Description

Technical Field

[0001] This invention relates to the field of air pump equipment technology, specifically to a small, automated integrated air pump device and method thereof. Background Technology

[0002] An air pump, also known as a tire inflator, uses a motor to create airflow and then uses air pressure to inflate the object. It's typically used as an inflation device, taken out when needed and stored away afterward. It's very convenient and quick for inflation operations.

[0003] Inflatable mattresses are convenient to use and easy to store when not in use, as they can be deflated and stored away easily. This has led to their popularity in recent years. However, inflatable mattresses require an air pump to inflate them. While modern air pumps are highly efficient and can be quickly inflated by simply aligning them with the inflation port, they cannot simultaneously deflate the mattress. Deflating requires manual adjustment and replacement of the inflation / deflation device, making the process inconvenient.

[0004] Furthermore, the inflation pressure of existing air pumps is completely unknown during inflation, and whether the air mattress is fully inflated depends entirely on the user's experience, making it impossible to achieve automated inflation. In addition, different users have different requirements for the firmness of the air mattress, and existing air pumps cannot automatically adjust the inflation pressure, which greatly affects the user experience.

[0005] Therefore, in order to solve the problems of inconvenient operation during the inflation and deflation process of air-filled beds, unknown inflation pressure, and unadjustable inflation pressure, it is now necessary to provide a small-scale automated integrated air pump device and method. Summary of the Invention

[0006] The present invention aims to provide a small, automated, integrated air pump device and method to solve the problems of inconvenience in the inflation and deflation process of air beds and the inability to adjust the inflation pressure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This invention primarily addresses the problems of inconvenient and cumbersome operation during the inflation and deflation of air-filled beds, as well as the inability to adjust the inflation pressure. Specifically, it provides a method for using a small, automated, integrated air pump device. By sensing the gas pressure value of the air-filled bed, it controls the opening and closing states of valve assembly A and valve assembly B to adjust the gas flow direction, achieving integrated switching between inflation and deflation. The method includes the following steps:

[0009] Step 1: Set the inflation parameters according to user needs;

[0010] Step 2: When inflating, start the air pump according to the initial inflation state, and make valve assembly A open and valve assembly B sealed.

[0011] Step 3: Determine the inflation pressure and inflation parameter values, and adjust the opening and closing states of valve assembly A and valve assembly B according to the determination results to switch between inflation and deflation.

[0012] The principles and advantages of this scheme are:

[0013] In the use of air mattresses, inflation is generally achieved using an air pump. Since the air pump can only inflate, deflation requires removing the pump, either to deflate directly or by replacing it with a deflator. This makes the inflation and deflation process cumbersome. Therefore, for convenience, deflation is typically done directly to reduce the amount of equipment carried. Because deflation can be performed without any additional equipment, and to reduce costs and improve the weight of the equipment, the air pump design does not include a deflator function.

[0014] Furthermore, during the use of air mattresses, people only care about whether they are fully inflated and whether they are properly inflated, without much concern about the amount of air. They believe that the comfort of an air mattress is related to the material of the mattress itself, not the inflation pressure. However, through numerous experiments and verifications, we have learned that the comfort of an air mattress is actually closely related to the inflation pressure. When over-inflated, the mattress will be firmer, while under-inflated, it will be softer. Different users will find different levels of comfort. However, most air mattress designs do not offer intuitive control and adjustment of inflation pressure, making it a blind spot that is difficult to control and adjust.

[0015] This solution uses a pressure sensor to automatically sense the inflation pressure, making the pressure value more intuitive and controllable. Based on the pressure value, it can automatically adjust and control the inflation and deflation of the air pump to achieve automatic inflation and deflation operation. This allows for controllable and adjustable inflation pressure, making the inflation pressure more closely match the user's actual needs and improving the comfort of the air mattress.

[0016] Furthermore, this solution controls and adjusts the opening and closing state of the valve assembly to achieve the switching of inflation and deflation states through a single air pump, eliminating the need to replace the air pump separately, simplifying the air pump structure, and improving the air pump's portability.

