable air release speed control.

[0028] The locking assembly features a three-stage design, allowing for three different angles of fixation: closed, half-open, and fully open. These correspond to three different vent opening sizes, satisfying varying venting speed requirements. Compared to traditional single venting methods, this design offers more precise air pressure adjustment, adapting to various usage scenarios. The cooperation between spring 7 and locking tongue 8 ensures that the ball valve body 4 is securely locked after the angle is adjusted, preventing changes in the vent opening size due to shaking during use. This ensures stable venting speed and enhances the safety and reliability of the U-shaped pillow. Users can easily adjust to the appropriate venting speed by simply rotating the ball valve body 4, feeling the locking feedback at different settings without complicated operations. This reduces the barrier to entry and improves ease of use.

[0029] The inflation cover 2 has an inflation assembly on the side away from the exhaust component 3, which communicates with the inner cavity of the U-shaped pillow body 1. This assembly is used to inflate the U-shaped pillow body 1. The inflation assembly includes an inflation channel 10, an airbag 11, a one-way inlet valve 12, and a one-way outlet valve 13. An inflation channel 10 is provided on the side of the inflation cover 2 away from the exhaust component 3. The inner cavity of the inflation channel 10 accommodates the airbag 11. A one-way inlet valve 12, which communicates with the airbag 11, is installed on the outer wall of the inflation channel 10, allowing only outside air to flow into the airbag 11. A one-way outlet valve 13, which connects the airbag 11 and the inner cavity of the U-shaped pillow body 1, is installed on the side of the inner cavity of the inflation channel 10 closest to the U-shaped pillow body 1. When the airbag 11 is pressed, gas can only be injected into the U-shaped pillow body 1 in one direction.

[0030] When the U-shaped pillow body 1 needs to be inflated, the air bladder 11 is squeezed, the internal space of the air bladder 11 decreases, and the air pressure increases. At this time, the one-way exhaust valve 13 opens and the one-way intake valve 12 closes. Under the action of pressure, the gas in the air bladder 11 enters the inner cavity of the U-shaped pillow body 1 through the one-way exhaust valve 13 and along the inflation channel 10, completing one inflation action. After releasing the air bladder 11, the air bladder 11 returns to its original shape, the internal air pressure decreases, the one-way intake valve 12 opens, and the outside air enters the air bladder 11 through the one-way intake valve 12 under the action of atmospheric pressure, preparing for the next inflation. This cycle is repeated to achieve continuous inflation of the U-shaped pillow body 1.

[0031] Continuous inflation can be achieved by simply pressing and releasing the airbag 11, without complicated operating steps. The one-way air inlet valve 12 and one-way air outlet valve 13 ensure that the gas can only flow in one direction, effectively preventing gas leakage during inflation, ensuring the stability and sealing of the U-shaped pillow inflation, avoiding repeated inflation due to air leakage, and improving the user experience.

[0032] Working principle: When air release is required, the ball valve body 4 is rotated, and its rotating rod penetrates the exhaust component 3. Since both the exhaust component 3 and the ball valve body 4 are equipped with exhaust holes 5 of the same specifications that communicate with the inner cavity of the U-shaped pillow body 1, as the ball valve body 4 rotates, the two sets of exhaust holes 5 are staggered at different angles. The larger the angle, the smaller the overlap, the smaller the opening of the exhaust hole 5, and the slower the air release speed; conversely, the larger the opening, the faster the air release speed. When rotated to the required angle, the second limiting seat 9 on the rotating rod of the ball valve body 4 will cooperate with the locking tongue 8 on the first limiting seat 6. The first limiting seat 6 is evenly distributed with three sets of springs 7 and locking tongues 8 along the circumference of the rotating rod of the ball valve body 4. The springs 7 push the locking tongue 8 into the limiting groove of the second limiting seat 9, locking the ball valve body 4 in three positions. At one of the same angles, the size of the exhaust port 5 is fixed, thus achieving stable control of the deflation speed. When the U-shaped pillow body 1 needs to be inflated, the air bladder 11 is squeezed, the internal space of the air bladder 11 becomes smaller, and the air pressure increases. At this time, the one-way exhaust valve 13 opens and the one-way intake valve 12 closes. Under the action of pressure, the gas in the air bladder 11 enters the inner cavity of the U-shaped pillow body 1 through the one-way exhaust valve 13 and along the inflation channel 10, completing one inflation action. After releasing the air bladder 11, the air bladder 11 returns to its original shape, the internal air pressure decreases, and the one-way intake valve 12 opens. Under the action of atmospheric pressure, the outside air enters the air bladder 11 through the one-way intake valve 12, preparing for the next inflation. This cycle is repeated to achieve continuous inflation of the U-shaped pillow body 1.
