Description

Technical Field

[0001] The present invention relates to the technical field of mattress air pumps, in particular to an ultra-quiet, high-volume air pump for an intelligent mattress. Background Art

[0002] With the development of industrialization and the improvement of people's consumption capacity in my country, the mattress industry has developed rapidly. In the existing mattress industry, traditional mattress structures are usually composed of elastic sponge / rubber or springs. In actual use, the hardness of the springs or sponges and rubber is fixed, and they cannot adapt to the human body in a targeted manner. In addition, cheap mattresses will collapse due to the loss of elasticity of local springs during long-term use, which will lead to abnormal use. For this reason, smart mattresses with elastic adaptive structures have been developed.

[0003] The smart mattress in the prior art is usually composed of a mattress body, an air pump installed inside the mattress body, and an air bag connected to the air pump. At the same time, a control panel for controlling the air pump is installed inside the mattress body. The start and stop of the air pump is controlled by the control panel to achieve the expansion and contraction of the air bag, thereby achieving the elastic adaptive adjustment of the smart mattress. Since the air pump is directly installed inside the air bag, the air pump and the motor used to drive the air pump are affected by the height of the mattress body and have smaller specifications, resulting in a smaller air pump suction volume of the air pump, and the noise when the air pump is working is easily transmitted to the ears of the user, affecting the comfort during use.

[0004] To this end, we propose an ultra-quiet, high-volume air pump for a smart mattress to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

A transversely arranged transmission rod is connected to the drive shaft of the servo motor, and a gear 1 that meshes with the teeth on the gear disc is fixedly mounted at the end of the transmission rod away from the servo motor.

[0008] Furthermore, a gear 2 is fixedly mounted on the end of the transmission rod close to one side of the servo motor, and a gear 3 meshing with the gear 2 is fixedly mounted on the driving shaft of the servo motor.

[0009] Furthermore, a cavity provided as a hollow structure is opened inside the end wall of the pump casing and the cylindrical outer casing, and the interior of the cavity is filled with sound insulation cotton material, and the interior of the sound insulation cotton material is provided with a porous honeycomb structure.

[0010] Furthermore, a filling frame sleeved on the outside of the servo motor is fixedly mounted on the inner end wall of the cylindrical shell, and the filling frame is formed by splicing and fixing a plurality of longitudinally arranged regular hexagonal through pipes.

[0011] Furthermore, the air inlet opened at the bottom of the pump housing is fixedly connected to an air inlet pipe, and the shape of the air inlet pipe is set to be a spiral structure.

[0012] Furthermore, the end of the air inlet pipe away from the pump housing is fixedly connected to a plurality of air inlet branch pipes.

[0013] Furthermore, the ends of the plurality of air inlet branch pipes away from the air inlet pipe are all configured to have an upward opening structure, an exhaust pipe is fixedly connected to the outer end wall of the cylindrical shell, and the end of the exhaust pipe away from the cylindrical shell is configured to have a downward opening structure.

[0014] Furthermore, a plurality of the hoses are provided, and the plurality of hoses are evenly distributed and connected to the outer end wall of the cylindrical shell, and each of the hoses is fixedly connected to an elastic airbag at one end away from the cylindrical shell.

[0015] Furthermore, the connection points between the plurality of hoses and the cylindrical shell are all fixedly installed with an electrically controlled magnetic valve, and the connection point between the exhaust pipe and the cylindrical shell is also fixedly installed with an electrically controlled magnetic valve.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By vertically inserting the pump shaft for rotating the pump impeller into the interior of the pump housing and horizontally arranging the servo motor, the diameter of the pump housing and the length of the servo motor can be appropriately increased, which is beneficial to increasing the airflow compression space during the rotation of the pump impeller inside the pump housing, avoiding its working size being affected by the thickness of the smart mattress, thereby effectively improving the efficient air extraction capacity of the device. At the same time, by arranging the cylindrical shell on the outside of the servo motor, the servo motor can be isolated and protected, reducing the probability of the noise generated by the internal operation of the servo motor being transmitted to the outside, and the airflow is filled into the interior of the cylindrical shell with the help of the adapter tube, which is beneficial to actively reduce the heat outside the servo motor with the help of the airflow generated during operation, thereby improving the stability of the silent heat dissipation work of the device during operation to a certain extent;