[0017] Furthermore, in step two, the initial state is set to an inflation pressure of 4000-8000 Pa. When the inflation pressure is sensed to reach the initial pressure value, valve assembly A is closed.

[0018] Beneficial effects: The initial state allows for faster inflation, saving the initial inflation process and quickly reaching an inflation pressure of 4000-8000Pa. Fine-tuning can then be done based on the inflation pressure, resulting in more precise control.

[0019] Furthermore, in step three, when it is determined that the inflation pressure is less than the inflation parameter value, valve assembly A remains open and valve assembly B remains sealed; when it is determined that the inflation pressure is greater than the inflation parameter value, valve assembly B is opened and valve assembly A is closed, so that valve assembly A is sealed.

[0020] Beneficial effects: The valve assembly automatically adjusts its opening and closing state based on the judgment result, thereby realizing automatic switching between inflation and deflation, improving automation control. At the same time, the switching process is simple and convenient, which helps to simplify the structure of the air pump and improve the lightweight requirements of the air pump.

[0021] Furthermore, step four involves closing the corresponding valve assembly and shutting down the air pump once the inflation pressure is detected to have reached the set inflation parameter value.

[0022] Beneficial effects: The valve assembly is precisely controlled according to the inflation pressure, which improves the efficiency of the inflation and deflation switching process, thereby accurately controlling the inflation and deflation pressure values, so that the inflation pressure reaches the set inflation value and improves the comfort of the air mattress.

[0023] Furthermore, in step one, the inflation parameter value is the inflation pressure value set by the user based on their own sleeping habits, the fit with the bed, their weight, and the firmness of the bed.

[0024] Beneficial effects: By setting inflation parameters according to the user's own habits, the air mattress can better conform to the human body, meet the user's needs for the softness and firmness of the air mattress, thereby improving comfort and enhancing the user experience.

[0025] A small, automated integrated air pump device, applied in the aforementioned small, automated integrated air pump device application method, includes a housing; a receiving chamber is provided in the middle of the housing, with a first through hole and a second through hole respectively at both ends of the receiving chamber; a valve assembly A is provided at the front end of the first through hole, and a valve assembly B is provided at the front end of the second through hole; a first air window and a second air window are also provided at the upper end of the housing, with the first air window located above the first through hole and the second air window located above the second through hole; an air pump is provided inside the receiving chamber, with a first air port and a second air port respectively at both ends of the air pump, the first air port communicating with the first through hole and the second air port communicating with the second through hole; a pressure sensing device is also provided inside the housing, and the pressure sensing device is connected to the air pump.

[0026] Furthermore, a first air vent slot and a second air vent slot are respectively provided on both sides of the receiving compartment; the first through hole passes through the first air vent slot and its end is located outside the housing, and the first air vent is located above the first air vent slot; the second through hole passes through the second air vent slot and its end is located outside the housing, and the second air vent is located above the second air vent slot.

[0027] Beneficial effects: By using the air window and through hole, the airflow direction in the air pump is changed. When inflating, the air is drawn into the air pump through the air window, and when deflating, the air is discharged through the air window. Thus, the inflation and deflation process can be switched easily without changing any structure or replacing the air pump.

[0028] Furthermore, the first through hole has a first retaining ring at its front end, which abuts against the valve assembly A. The first retaining ring has a hole on its inner side, which is in the open state when it is connected to the valve assembly A. The second through hole structure is symmetrically arranged with respect to the first through hole structure.

[0029] Beneficial effects: The first retaining ring can limit the movement of the through hole, controlling its distance and ensuring gas flow. It also maintains a seal when the corresponding through hole needs to be closed.

[0030] Furthermore, a drive motor is also provided inside the housing, located below the receiving chamber. The drive motor drives the receiving chamber to move, and is connected to the pressure sensing device.

[0031] Beneficial effects: By driving the container to move left and right within the housing using a drive motor, the opening and closing state of the valve assembly can be controlled and adjusted to achieve an automatic inflation / deflation process. Furthermore, the pressure sensor can further control the operation of the drive motor based on the inflation pressure, thereby controlling the start and stop status of the inflation pump and achieving automatic adjustment.

