Description

Technical Field

[0001] The present application relates to the technical field of air pumps, and in particular to a self-heating air pump. Background Art

[0002] As a portable inflation tool, the micro air pump has developed from a single inflation function to an integrated inflation and discharge function.

[0003] In the existing technology, the inflation and deflation functions generally rely on a dual-motor independent drive architecture, that is, the inflation motor and the deflation motor are configured separately. Although this solution can achieve functional separation, it leads to a significant increase in material and assembly costs, and the dual motors occupy too much internal space, restricting the miniaturization design of the product; at the same time, the existing heat dissipation solution is not efficient enough, and the passive heat dissipation structure has a limited heat dissipation area under the miniaturized package, which is difficult to cope with the high temperature accumulation caused by the continuous operation of the dual motors.

[0004] Therefore, it is particularly important to design an air pump that has a single motor driven inflation and deflation function and optimizes heat dissipation and energy consumption performance. Summary of the invention

[0005] The purpose of this application is to provide a self-heating air pump to solve the above problems.

[0006] To achieve the above purpose, the technical solution of this application is: A self-heating air pump comprises a main body, wherein the main body comprises an inflation end, an installation area and a deflation end, and the deflation end is provided with a deflation interface; a double-axis head motor is provided inside the main body, and the double-axis head motor is transmission-connected to a piston rod at one end thereof facing the inflation end, and fan blades are connected to one end of the double-axis head motor facing the deflation end, and the fan blades are located in a connecting cavity, and the connecting cavity is connected to the deflation interface.

[0008] Preferably, a connecting hole is provided on one end of the mounting frame facing the dual-axis head motor, and the connecting hole connects the connecting cavity and the mounting area; a first flow guide gap is provided at the inflation end, and the first flow guide gap connects the outside of the main body and the mounting area; the connecting cavity, the mounting area, and the first flow guide gap together form a heat dissipation channel.

[0009] Preferably, there are a plurality of communicating holes, some of which are located on an area of ​​the mounting frame outside an area directly facing the dual-axis head motor, and are arranged circumferentially.

[0010] Preferably, an inflation port is provided at the inflation end. An interface limiting ring is sleeved on the inflation port. An inflation interface is provided on the interface limiting ring.

[0011] Preferably, the mounting bracket includes a mounting plate. The communication hole is opened on the mounting plate. A second diversion gap is provided between the mounting plate and the double-shaft head motor.

[0012] Preferably, a lining bracket is provided in the installation area. The mounting bracket is connected to one end of the lining bracket facing the deflation end. An end face gear is rotatably provided inside the lining bracket. An eccentric column is provided on the end face gear. The piston rod is hinged to the eccentric column. A rotating gear is provided at one end of the double-shaft head motor facing the inflation end. The rotating gear meshes with the end face gear.

A second internal thread hole is provided at one end of the limiting shaft inserted into the limiting hole. The second internal thread hole is opposite to the fixing hole.

[0016] The self-cooling air pump disclosed in the present application can dissipate heat from the entire air pump while inflating by setting a double-shaft head motor and a fan blade, and does not additionally increase a heat dissipation power mechanism, which not only reduces the cost but also saves the occupied space of the main body. In addition, by controlling the rotation direction of the double-shaft head motor, the present application can also quickly deflate the inflation device and dissipate heat from the entire interior of the main body during the deflation process. The inflation, deflation, and heat dissipation of the entire device adopt the same power structure, which greatly reduces the production cost of introducing an additional power mechanism and also reduces the occupied space inside the entire main body, thereby making the overall volume of the air pump smaller and easier to carry.

[0019] Now, the present application will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0020] As Figure 1-8 shown, a self-cooling air pump includes a body 1. The body 1 includes an inflation end 2, a mounting area, and a deflation end 3. The deflation end 3 is provided with a deflation interface 30. A double-shaft head motor 4 is provided inside the body 1. One end of the double-shaft head motor 4 facing the inflation end 2 is drivingly connected to a piston rod 9, and one end of the double-shaft head motor 4 facing the deflation end 3 is connected to a fan blade 56. The fan blade 56 is located in the communication cavity 55, and the communication cavity 55 is connected to the deflation interface 30.

[0021] The outer contour of the body 1 is in a columnar structure, and is preferably an elliptical cross-section columnar structure in this embodiment, which can better increase the user's holding comfort.

[0022] The inflation end 2, the installation area, and the deflation end 3 are arranged in sequence, wherein the inflation end 2 is located at the head of the entire body 1, the deflation end 3 is located at the tail of the entire body 1, and the installation area is located between the two.

[0023] The dual-axis head motor 4 is preferably a brushless motor to achieve the function of reducing noise and improving efficiency.

