Description

Technical Field

[0001] The utility model relates to the technical field of built-in pumps, in particular to a built-in pump. Background Art

[0002] An airbed is a portable, inflatable bed that is usually used for camping, traveling, or temporary accommodation. A built-in pump is an air pump designed into the airbed for quick inflation and deflation. Traditional airbeds may require an external air pump or manual inflation, while a built-in pump makes the inflation process more convenient and efficient. The built-in pump is usually powered by an electric or battery, and the user only needs to press a button or switch to automatically complete the inflation or deflation operation. However, there are some problems with the built-in pump for airbeds when using it:

[0003] 1. When switching between inflation and degassing, the entire air pump needs to be taken out and the air port of the air pump needs to be replaced, which is cumbersome to operate;

[0004] 2. The inflation and exhaust pressure may be affected by other competing products, resulting in unstable performance;

[0005] 3. Using a right-angle baffle to seal the air port may reduce the air pressure and flow rate, and increase the noise. Therefore, the utility model proposes a built-in pump to solve the problems mentioned in the above background technology. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a built-in pump.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A built-in pump comprises a sealed cabin body, a wedge-shaped fairing is arranged on one side of the sealed cabin body, a silicone ring fixing baffle is arranged on the outside of the wedge-shaped fairing, a silicone ring is arranged between the silicone ring fixing baffle and the wedge-shaped fairing, and a spring is arranged inside the wedge-shaped fairing;

[0009] A converter knob is arranged on the upper side of the sealed cabin body, a connecting screw is arranged at the center of the converter knob, a converter upper cover corresponding to the converter knob is arranged inside the sealed cabin body, and a converter lower cover is arranged on the lower side of the converter upper cover, a stopper is arranged between the converter knob and the lower converter upper cover, and a second spring is arranged inside the stopper.

[0010] Preferably, a stopper is provided between the converter knob and the lower converter cover, and a second spring is provided inside the stopper.

[0011] Preferably, a sealed cabin cover is provided on the upper side of the sealed cabin body, and a corresponding normally closed switch and a rocker switch are provided on the inner surface of the sealed cabin body.

[0012] Preferably, a hatch cover boss corresponding to the normally closed switch is provided on the inner side of the sealed cabin hatch cover.

[0013] Preferably, a charging port is provided in the sealed cabin body, and a corresponding cabin cover silicone ring is provided on the inner side of the sealed cabin cover.

[0014] Preferably, the sealed cabin body further includes a battery cabin body, a corresponding conductive copper sheet is arranged on the upper side of the battery cabin body, and a corresponding battery cabin cover is arranged on the upper side of the battery cabin body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The movement of this utility model uses a unique ventilation structure (converter) to achieve inflation and exhaust at the same air port, which can avoid the trouble of taking out the entire air pump and changing the air pump air port to connect the air port of the airbed when switching between inflation and exhaust, and can also ensure that the inflation and exhaust pressure of this product is not affected by similar competing products;

[0017] 2. The utility model adopts a wedge-shaped fairing design at the air port connected to the air bed, which can ensure the air pressure and gas flow at this place. Unlike similar competing products, it will not directly use a right-angle baffle to seal the air port, thereby causing a decrease in air pressure and flow and an increase in noise;

[0018] 3. When the rocker switch is pressed to turn on the power, the air pump is in the working state of inflating or exhausting. At this time, you only need to close the hatch cover, and the boss on the hatch cover will press down the normally closed switch at the corresponding position on the circuit board, thereby closing the entire circuit and suspending the operation of the movement. You only need to open the hatch cover again and release the normally closed switch without operating the rocker switch to continue the previous unfinished working state;

[0019] If you need to completely stop the movement, you only need to press the rocker switch to shut down the entire circuit. This operating logic can ensure that as long as the hatch of the sealed cabin is opened and the outside gas is connected, the entire movement will work automatically to replenish or exhaust air, thus avoiding the deflation caused by delayed manual reaction when similar competing products open the hatch for manual operation.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-6 A built-in pump comprises a sealed cabin body 1, a wedge-shaped fairing 3 is arranged on one side of the sealed cabin body 1, a silicone ring fixing baffle 6 is arranged on the outside of the wedge-shaped fairing 3, a silicone ring 5 is arranged between the silicone ring fixing baffle 6 and the wedge-shaped fairing 3, and a spring 4 is arranged inside the wedge-shaped fairing 3;

[0029] Furthermore, a converter knob 12 is provided on the upper side of the sealed cabin body 1, a connecting screw 17 is provided at the center of the converter knob 12, a converter upper cover 13 corresponding to the converter knob 12 is provided inside the sealed cabin body 1, and a converter lower cover 14 is provided on the lower side of the converter upper cover 13, a stopper 16 is provided between the converter knob 12 and the lower converter upper cover 13, and a spring 2 15 is provided inside the stopper 16;

[0030] Furthermore, the product consists of two parts, namely a sealed cabin and a movement. The movement and the sealed cabin can be separated. The sealed cabin is fixed on the inflatable bed product by welding. When working, the movement is placed inside the sealed cabin.

[0031] Furthermore, the movement of this product has two working states, one is inflation, the other is exhaust. To switch between the two working states, you only need to rotate the converter knob to switch the connection port of the air duct. When in the inflation working state, the converter connects the fan outlet to the air bed, and the fan inlet to the outside world; when in the exhaust working state, the converter connects the fan outlet to the outside world, and the fan inlet to the air bed.

[0032] Furthermore, a damping spring and a block are installed inside the knob. When the knob drives the converter to rotate to a specific position, the converter is limited and cannot continue to move in the original direction. The block retracts and compresses the damping spring, which can separate the connection between the knob and the converter to avoid excessive rotation and damage to the internal structure. The movement of this product has a replaceable battery module, which can be quickly plugged in and out to achieve installation and uninstallation. The movement of this product has a three-stage camping light. Long press the switch to start the LED light source, press it again to increase the brightness, press it again to make the LED flash, and press it again to turn it off.

[0033] Furthermore, the sealed cabin of this product has two sealing functions. It is installed and fixed on the inflatable bed, and it has only one air port connected to the inside of the inflatable bed. The inflation and exhaust of the inflatable bed are realized through this single air port. A wedge-shaped fairing 3 is installed at the air port, and a spring is installed in the fairing. A silicone ring is fixed behind the fairing. When the movement of this product is taken out, the spring rebounds and pushes the fairing to move inside the sealed cabin, pulling the silicone ring so that the silicone ring is in close contact with the wall of the sealed cabin, thereby closing the air port and realizing the first seal of the sealed cabin. A silicone ring is installed on the inside of the hatch cover of the sealed cabin of this product. When the hatch cover is closed, the silicone ring is tightly compressed to close the hatch of the sealed cabin and realize the second seal. When the movement of this product is inserted, the spring is compressed, the fairing and the silicone ring retreat, and the air port is opened.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