[0032] Furthermore, the overall length of the air pump does not exceed 100mm, the width does not exceed 54mm, and the height does not exceed 63mm. The air pump includes a pump casing, a motor is installed inside the pump casing, and an impeller is installed on the left side of the motor.

[0033] This solution designs a valve assembly to control the opening and closing states of different through holes, and uses an air window to switch the airflow direction. This allows inflation and deflation to be achieved with a single air pump, integrating inflation and deflation without the need for additional air pumps. This enables automatic switching, reduces the size of the air pump, improves lightweight design, and eliminates the need to replace the air pump separately, making inflation and deflation operations simpler and more convenient.

[0044] The following detailed description illustrates the specific implementation method:

[0045] The reference numerals in the accompanying drawings include: housing 1, air pump 2, receiving chamber 3, first through hole 4, second through hole 5, valve assembly A, valve assembly B, first air window 6, second air window 7, first air port 8, second air port 9, pressure sensor 10, air valve 11, reset device 12, pump housing 13, motor 14, impeller 15, drive motor 16, first air window slot 17, second air window slot 18, first retaining ring 19, second retaining ring 20, motor cavity 21, impeller cavity 22, indicator light 23, control switch 24, hole 25, gear rack 26.

[0046] Example 1

[0047] Application methods for small, automated, integrated air pump devices are shown in the attached document. Figure 1 As shown, by sensing the gas pressure value of the air-filled bed, the opening and closing states of valve assembly A and valve assembly B are controlled to adjust the gas flow direction and achieve integrated switching of inflation and deflation; specifically, the following steps are included:

[0048] S1. Set inflation parameters according to user needs. These inflation parameters are the pressure values ​​set by the user based on their sleeping habits, fit to the bed, weight, and the firmness of the bed. In this embodiment, the inflation parameters can be categorized: 2000-3000 Pa is considered softer, 3500-5000 Pa is moderate, and 5500-8000 Pa is firmer. Users can select and set these reference values ​​and further fine-tune them according to their needs to improve comfort and inflation efficiency.

[0049] S2, when inflation begins, press button A or control the drive motor via the APP to drive the gear rack 26 to open valve assembly A. At this time, the drive motor remains in place, and the inflation pump is started according to the initial inflation state, so that valve assembly A is in the open state and valve assembly B is in the sealed state.

[0050] Specifically, the initial inflation pressure is set to 4000-8000 Pa, as shown in the attached figure. Figure 2 As shown, when valve assembly A is open and valve assembly B is sealed, the air pump 2 starts, and the impeller 15 rotates, causing the gas inside the air pump 2 to circulate. The gas enters through the second air window 7, passes through the air pump 2, and then inflates the air bed through the first through hole 4. When the pressure sensor 10 senses that the inflation pressure has reached the initial pressure value, valve assembly A is closed, achieving the initial inflation state. This allows for rapid initial inflation of the air bed, improving early inflation efficiency and shortening inflation time.

[0051] S3, during the inflation process, determines the inflation pressure and inflation parameter values, and adjusts the opening and closing states of valve assembly A and valve assembly B according to the determination results to switch between inflation and deflation.

[0052] Specifically, the judgment mainly falls into the following two categories:

[0053] (1) When it is determined that the inflation pressure is less than the inflation parameter value, it means that the inflation pressure is not enough and inflation needs to continue. At this time, valve assembly A will continue to be in the open state and valve assembly B will be in the sealed state.

[0054] (2) When it is determined that the inflation pressure is greater than the inflation parameter value, valve assembly B is opened and valve assembly A is closed, so that valve assembly A is in a sealed state.

[0055] This indicates that the inflation pressure is too high and needs to be evacuated. At this time, there is no need to remove the air pump. Instead, press button B or open the valve assembly B by turning on the drive motor drive gear 26 through the APP. The drive motor will hold and simultaneously send a signal to the air pump to start evacuating. When the evacuated air pressure reaches the sensing value of the pressure sensor (-2000-8000Pa), the pressure sensor will issue a stop command, the drive motor will return to its original position, and the valve assembly B will return to its original sealing position under the action of the reset device 12, thus completing the rapid deflation process.

