At present, the battery in the air pump of the inflatable paddle board is usually a non-detachable battery, and a user can only supply power through an external power supply, however, a proper charging power supply is often difficult to find outdoors, and user experience is affected. In addition, the mounting structure of the battery in the inflatable paddle also has the consideration of convenience and reliability in mounting, and is inconvenient in operation once the structure fails or the battery is replaced

In view of this, an air pump device is provided in an embodiment of the present disclosure to solve the problems in the related art.

As shown in fig. 1, a schematic diagram of the combined structure of the air pump device in the embodiment of the present disclosure is shown.

The air pump device 1 includes: an air pump body 10, a fixed connection 11, and a battery power supply unit 12.

The air pump body 10 is provided with an air inlet 103 for communicating with the outside, an air outlet 104 for communicating with an inflating tool, and an air cavity for communicating the air inlet 103 and the air outlet 104. The air pump may include an upper case 101 and a lower case 102, with the air chamber formed between the upper case 101 and the lower case 102. In the example of fig. 1, the air inlet 103 may be provided at the top of the air pump body 10, for example, at the top of the upper housing 101. The air outlet 104 may be disposed on the side of the air pump body 10 in fig. 1, and is formed by splicing two arc concave holes on the connecting edges of the upper casing 101 and the lower casing 102. An inflation driving assembly (see later figures) can be arranged in the air cavity, and the air outlet 104 can be used for corresponding to the air outlet end position of the inflation driving assembly. The upper and lower housings 102 may be configured to facilitate the installation of components such as an internal inflation driving assembly, and also facilitate the installation of the upper housing 101 in conjunction with the fixing connection member 11, however, it should be noted that in other embodiments, the housing structure of the air pump body 10 may be implemented other than the upper and lower housings 102, such as a left and right housing, or an integral housing with an openable and closable cover, and the like, and is not limited to the illustrated embodiment.

The fixing connector 11 may be mounted to the air inlet 103 for being fitted to the air pump body 10 to be fixed to an inflatable tool. Specifically, a mounting position for fixing to the inflatable tool is formed between the fixing connector 11 and the surface of the air pump body 10. For example, a space is formed between the fixing connector 11 and the surface of the air pump body 10 for clamping and fixing the air pump body to a preset portion of the inflatable tool. Illustratively, in fig. 8, the fixing connector 11 and the air inlet 103 of the air pump body 10 are screwed to each other from both sides of the mounting hole of the air pump body 2 so as to be clamped to the air pump body 2. It will be appreciated that the inflatable paddle 2 in fig. 8 is only an example of an inflatable tool, and the air pump device 1 in the embodiment of the present disclosure may be applied to other types of inflatable tools, and is not limited thereto.

The fixing connector 11 is formed with a battery receiving chamber 111. The battery accommodating chamber 111 has both ends penetrating, one end is disposed toward the inside of the air inlet 103 and communicates with the air chamber, and the other end is disposed toward the outside of the air inlet 103 and communicates with the outside.

The battery power supply unit 12 is detachably disposed in the battery accommodating chamber 111, and forms an air flow channel 1111 communicating with two ends of the battery accommodating chamber 111 with a gap between the battery accommodating chamber 111 and the inner wall of the battery accommodating chamber. Through the air flow channel 1111, the outside and the air chamber can be communicated to form an air flow output from the outside to the air outlet 104 through the air inlet 103 and the air chamber for inflation. Illustratively, at least one control key 120, such as a power key, may be disposed on a surface of the battery power supply unit 12 exposed to the battery receiving chamber 111; an air pump running indicator light 122, a charging interface 124, etc. may also be provided. The charging interface 124 includes, but is not limited to, for example, USB, micro USB, TYPE C, lightning interface, or other TYPEs of charging interfaces 124.

Thus, by the cooperation of the fixing connector 11 and the air pump body 10, the fixing of the air pump device 1 to the inflatable tool can be completed, and the battery accommodating cavity 111 which is used for multiplexing the space with the air inlet 103 can be provided to accommodate the battery power supply unit 12, so that the structural space is saved.

The sealing cover 16 is sealingly covered to an end of the air inlet 103 toward the outside for sealing the air inlet 103. The seal cap 16 may be removed when inflation is desired. Illustratively, the sealing cap 16 may be threadably secured to the outer end of the securing coupler 11 toward the air inlet 103. It will be appreciated that the size of the clamping locations may be adjusted according to the size of the threaded connection. The sealing cover 16 may be disposed separately from the fixing connector 11, as shown in fig. 1, and the sealing cover 16 is further attached to the fixing connector 11 via a flexible connector 17 to prevent loss.