[0018] 2. By installing the mutually meshing toothed disc and gear 1 on the pump shaft and the transmission rod respectively, the power transmitted on the servo motor drive shaft can be stably transmitted to the pump shaft, effectively ensuring the stability of power transmission on the device. By fixing gear 3 on the drive shaft of the servo motor and fixing gear 2, which is meshed with gear 3, on the end of the transmission rod, the rotational power on the servo motor drive shaft can be staggered and transmitted to the transmission rod, which is conducive to further coordinating the installation position between the servo motor and the pump housing, thereby effectively improving the structural rationality of the device and preventing the overall height of the device from affecting the thickness of the smart mattress.

[0019] 3. By setting the interior of the end wall of the pump casing and the cylindrical shell into a hollow cavity structure and filling the cavity with sound insulation cotton material, the noise isolation effect of the pump casing and the cylindrical shell can be effectively improved. At the same time, by setting the interior of the sound insulation cotton material into a porous honeycomb structure, the honeycomb structure absorbs sound energy and converts sound energy vibration into heat energy, which can further enhance the isolation effect of the device on the noise generated during operation, and is conducive to improving the ultra-quiet effect of the device during operation;

[0020] 4. By fixing the filling frame on the outside of the servo motor and fixing the filling frame inside the cylindrical shell, a stable structural support can be formed between the servo motor and the cylindrical shell, thereby effectively ensuring the structural stability of the servo motor during operation and reducing the probability of its vibration and noise generation. At the same time, by splicing and fixing a plurality of regular hexagonal through-tubes to form a filling frame, the contact area between the servo motor and the airflow when dissipating heat outward can be effectively increased, which is conducive to improving its heat dissipation effect. In addition, by splicing the regular hexagonal through-tubes, the cross-section of the filling frame forms a honeycomb structure, which can further reduce the noise of the passing airflow and further improve the quiet stability of the device during operation.

[0021] 5. By fixing the spiral air inlet pipe on the air inlet at the bottom of the pump housing, the number of right-angle turns of the airflow entering the pump housing can be reduced with the help of the air inlet pipe, thereby effectively improving the efficiency of the airflow entering the pump housing, thereby improving the air intake and extraction volume of the device to a certain extent. By fixing and connecting multiple air inlet branch pipes to the air inlet pipe, the multiple air inlet branch pipes can be dispersed and arranged at different positions inside the smart mattress, which is conducive to improving the air intake balance of the device.

[0022] 6. By fixing the exhaust pipe to the outer end wall of the cylindrical shell and arranging the opening of the exhaust pipe to face downward, and coordinating the openings of the multiple air inlet pipes to face upward, moisture can be extracted from above the smart mattress equipped with the device through the air inlet pipes and the extracted moisture can be discharged downward, which is conducive to ensuring the dryness of the interior of the smart mattress equipped with the device.

[0023] 7. By evenly distributing and connecting multiple hoses on the outer end wall of the cylindrical shell, and connecting an elastic airbag to each hose, multiple elastic airbags can be dispersedly installed inside the smart mattress, which is conducive to decentralized inflation operation, and thus helps to improve the inflation efficiency of the device. By installing an electrically controlled solenoid valve at the connection between each hose and the cylindrical shell, and fixing the same electrically controlled solenoid valve at the connection between the exhaust pipe and the cylindrical shell, by controlling the opening and closing of multiple electrically controlled solenoid valves, the expansion of the corresponding elastic airbags and the conduction of the exhaust pipe can be flexibly adjusted according to usage requirements, effectively improving the flexibility of the device during use.