[0056] When valve assembly B is open, valve assembly A is in a sealed state, as shown in the attached diagram. Figure 3 As shown, the air pump 2 generates internal flowing gas under the rotation of the impeller 15. At this time, the gas in the air bed will enter the second through hole 5 and pass through the air pump 2, and be discharged through the first air window 6, realizing the automatic deflation process.

[0057] In this embodiment, the inflation pressure can be set more intuitively and accurately according to the user's actual needs to meet the user's requirements. At the same time, during the inflation process, the pressure sensor 10 automatically senses the air pressure value of the air bed and automatically adjusts the inflation and deflation process according to the air pressure value, making the air pressure value controllable and achieving the effect of precise control, thereby improving the comfort of the air bed and better meeting the user's needs.

[0058] Example 2

[0059] This embodiment provides a small, automated, integrated air pump device that integrates inflation and deflation. This eliminates the need for separate adjustments when inflation or deflation is required, improving operational convenience and reducing the pump's size for easier portability. Furthermore, it can automatically adjust the inflation pressure based on a set pressure, achieving automatic inflation and deflation and enhancing automation performance. See attached figure for details. Figure 4 As shown: The shell 1 has an overall rectangular parallelepiped structure, with a length of 198mm, a width of 90mm, and a height of 108mm. The shell 1 has an inwardly recessed receiving chamber 3 in the middle, allowing the air pump 2 to be installed horizontally inside the receiving chamber 3.

[0060] For details, see attached. Figure 5 and attached Figure 6 As shown, a first air vent 17 and a second air vent 18 are respectively provided at both ends of the housing 1, and the bottoms of the first air vent 17 and the second air vent 18 are connected to the lower end of the housing 1. A first through hole 4 and a second through hole 5 are respectively provided at both ends of the receiving compartment 3. The first through hole 4 passes through the first air vent 17 and leads to the outside of the left side of the housing 1, and the second through hole 5 passes through the second air vent 18 and leads to the outside of the right side of the housing 1.

[0061] A first air vent 6 is installed above the first air vent slot 17 to facilitate the flow of gas from or into the first air vent 6 and to the first through hole 4; a second air vent 7 is installed above the second air vent slot 18 to facilitate the flow of gas from or into the second air vent 7 and to the second through hole 5.

[0062] For details, see attached. Figure 6 As shown, a first retaining ring 19 is integrally formed on the outer side of the first through hole 4. The first retaining ring 19 is located outside the housing 1, allowing the first through hole 4 to move left and right outside the housing 1 via the first retaining ring 19. At the same time, the first retaining ring 19 ensures the sealing of the first through hole 4 when it comes into contact with the housing 1, thus ensuring the accuracy of the inflation / deflation switching process. Meanwhile, two holes 25 are formed on the wall of the first through hole 4, located inside the first retaining ring 19. This allows the holes 25 to communicate with the gas valve 11 when the first through hole 4 moves, thereby realizing gas exchange. When in a sealed state, the holes 25 do not affect the sealing performance.

[0063] A valve assembly A is also installed on the outside of the first through hole 4. The valve assembly A, in conjunction with the first through hole 4, can be configured to be open or sealed. (See attached diagram.) Figure 6 As shown, valve assembly A includes a pneumatic valve 11 mounted on the outside of housing 1 and a reset device 12. The reset device 12 is mounted on the first through hole 4 and sleeved on the outside of the first retaining ring 19. When the first through hole 4 moves to the left, it squeezes the reset device 12 and connects the first through hole 4 with the pneumatic valve 11. When the operation is completed, the reset device 12 uses its elasticity to drive the first through hole 4 to move to the right and return to its sealed position. In this embodiment, the reset device 12 uses a reset spring, which drives the motor 16 to switch between open and sealed states, and the reset spring also ensures continuous sealing.