[0024] One of the transmission ends of the double-shaft head motor 4 is connected to the piston rod 9 so that the piston rod 9 reciprocates in the cylinder 10, thereby inflating the inflatable object.

[0025] The other transmission end is provided with fan blades 56. In the present embodiment, the number of the fan blades 56 is specifically seven. In other embodiments, the specific number of the fan blades 56 may be determined according to actual conditions (such as air pump specifications or motor power).

[0026] The fan blades 56 can rotate under the action of the dual-shaft head motor 4, including forward rotation and reverse rotation.

[0027] Specifically, when the dual-axis head motor 4 rotates in one direction, the piston rod 9 reciprocates, thereby realizing the inflation of the inflatable item. The fan blades 56 in this process play a heat dissipation role, and the air flow is discharged from the air release interface 30 through the fan blades 56, thereby playing a cooling effect on the dual-axis head motor 4. Moreover, since the air flow is continuously discharged from the air release interface 30 through the fan blades 56, the air flow inside the entire main body 1 will also be continuously extracted, so the interior of the entire main body 1 will also be cooled. Especially near the cylinder 10.

[0028] When the double-axis head motor 4 rotates in the opposite direction, the piston rod 9 reciprocates. Since there is no need to inflate, the inflation end 2 does not need to be connected to any equipment, and the deflation end 3 can be connected to the items that need to be deflated. The fan blades 56 rotate in the opposite direction under the action of the double-axis head motor 4, so that the gas inside the items is quickly exhausted. The gas in the items will continuously enter the interior of the main body 1 through the fan blades 56 and be discharged from the inflation end 2, thereby achieving heat dissipation while deflation.

[0029] By providing a dual-axis head motor 4 and fan blades 56, the entire air pump can dissipate heat during inflation without adding an additional heat dissipation power mechanism, which not only reduces costs but also saves space occupied by the main body 1; in addition, by controlling the rotation direction of the dual-axis head motor 4, the present application can also achieve rapid deflation of the inflatable device and achieve heat dissipation inside the entire main body 1 during the deflation process. The inflation, deflation and heat dissipation of the entire device use the same power structure, which minimizes the production cost of introducing additional power mechanisms, and can also reduce the space occupied by the entire main body 1, thereby making the overall size of the air pump smaller and easier to carry.

[0030] In some further embodiments, an installation frame 5 is provided between the biaxial head motor 4 and the air release end 3, and a communication cavity 55 is arranged in the installation frame 5.

[0031] A fan blade 56 is arranged in the communication cavity 55. The communication cavity 55 is formed in the installation frame 5. The installation frame 5 is used to form an installation area for the fan blade 56 and also forms an air flow channel.

[0032] The communication cavity 55 also has a certain protective effect on the fan blade 56.

[0033] In some further embodiments, a communication hole 51 is provided at one end of the installation frame 5 facing the biaxial head motor 4. The communication hole 51 communicates the communication cavity 55 and the installation area; the inflation end 2 is provided with a first diversion gap 22, and the first diversion gap 22 communicates the outside of the main body 1 and the installation area; the communication cavity 55, the installation area, and the first diversion gap 22 together form a heat dissipation channel.

[0034] During inflation, the piston rod 9 reciprocates to inflate the device; at the same time, the external air flow is inhaled into the communication cavity 55 through the fan blade 56, enters the installation area through the communication hole 51, and then is discharged to the outside of the main body 1 through the first diversion gap 22 of the air release end 3, so as to dissipate heat from the main body 1 while inflating.

[0035] In some further embodiments, the number of the communication holes 51 is multiple. Some of the communication holes 51 are located in the area of the installation frame 5 outside the area directly facing the biaxial head motor 4 and are arranged circumferentially.

[0036] One end face of the installation frame 5 facing the biaxial head motor 4 is larger than the end face of the biaxial head motor 4. Some of the communication holes 51 are located in the area of the installation frame 5 outside the area directly facing the biaxial head motor 4 and are distributed around the biaxial head motor 4 in a circumferential manner.

[0037] The above settings ensure that whether the air flow enters the communication cavity 55 from the installation area or enters the installation area from the communication cavity 55, the air flow can be fully distributed around the biaxial head motor 4, so as to dissipate heat sufficiently.

[0038] In some further embodiments, the inflation end 2 is provided with an inflation port. An interface limit ring 20 is sleeved on the inflation port. An inflation interface 21 is provided on the interface limit ring 20. The inflation interface 21 is communicated with the air cylinder 10; a first diversion gap 22 is formed between the interface limit ring 20 and the inflation interface 21.