[0038] See also Figures 1-9 , an embodiment of the present invention provides: an ultra-quiet, large-volume air pump for an intelligent mattress, comprising a pump casing 1, a pump shaft 101 arranged to pass through the upper and lower parts of the pump casing 1 is rotatably connected at the top middle position of the pump casing 1, and a pump impeller 102 arranged inside the pump casing 1 is fixedly installed at the lower end of the pump shaft 101, an air inlet is opened at the bottom middle position of the pump casing 1, a transfer pipe 103 is fixedly connected to the side end wall of the pump casing 1, a transversely arranged servo motor 104 is fixedly installed on the outer end wall of the pump casing 1, and the drive shaft of the servo motor 104 is transmission-connected to the pump shaft 101, a cylindrical casing 2 fixedly connected to the outer end wall of the pump casing 1 is sleeved on the outer side of the pump shaft 101 and the servo motor 104, the other end of the transfer pipe 103 is fixedly connected to one side end wall of the cylindrical casing 2, a hose 4 is fixedly connected to the other side end wall of the cylindrical casing 2, and an elastic airbag 401 is fixedly connected to the end of the hose 4 away from the cylindrical casing 2, and an electrically controlled magnetic valve 403 is fixedly installed at the connection between the hose 4 and the cylindrical casing 2.

[0039] During the activation of the device, the relevant staff will install the device horizontally at a suitable position inside the applicable smart mattress, and install the elastic airbag 401 to a suitable position. The staff will connect the device to an external power supply through a wire so that the external power supply provides power support for the device. Then, the staff will control the device to be powered on and started. After the servo motor 104 is powered on and started, it will drive the pump shaft 101 connected to it to rotate, and then drive the pump wheel 102 installed on the outside of the pump shaft 101 to rotate inside the pump housing 1. With the help of the pump wheel 102 when it rotates, the external gas is drawn in through the air inlet opened at the bottom of the pump housing 1, and the gas is pumped in through the adapter opened on the outer end wall of the pump housing 1. The tube 103 is discharged into the interior of the cylindrical shell 2, and then input into the elastic airbag 401 through the hose 4, and the inflation and expansion of the elastic airbag 401 is controlled. The opening and closing of the electric-controlled magnetic valve 403 installed at the connection between the hose 4 and the cylindrical shell 2 is used to realize the conduction and cutoff control of the hose 4, and then the expansion state of the elastic airbag 401 is controlled in real time. During the inflation and expansion process, the electric-controlled magnetic valve 403 is in the open state. During the airflow process, due to the guidance of the transfer tube 103 and the cylindrical shell 2, the airflow will flow inside the cylindrical shell 2, and then flow at high speed on the outside of the servo motor 104, which is conducive to active heat dissipation operation on the outside of the servo motor 104.

[0040] By vertically inserting the pump shaft 101 for rotating the pump impeller 102 into the interior of the pump casing 1 and horizontally arranging the servo motor 104, the diameter of the pump casing 1 and the length of the servo motor 104 can be appropriately increased, which is beneficial to increasing the airflow compression space during the rotation of the pump impeller 102 inside the pump casing 1, avoiding its working size from being affected by the thickness of the smart mattress, thereby effectively improving the efficient air extraction capacity of the device.

[0041] See also Figure 1 、 Figure 7 and Figure 8The gear 105 and the gear 107 that mesh with each other are respectively installed on the pump shaft 101 and the transmission rod 106, so that the power transmitted on the driving shaft of the servo motor 104 can be stably transmitted to the pump shaft 101, thereby effectively ensuring the stability of power transmission on the device.