[0064] Similarly, a valve assembly B is installed on the outside of the second through hole 5, which allows the second through hole 5 to be in an open or sealed state. In this embodiment, the valve assembly B has the same structure as the valve assembly A, both using a pneumatic valve and a reset device, which will not be described in detail here. At the same time, a second retaining ring 20 is also provided on the second through hole 5 to achieve a sealing effect. Two holes 25 are also formed in the wall of the second through hole 5 so that when the second through hole 5 moves, it can communicate with the pneumatic valve through the holes 25 to achieve gas exchange.

[0065] Specifically, in conjunction with the appendix Figure 7 and attached Figure 8As shown, a drive motor 16 is installed at the lower part of the housing 1, located below the receiving chamber 3. The drive motor 16 is connected to the receiving chamber 3 via a gear rack 26. The rotation of the drive motor 16 drives the gear rack to move, thereby moving and positioning the receiving chamber 3 left and right within the housing 1. This allows for adjustment of the opening and closing state of valve assembly A or valve assembly B through the through-hole. A pressure sensor 10 is also installed on one side of the drive motor 16. The pressure sensor 10 is electrically connected to both the drive motor 16 and the air pump 2. The pressure sensor 10 detects the inflation pressure of the air bed, controlling the operation of the drive motor 16 and the motor 14, thereby controlling the inflation and deflation process of the air pump. This achieves automatic inflation and deflation operation, simplifies the inflation and deflation switching process of the air pump, and improves inflation and deflation efficiency.

[0066] For details, see attached. Figure 9 and attached Figure 10 As shown, the air pump 2 has an overall rectangular parallelepiped structure, with a length of 100mm, a width of 54mm, and a height of 63mm. The air pump 2 includes a pump housing 13, which includes a motor cavity 21 and an impeller cavity 22. The motor cavity 21 is located on the right side of the impeller cavity 22 and communicates with it. A first air port 8 is provided at the right end of the motor cavity 21, communicating with a first through hole 4. A second air port 9 is provided on the left side of the impeller cavity 22, communicating with a second through hole 4, allowing the first through hole 4, the first air port 8, the second air port 9, and the second through hole 5 to communicate with each other.

[0067] Specifically, a motor 14 is installed in the motor cavity 21, and an impeller 15 is installed in the impeller cavity 22. The impeller 15 is installed at the drive end of the motor 14, and the motor 14 drives the impeller 15 to rotate, thereby generating airflow inside the air pump.

[0068] As attached Figure 9 As shown, indicator lights 23 and control switches 24 are also installed on the outside of the pump housing 13. Indicator lights 23 are used to display the inflation status of the air pump 2. In this embodiment, there are three indicator lights: IN (inflation), OUT (deflation), and a red light for fault. Control switches 24 include two switches: button A and button B. Button A is the inflation switch, and button B is the deflation switch. Specifically, button A is used to control valve assembly A to open, and button B is used to control valve assembly B to open.

[0069] In this embodiment, the deflation process can be quickly completed using the air pump without removing it by changing the opening and closing state of the valve assembly. Furthermore, after deflation, it can be stored directly with the air mattress, avoiding the inconvenience of separate storage. Generally, when deflating an air mattress, for ease of operation, a natural deflation process is used, where the inflation port is opened and the internal gas flows out directly under external pressure or naturally, rather than the more troublesome process of replacing the air pump. This would undoubtedly increase the complexity of the air mattress setup, making it cumbersome to use and requiring the user to carry two sets of equipment; therefore, adding a deflator pump is not considered.

[0070] This application integrates the air pump and the deflator into one unit. When air needs to be deflated, the air pump does not need to be removed. Instead, the deflation process is achieved by switching the opening and closing state of the valve assembly. The deflation is automatically controlled according to the pressure value, which greatly shortens the deflation time, improves the convenience of operation, and increases the deflation efficiency. After completion, the user does not need to remove the air pump. It can be stored directly with the air bed, making the operation simpler and faster, and easier to store. It can be used directly next time.

[0071] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