[0039] A first diversion gap 22 is formed between the inflation interface 21 and the interface limit ring 20. During the deflation process, the gas discharged from the inside of the device enters the inside of the main body 1 under the action of the fan blade 56 and will finally be discharged from the first diversion gap 22.

[0040] In some further embodiments, the mounting bracket 5 includes a mounting plate 50, a communication hole 51 is formed in the mounting plate 50, and a second flow guiding gap 57 is provided between the mounting plate 50 and the dual-shaft head motor 4.

[0041] The communication hole 51 is provided on the mounting plate 50. Specifically, the communication hole 51 penetrates through the mounting plate 50.

[0042] A gap, namely the second flow guiding gap 57, is left between the mounting plate 50 and the dual-shaft head motor 4 to prevent partial blockage of the communication hole 51 and affect the circulation of the heat dissipation air flow.

[0043] In some further embodiments, a lining bracket 6 is provided in the installation area. The mounting bracket 5 is connected to one end of the lining bracket 6 facing the air release end 3. An end face gear 91 is rotatably provided inside the lining bracket 6. An eccentric column 90 is provided on the end face gear 91. The piston rod 9 is hinged to the eccentric column 90. A rotating gear 92 is provided at one end of the dual-shaft head motor 4 facing the air inflation end 2. The rotating gear 92 meshes with the end face gear 91.

[0044] The lining bracket 6 is mainly used to support the structure of the entire body 1 to ensure the structural strength of the entire air pump. In addition, it also plays a certain role in isolation and division to separate different structures in the air pump from each other to avoid mutual influence.

[0045] When the dual-shaft head motor 4 rotates, the rotating gear 92 rotates to drive the end face gear 91 to rotate. When the end face gear 91 rotates, it will drive the piston rod 9 to reciprocate inside the cylinder 10 through the eccentric column 90, thereby realizing the inflation of external equipment.

[0046] An open cavity is provided inside the lining bracket 6 to provide a space for arranging the end face gear 91 inside, and at the same time, it plays a certain role in protecting the rotation of the end face gear 91.

[0047] In some further embodiments, a contact column 62 extends vertically from one end face of the lining bracket 6 facing the air release end 3, and a first internal thread hole is provided on the contact column 62; a connecting column 52 extends vertically from one side of the mounting plate 50 facing the air inflation end 2. A contact groove 53 for the contact column 62 to abut against is provided at one end of the connecting column 52 facing the air inflation end 2; a cavity is provided inside the connecting column 52, and the cavity is open at one end facing the air release end 3. A connecting hole 54 is provided at the bottom of the cavity, and the connecting hole 54 is opposite to the first internal thread hole.

[0048] The contact column 62 is abutted and arranged in the contact groove 53 of the connecting column 52. During actual installation, screws can be arranged in the cavity. The screws pass through the connecting hole 54 in sequence and are screwed into the first internal thread hole, thereby realizing the connection between the connecting column 52 and the contact column 62, that is, realizing the connection between the mounting bracket 5 and the lining bracket 6.

[0049] The abutting post 62 is specifically arranged on the mounting plate 50.

[0050] In some further embodiments, the body 1 further includes a housing 11. Along the length direction of the housing 11, a limiting plate 12 and a limiting shaft 13 are arranged inside the housing 11. A limiting surface 60 and a limiting hole 61 are provided on the inner lining frame 6. The limiting plate 12 and the limiting surface 60 are in limiting abutting cooperation with each other, and the limiting shaft 13 is inserted into the limiting hole 61.

[0051] The limiting plate 12 and the limiting shaft 13 are arranged on the inner wall of the housing 11. During actual installation, the limiting plate 12 abuts against the limiting surface 60 on the inner lining frame 6, and the limiting shaft 13 is inserted into the limiting hole 61 in the inner lining frame 6 to realize the connection between the housing 11 and the inner lining frame 6 and ensure the stability of the entire air pump structure.

[0052] In some further embodiments, one end of the limiting hole 61 facing the inflation end 2 is open, a fixing hole is provided at the bottom of the limiting hole 61, and a second internal thread hole is provided at one end of the limiting shaft 13 inserted into the limiting hole 61. The second internal thread hole is opposite to the fixing hole.

[0053] A screw can be arranged in the fixing hole, and the screw meshes with the second internal thread hole, thereby further strengthening the connection strength between the inner lining frame 6 and the housing 11.

[0054] In some other embodiments, a battery 7 and an integrated circuit board 8 are further included. The battery 7 and the integrated circuit board 8 are respectively located on both sides of the inner lining frame 6 to make full and reasonable use of the space inside the entire housing 11 and ensure that the entire air pump structure is compact and small in size.

[0055] In some other embodiments, a type-c interface is provided at the air release end for a type-c connector 300 to be plugged in for charging.

[0056] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
