Description

Technical Field

[0001] This utility model belongs to the technical field of door security equipment and relates to a door top device. Background Technology

[0002] When using a common door jack, one end is pressed against the door and the other end against the ground. The external force acting on the door is transmitted to the ground by the door jack. Some door jacks have a leg-like curved arm at the end that is pressed against the ground. The external force that pushes the door has a component force parallel to the ground and pushing the door jack along the curved arm. This component force needs to be offset by the static friction between the ground and the door jack. If the coefficient of friction of the side that is pressed against the ground is not high, the door jack will fail to push the door open.

[0003] Currently, some door jacks have suction cups on the side that touches the ground, creating a vacuum space within the suction cups. This effectively counteracts the force exerted by the large external force pushing the door, which is parallel to the ground and pushes the door jack horizontally. However, because the vacuum within the suction cups is difficult to maintain effectively and continuously, the overall door-jacking effect is not good when consumers use the door jacks. Utility Model Content

[0004] To address the technical problem of maintaining a consistently high vacuum level within the suction cup of a door-mounting device, this invention provides a door-mounting device comprising a door-mounting end, a support end in contact with the ground, a vacuum pump with an exhaust port and an extraction port, and a control circuit powered by an electrical supply. The support end includes a suction cup, an adsorption chamber located inside the suction cup, and an extraction channel connecting the adsorption chamber to the extraction port of the vacuum pump. The vacuum pump is electrically connected to the control circuit. The door-mounting device further includes a gas pressure detection end connected to the adsorption chamber. This gas detection end is electrically connected to the control circuit. When the gas pressure detected by the gas detection end is within a set pressure range, the control circuit shuts off the vacuum pump; when the gas pressure detected by the gas detection end exceeds the set pressure range, the control circuit turns on the vacuum pump. Using this door-mounting device ensures that the adsorption chamber always maintains a certain vacuum level during use, which can counteract the pushing force from the door. Furthermore, due to the automatic control of the control circuit, the vacuum pump does not need to operate continuously, but only when the gas pressure within the adsorption chamber exceeds the set pressure range, greatly saving power.

[0005] The present invention also adopts the following technical solution:

[0006] The top door device also includes a gas channel connecting the adsorption chamber to the outside air and a valve installed on the gas channel to close or open the gas channel.

[0007] The valve is a solenoid valve that is electrically connected to the control circuit.

[0008] The top door end is equipped with a vibration sensor that senses vibrations from the door. The vibration sensor is electrically connected to the control circuit. When the vibration from the door is sensed by the vibration sensor, the control circuit turns on the vacuum pump regardless of whether the air pressure detected by the air pressure detection end is within the set air pressure range.

[0009] The top door end is equipped with a pressure sensor that senses the pushing force from the door. The pressure sensor is electrically connected to the control circuit. When the pushing force from the door is sensed by the pressure sensor, the control circuit turns on the vacuum pump regardless of whether the air pressure detected by the air pressure detection end is within the set air pressure range.

[0010] The top door end is equipped with a vibration sensor and a buzzer to sense vibrations from the door. Both the vibration sensor and the buzzer are electrically connected to the control circuit. When the vibration from the door is sensed by the vibration sensor, the control circuit turns on the buzzer.

[0011] The top door end is equipped with a pressure sensor and a buzzer to sense the pushing force from the door. Both the pressure sensor and the buzzer are electrically connected to the control circuit. When the pushing force from the door is sensed by the pressure sensor, the control circuit turns on the buzzer. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of each component of the top door device described in Example 1. Detailed Implementation

[0013] This section provides a detailed description of the utility model's content.

[0014] This utility model relates to a door jack, specifically including a door jack end, a support end in contact with the ground, a vacuum pump with an exhaust port and an extraction port, and a control circuit powered by an electrical supply. The support end includes a suction cup, an adsorption chamber located inside the suction cup, and an extraction channel connecting the adsorption chamber to the extraction port of the vacuum pump. The vacuum pump is electrically connected to the control circuit. Under the control of the control circuit, the vacuum pump evacuates the adsorption chamber, allowing the suction cup to adhere tightly to the ground and counteract the effect of external forces on the door jack. Furthermore, this utility model adds a pressure detection end connected to the adsorption chamber, which is electrically connected to the control circuit. When the pressure detected by the pressure detection end exceeds a set pressure range, the control circuit automatically turns on the vacuum pump to evacuate the adsorption chamber. When the pressure detected by the pressure detection end is within the set pressure range, the control circuit automatically turns off the vacuum pump. This ensures that the pressure in the adsorption chamber is always maintained at a certain vacuum level while minimizing the vacuum pump's operating time and saving electricity. All of the above operations are automatically controlled by the control circuit, saving time and effort.

[0015] When the door jack is not in use, a sheet can be inserted between the suction cup and the ground to disrupt the vacuum environment within the suction chamber, causing the suction cup to detach from the ground. However, this operation is cumbersome, and inserting the sheet becomes difficult when the vacuum level within the suction chamber is high, thus success cannot be guaranteed. This invention adds a gas channel connecting the suction chamber to the outside air, along with a valve on the gas channel to open or close it. When the door jack is in use, the valve closes the gas channel, maintaining the vacuum environment within the suction chamber. When the door jack is not in use, the valve opens the gas channel, allowing outside air to enter the suction chamber, equalizing the air pressure within the suction chamber with the outside air pressure, allowing the consumer to retract the door jack. This solution is clearly more time- and labor-saving. The valve can be opened or closed manually. Furthermore, the valve is a solenoid valve electrically connected to a control circuit, allowing for automatic control of its opening and closing.