As shown in fig. 2, an exploded schematic view of the air pump device 1 in fig. 1 is shown.

In fig. 2, the upper and lower cases 101 and 102 of the air pump body 10 are separated from each other and from the inflation driving assembly 15. The upper shell 101 is mutually separated from the fixed connecting piece 11, the sealing cover 16 and the battery power supply unit 12. Illustratively, a housing seal 106 may also be provided at the contact location between the upper housing 101 and the lower housing 102 to provide a sealed interface of the two housings.

In the example of fig. 2, the air inlet 103 is provided at the top of the upper case, the air inlet 103 is provided to extend into the air pump body 10 in the axial direction (the vertical center line direction), and the inner wall is provided with a first screw portion 131. The inner wall of the air intake 103 includes a first inner wall portion and a second inner wall portion that are disposed in this order in the axial direction and are connected. The first inner wall portion is rendered smaller in radial length deeper into the battery receiving chamber 111 in the axial direction so as to be connected in conformity with the radial length of the second inner wall portion, i.e., perpendicular to the axial direction, e.g., the horizontal direction in the intake port 103 in the drawing. The first threaded portion 131 includes a first threaded section 1311 provided to the first inner wall portion, and a second threaded section 1312 provided to the second inner wall portion. Illustratively, the first thread segments 1311 are a more radially long and sparsely distributed thread distribution and the second thread segments 1312 are a less radially long and finely distributed thread distribution. The fixing connector 11 is provided with a second screw part 115 for screw-coupling with the first screw part 131. It will be appreciated that the second threaded portion 115 includes a third threaded section and a fourth threaded section that are respectively threadedly engaged with the first threaded section 1311 and the second threaded section 1312, respectively, corresponding to the first threaded portion 131. In fig. 2, only the lower fourth thread segment is shown for reasons of view. The location of the first thread segment 1311 may be referred to as a "bone site" and the location of the second thread segment 1312 may be referred to as a "tooth site". When the thread is tightly engaged with the tooth position, the bone position can be sealed; the screw engagement of the bone site can achieve a better sealing effect between the inner wall of the air inlet 103 and the fixed connection 11.

Alternatively, in other embodiments, the structures of the first threaded portion 131 and the second threaded portion 115 may be changed, for example, threads with the same diameter and width may be used, which is not limited to the illustrated embodiment.

In the example of fig. 2, the fixed connection 11 includes a base 116, where the base 116 is provided with an opening therethrough, and a first cavity section 117 and a second cavity section 118 protrude from the opening to opposite sides, respectively; the first and second chamber sections 117 and 118 have through chamber portions, respectively, and communicate through the openings to form the battery accommodating chamber 111; wherein the first cavity section 117 is provided in the air inlet 103, and the surface of the first cavity section 117 is provided with the second thread portion 115. The surface of the second chamber section 118 is provided with a third screw portion 119 for screw-engagement with a fourth screw portion hermetically covered to the outer end of the battery housing chamber 111 toward the air inlet 103. Illustratively, the seal cover 16 may be connected to a collar that is sleeved over the second chamber section 118 by a flexible connection. In addition, a sealing member 18 is disposed between the sealing cover 16 and the second cavity section 118, and the sealing member 18 may be a sealing ring and also is sleeved outside the second cavity section 118.

As an example, in fig. 2 and 3, a plurality of support bars 1181 are protruded on the inner wall of the second cavity section 118 at intervals along the circumferential direction, and the plurality of support bars 1181 serve to support and limit the battery power supply unit 12 on one hand, and on the other hand, an operation space occupied when holding the battery power supply unit 12 is enclosed between the plurality of support bars 1181 and the inner circumferential wall of the battery accommodating cavity 111, so as to provide a space for accommodating fingers when a user takes out the battery to operate. Of course, if the second cavity section 118 shown in fig. 2 is not present, the supporting bars 1181 may also be provided at a section of the upper end opening in the battery receiving cavity 111, which is not limited to this example. In addition, the open end of the air flow channel 1111 communicating with the outside, which is formed by the gap between the battery power supply unit 12 and the inner wall of the capacity housing chamber 111, can be seen more clearly in fig. 3.