[0042] See also Figure 1 、 Figure 5 and Figure 8 , a gear 2 108 is fixedly installed at the end of the transmission rod 106 close to one side of the servo motor 104, and a gear 3 109 meshing with the gear 2 108 is fixedly installed on the driving shaft of the servo motor 104. When the device is working, the gear 3 109 is fixedly installed on the driving shaft of the servo motor 104, and the gear 2 108 meshing with the gear 3 109 is fixedly installed at the end of the transmission rod 106, so that the rotational power on the driving shaft of the servo motor 104 can be staggered and transmitted to the transmission rod 106, which is conducive to further coordinating the installation position between the servo motor 104 and the pump housing 1, thereby effectively improving the structural rationality of the device and avoiding the overall height of the device affecting the thickness of the smart mattress.

[0043] See also Figure 5 and Figure 7 The end walls of the pump casing 1 and the cylindrical casing 2 are provided with a cavity set as a hollow structure, and the interior of the cavity is filled with sound insulation cotton material, and the interior of the sound insulation cotton material is set as a porous honeycomb structure. When the device is working, by setting the interior of the end walls of the pump casing 1 and the cylindrical casing 2 as a hollow cavity structure and filling the interior of the cavity with sound insulation cotton material, the noise isolation effect of the pump casing 1 and the cylindrical casing 2 can be effectively improved. At the same time, by setting the interior of the sound insulation cotton material to a porous honeycomb structure, the honeycomb structure absorbs sound energy and converts sound energy vibration into heat energy, which can further enhance the isolation effect of the device on the noise generated when it is working, which is beneficial to improving the ultra-quiet effect of the device when it is working.

At the same time, by splicing and fixing a plurality of regular hexagonal through tubes to form the filling frame 201, the contact area between the servo motor 104 and the airflow when dissipating heat outward can be effectively enhanced, which is beneficial to improving its heat dissipation effect.

When the device is working, the air inlet pipe 3 with a spiral structure is fixedly installed on the air inlet at the bottom of the pump casing 1. With the guidance of the air inlet pipe 3, the number of right-angle turns of the airflow entering the interior of the pump casing 1 can be reduced, thereby effectively improving the efficiency of the airflow entering the interior of the pump casing 1, thereby improving the air intake and exhaust volume of the device to a certain extent.

[0047] See also Figure 1-Figure 3 The end of the air inlet pipe 3 away from the pump housing 1 is fixedly connected to a plurality of air inlet branch pipes 301. When the device is working, by fixing the plurality of air inlet branch pipes 301 to the air inlet pipe 3, the plurality of air inlet branch pipes 301 can be dispersedly arranged at different positions inside the smart mattress, which is beneficial to improving the air intake balance of the device.

[0048] See also Figure 1-Figure 3 The ends of the multiple air inlet branch pipes 301 away from the air inlet pipe 3 are all configured to have an upward opening structure, and the outer end wall of the cylindrical shell 2 is fixedly connected to an exhaust pipe 402, and the end of the exhaust pipe 402 away from the cylindrical shell 2 is configured to have a downward opening structure. When the device is working, by fixing the exhaust pipe 402 to the outer end wall of the cylindrical shell 2 and configuring the opening of the exhaust pipe 402 to face downward, and configuring the openings of the multiple air inlet branch pipes 301 to face upward, the air inlet branch pipes 301 can be used to extract moisture from the top of the smart mattress equipped with the device, and the extracted moisture can be discharged downward, which is beneficial to ensuring the dryness of the interior of the smart mattress equipped with the device.

[0049] See also Figure 1 and Figure 2 There are a plurality of hoses 4, which are evenly distributed and connected to the outer end wall of the cylindrical shell 2. Each hose 4 is fixedly connected to an elastic airbag 401 on one end away from the cylindrical shell 2. When the device is working, by evenly distributing the plurality of hoses 4 on the outer end wall of the cylindrical shell 2 and connecting each hose 4 with an elastic airbag 401, the plurality of elastic airbags 401 can be dispersedly installed inside the smart mattress, which is conducive to decentralized inflation operation and thus helps to improve the inflation efficiency of the device.