[0016] The above only ensures that the door pusher with suction cup can withstand a certain amount of external force during use. However, this utility model also focuses on whether the door pusher can still effectively hold the door in place under stronger external force. In fact, the set air pressure range can usually only withstand ordinary external force. For consumers with high safety requirements, the door pusher may not meet their usage requirements. Therefore, this utility model further adds a vibration sensor to the top end of some door-mounting devices to sense vibrations from the door. The vibration sensor is electrically connected to the control circuit. When the vibration from the door is sensed by the vibration sensor, the control circuit turns on the vacuum pump regardless of whether the air pressure detected by the air pressure detection end is within the set air pressure range. Specifically, when the air pressure detected by the air pressure detection end is within the set air pressure range, the vibration sensor senses vibration, which usually indicates that the external force acting on the door is large. The vacuum degree of the adsorption chamber may not be sufficient to firmly adsorb the suction cup onto the ground, making it difficult to counteract the external force. At this time, turning on the vacuum pump can further reduce the vacuum degree of the adsorption chamber, increase the firmness of the suction cup adsorbed onto the ground, and resist the large external force. Similarly, when the air pressure detected by the air pressure detection end is not within the set air pressure range, the vacuum pump is also turned on to increase the firmness of the suction cup adsorbed onto the ground. Similar to vibration sensors, pressure sensors are also used in some door closers. These sensors detect the force exerted by the door. They are electrically connected to the control circuit. When the pressure sensor detects the force from the door, the control circuit activates the vacuum pump, regardless of whether the pressure detected by the pressure sensor is within the set pressure range. Specifically, when the pressure detected by the pressure sensor is within the set pressure range, the pressure sensor detects pressure, usually indicating a large external force acting on the door. This may mean the vacuum level in the suction chamber is insufficient to firmly attach the suction cup to the ground, making it difficult to counteract the external force. Activating the vacuum pump at this time further reduces the vacuum level in the suction chamber, increasing the suction cup's adhesion to the ground and resisting the larger external force. Similarly, when the pressure detected by the pressure sensor is outside the set pressure range, the vacuum pump is activated to increase the suction cup's adhesion to the ground.

[0017] Furthermore, some door jacks are equipped with a vibration sensor and a buzzer at the top of the door to detect vibrations from the door. Both the vibration sensor and the buzzer are electrically connected to the control circuit. When the vibration sensor detects vibrations from the door, the control circuit activates the buzzer. Some door jacks are also equipped with a pressure sensor and a buzzer at the top of the door to detect the pushing force from the door. Both the pressure sensor and the buzzer are electrically connected to the control circuit. When the pressure sensor detects the pushing force from the door, the control circuit activates the buzzer, thereby attracting the user's attention and ensuring the user's safety.

[0018] Example 1

[0019] See Figure 1 A door jack includes a door jack end, a support end in contact with the ground, a vacuum pump 8, a control circuit 9, a solenoid valve 6, a pressure detection end 4, a vibration sensor 10, and a buzzer 11. The vacuum pump 8, solenoid valve 6, pressure detection end 4, vibration sensor 10, and buzzer are all electrically connected to the control circuit. The vibration sensor 10 is located at the door jack end. The support end includes a suction cup 1 with an adsorption chamber 2 inside. The vacuum pump 8 has an air outlet 8 and is connected to the adsorption chamber 2 through an air extraction port 3. The pressure detection end 4 is connected to the adsorption chamber 2 to detect the air pressure inside the adsorption chamber 2. The solenoid valve 6 is connected to the adsorption chamber 2 through a gas channel 5.

[0020] When the air pressure detected by the air pressure detection end 4 in the adsorption chamber 2 is within the set air pressure range, the control circuit 9 shuts off the vacuum pump 8. When the air pressure detected by the air pressure detection end 4 in the adsorption chamber 2 exceeds the set air pressure range, the vacuum pump 8 is turned on to maintain a certain vacuum in the adsorption chamber 2, so that the suction cup 1 has a considerable adsorption force on the ground, which can counteract the pushing force of the door on the top door end. When the top door is not in use, the control circuit 9 shuts off the vacuum pump 8 and opens the solenoid valve 6 to allow outside air to enter the adsorption chamber 2 through the gas channel 5, and the user can remove the top door.

[0021] In addition, when the door pushing force on the top of the door is too great and the resulting vibration is sensed by the vibration sensor 10, the control circuit 9 will turn on the vacuum pump 8 regardless of whether the air pressure in the suction chamber 2 is within the set air pressure range. This ensures that the suction cup 1 can be more firmly attached to the ground to counteract the door pushing force. The control circuit 9 can also turn on the honey dispenser 11 at the same time to remind the user to pay attention and ensure the user's personal safety.

[0022] Example 2

[0023] Example 2 is basically the same as Example 1, except that a pressure sensor is used instead of a vibration sensor.