In fig. 2, the air pump device 1 further includes a battery holder 19 fixedly disposed in the air pump body 10, the battery holder 19 corresponding to an end of the battery accommodating chamber 111 penetrating into the air inlet 103 to correspond to a bottom position of the battery power supply unit 12. Illustratively, a metal elastic member 191 is disposed on a surface of the battery support 19 facing the bottom of the battery supply unit 12, and the metal elastic member 191 is electrically connected to the bottom of the battery supply unit, and also plays a role in elastically supporting and positioning the battery supply unit 12 by means of elastic force, and can conveniently adjust the position of the battery supply unit in the axial direction of the air inlet 103, so as to facilitate installation.

The inflation driving assembly 15 is located in an air chamber formed between the upper and lower housings 101, 102. Illustratively, the inflation drive assembly 15 may include a suction end, a motor, a fan, a compression chamber, an exhaust end, and the like. The air suction end may be connected to the air cavity, so as to be connected to the outside through an air flow channel 1111 between the battery power supply unit 12 and the air inlet 103, the motor is powered by the battery power supply unit 12, and the motor drives the fan to rotate to suck air from the air suction end and flow out from the air outlet end through the compression cavity, and the air outlet end is disposed at the air outlet 104 and is connected to an inner cavity of the inflatable tool outside the air outlet 104.

In fig. 5, the battery power supply unit 12 is mounted in the battery receiving chamber 111 of the fixed connector 11. As an example, the air pump body is provided with protruding positioning portions 107 on the inner wall around the air inlet 103, and the positioning portions 107 may be exemplified by studs. The battery holder 19 is positioned corresponding to the bottom of the battery power supply unit 12 and is fixed to the positioning portion 107. Specifically, the battery support 19 may be provided with through holes corresponding to the positions of the screw holes on each stud, so that a screw may pass through the through holes to screw into the screw holes of the stud, so as to fix the battery support 19 to the back of the upper case 101. The battery receiving chamber 111 formed by the fixing connector 11 may have a gap between one end (denoted as a) of the air inlet 103 and a surface (denoted as B) corresponding to the position on the battery support 19, so that one end of the air chamber communicating with the air flow channel 1111 is conducted, and the air charging assembly may be communicated with the outside through the air chamber and the air flow channel 1111. Illustratively, the height of the positioning portion 107, i.e. the stud, is set to be higher than the position of the surface C than the surface a in fig. 5, protruding from the end of the fixing connection 11 in the air pump body, so as to form the gap.

At least two clamping grooves 192 are arranged on the inner wall of the battery bracket 19 along the circumferential direction, corresponding to each convex part 123 one by one. For view reasons, only one protrusion 123 and one slot 192 are shown in the drawings, and the other slot and protrusion corresponding thereto are not shown in the drawings, but are not further shown because the structure between each protrusion and the structure between each slot may be the same.

Each card slot 192 includes: a guide segment 1921 open toward one end of the battery unit 12 and extending in the axial direction, and a locking segment 1922 communicating with the other end of the guide segment 1921 and extending in the circumferential direction, such as an "L" shaped locking groove 192 as shown in the figure. Each boss 123 enters one of the guide segments 1921 as the battery unit 12 goes deeper into the air inlet 103 to reach the catch segment 1922 and enters the catch segment 1922 as the battery unit 12 rotates to complete the battery fixation to the battery support 19. As can be appreciated, as shown in fig. 5, the battery holder 19 is mounted to the rear surface of the upper case 101 corresponding to the inner end of the air inlet 103; referring again to fig. 6, the battery unit 12 is placed in the battery accommodating chamber 111 so that the bottom thereof approaches the battery holder 19, so that each protrusion 123 provided on the wall surface of the battery unit 12 is inserted from the open end of each of the clamping grooves 192, and as the battery unit 12 goes deep into the guiding section 1921 to the locking section 1922 of the corresponding clamping groove 192 of the protrusion 123, the bottom of the battery unit 12 presses the metal elastic member 191 to elastically deform, and then rotates the battery unit 12 so that the protrusion 123 is inserted into the locking section 1922 to be limited by the axial movement, and a certain positioning is also obtained in the circumferential direction under the friction force generated by the resilience force of the metal elastic member 191. It will be appreciated that by reversing the above operations, the battery power supply unit 12 can be removed from the battery receiving chamber 111, facilitating battery replacement.

The structure of the control circuit for the operation of the air pump device 1 is described below.

As shown in fig. 7, a schematic circuit configuration of the air pump device 1 in the embodiment of the present disclosure is shown.

A battery control circuit board 128 and a battery body 125 may be disposed within the housing of the battery powered unit 12. The power supply output terminal 1251 of the battery body 125 is electrically connected to the battery control circuit board 128. The power supply output 1251 may include a positive pole and a negative pole connected by wires to the battery control circuit board 128 for supplying power. The battery control circuit board 128 leads out the positive and negative electrode terminals 121, 122 of the battery power supply unit 12. The battery control circuit board 128 may be connected to the two electrode terminals 121 and 122 as wires by a wire or a metal spring plate, respectively, to make conductive contact for controlling external power supply of the battery body 125. The air pump control circuit board 1001 is electrically connected to the two electrode terminals 121, 122 to obtain power supply controlled by the battery control circuit board 128.

As described in the previous embodiments, in fig. 1, the exposed surface of the battery power supply unit 12 may be provided with a logo of at least one control key 120, a charging interface 124, an indicator light 122, etc. The control keys 120 may include a power key. Then, as shown in fig. 7, the battery control circuit board 128 is disposed at a corresponding position below the exposed surface, the battery control circuit board 128 is provided with a micro switch located below the sign of the control key 120, and the battery control circuit board 128 is electrically connected to the charging interface 124, the indicator light 122, and the like. And the battery body 125 is located below the battery control circuit board 128 within the housing of the battery powered unit 12. The power key may activate or deactivate the power supply output of the battery power supply unit 12.

The battery control circuit board 128 also has a first signal interface 1281. The air pump control circuit board 1001 further includes a second signal interface 1101 electrically connected to the first signal interface 1281 to form a signal path between the battery control circuit board 128 and the air pump control circuit board 1001. In some embodiments, the battery power supply unit 12 is provided with a signal sensing part 127 toward the bottom inside the air inlet, and the signal sensing part 127 may be a conductive sheet. The signal sensing part 127 may be provided for contacting the metal elastic member 191 corresponding to the battery holder 19 and contacting the bottom of the battery unit 12 via a conductor (such as a metal housing part at the bottom of the battery unit 12) to form a conductive connection. The metal elastic member 191 may be electrically connected to the air pump control circuit board 1001 by a soldered wire to form the signal path.

In some examples, when the user operates the control key 120, for example, operates the power key, a first electric signal may be generated and transmitted by the battery control circuit board 128 to the air pump control circuit board 1001 through the signal path, so as to control the air pump driving assembly 15 to perform an air pumping action, i.e. the motor starts to drive the fan to rotate. Alternatively, the power key may also function to shut down inflation. For example, after the user presses the power key to start the inflation, the user may press the power key again to generate a second electrical signal to trigger the battery control circuit board 128 to turn off the power supply output of the battery power supply unit 12, so as to achieve that the user actively stops the inflation.

In some examples, since the sealing cover 16 of the air pump device 1 has different states of closing and opening, the corresponding air pump device 1 is stopped in the closed state, and the corresponding air pump device 1 is operable in the open state (inflation may be started using a power key). Accordingly, the corresponding state setting may also be performed by some sensing structure and mechanism between the sealing cap 16 and the battery power supply unit 12. In the example of fig. 2 and 7, the inner side of the sealing cover 16 may be provided with an induction part 161, and the battery power supply unit 12 is provided with an inductor 126, and the inductor 126 is electrically connected to the battery control circuit board 128. The sensor 126 is configured to generate a third electrical signal when sensing the sensing portion 161, and transmit the third electrical signal to the battery control circuit board 128, so that the battery control circuit board 128 turns off the power supply output of the battery power supply unit 12 based on the third electrical signal. Specifically, when the sealing cover 16 is covered on the air inlet 103, the sensing portion 161 is sensed by the sensor 126 in the battery power supply unit 12, and transmits the third electrical signal to the battery control circuit board 128 to cut off the voltage output of the battery power supply unit 12. It will be appreciated that, when the user activates the air pump device 1 to inflate via the power key, the user may stop the inflation of the air pump device 1 by closing the sealing cover 16 to the air inlet 103. When the user needs to inflate using the air pump apparatus 1, the sealing cover 16 is opened, the sensor 126 cannot sense the sensing portion 161 in the sealing cover 16, and the air pump start restriction is naturally released. The user can start the air pump device 1 by operating the power key. In some embodiments, the sensing portion 161 may be, for example, a magnetic metal, and the sensor 126 may include a hall sensor 126.

In some embodiments, the air pump control circuit board 1001 may be further electrically connected to an air pressure sensor 1002, for generating a fourth electrical signal when the sensed air pressure reaches a preset threshold, and sending the fourth electrical signal to the battery control circuit board 128 through the signal path, so that the battery control circuit board 128 turns off the power supply output of the battery power supply unit 12 based on the fourth electrical signal, thereby stopping the air inflation. This way an automatic stopping of the inflation can be achieved.

As shown in fig. 8, a schematic structural view of the inflatable paddle 2 in an embodiment of the disclosure is shown.

The inflatable paddle 2 comprises a paddle body 21, an air pump device 1 as described in the previous embodiments.

The paddle body 21 is provided with an inner cavity, and the inner cavity can be inflated. The preset part of the paddle body 21 is provided with a mounting hole 211 of the air pump device 1.

The air pump device 1 shown in fig. 8 is in an exploded structure, and the first cavity section 117 of the lower side surface of the base 116 of the fixing connection piece 11 of the air pump device 1 enters the mounting hole to be combined with the air inlet 103 of the air pump body 10 (the upper casing 101 in the drawing) of the air pump device 1 in the paddle body in a threaded connection manner so as to fix the air pump device 1 to the paddle body. The air inlet 103 communicates with the outside, and the air outlet 104 communicates with the inside cavity. The inner chamber can be inflated by the operation of the air pump device 1 as before.

In some examples, the inflatable paddle 2 may further include an exhaust valve 3, where the exhaust valve 3 is provided on the paddle body 21 and is fixed to the exhaust port 212 of the paddle body 21. The exhaust valve 3 includes: an air inlet valve port communicated with the inner cavity and an air outlet valve port communicated with the outside. The exhaust valve 3 is operated to be conducted, so that the gas in the inner cavity can be exhausted, and the paddle board is deflated. The exhaust valve 3 and the air pump device 1 may be located, for example, at a proximal end position in the longitudinal direction of the paddle body 21, respectively, to avoid mutual influence.

It should be noted that the structure of the internal air release valve of the inflatable paddle 2 is only an example, and in other embodiments, the air can be exhausted by an external air exhaust device, which is not limited thereto.

The application of the air pump device 1 to an inflatable tool will be described with reference to the previous drawings as an example of a specific application scenario.

When inflation is needed, the sealing cover 16 is opened, a power key on the upper surface of the battery power supply unit 12 is pressed, and the battery power supply unit 12 is electrically connected with a motor of the inflation driving assembly 15. When the motor is operated, air flows from the air flow channel 1111 formed between the battery power supply unit 12 and the battery accommodating cavity 111 into the air cavity of the air pump body 10, and then flows from the air outlet 104 of the air pump body 10 into the interior of the inflatable tool for inflation. Illustratively, the inflation driving assembly 15 may be provided with an air pressure sensor 126 electrically connected to the air pump control circuit board 1001. When the air pressure value in the inflation tool reaches the preset value, the air pressure sensor 126 transmits the air pressure value to the battery control circuit board through the air pump control circuit board 1001 via the signal path, and the power supply output of the battery body 125 is stopped to stop the motor operation, so that the inflation is stopped. Or the user may also stop the inflation by pressing the power key again. Or the user can cover the sealing cover 16, and the air pump is automatically turned off by sensing the air pump through the sensing part 161 in the sealing cover 16 and the sensor 126 in the battery.

During deflation, the paddle is deflated by operating the internal exhaust valve 23 of the inflation tool (e.g., after depression, directly, etc., depending on the configuration of the exhaust valve). Or the air in the paddle board can be sucked out by using a corresponding external exhaust device (such as an external air pump).

In addition, the battery power supply unit 12 realizes a detachable structure, and the taking and placing are realized by the cooperation of each convex 123 on the battery power supply unit 12 and the clamping groove 192 on the battery bracket 19. The detached battery power supply unit 12 may be additionally charged. After the battery power supply unit 12 is fully charged, each protrusion 123 is aligned to each clamping groove 192, and then the installation can be completed by rotating and clamping.
