Description

Technical Field

[0001] This invention relates to the field of outdoor products technology, and more specifically to a portable device for identifying accessories. Background Technology

[0002] Currently, most micro motors on the market are single-head output shafts that drive only a single component, forming single-function products (such as electric toothbrushes, shavers, flashlights, and other small household appliances). Each of these has a relatively simple function and cannot meet more diverse needs.

[0003] Existing dual-output motors or motors can only output power from both heads simultaneously, which is not conducive to use in daily life scenarios and has poor practicality, so they can only be used as standalone tools. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems existing in the prior art and to provide a portable device with multifunctional output and accessory recognition output.

[0005] The technical solution of this invention is as follows:

[0006] A portable device for identifying accessories includes a housing, with a power connector, a pump output connector, and a motor respectively disposed at both ends of the housing. The power connector is connected to an output shaft, and the pump output connector is connected to a pump head.

[0007] The output end of the control motor is connected to the output shaft and the pump head via a clutch to transmit power.

[0008] It also includes power components, which are driven and connected to the output shaft, and pump output components, which are driven and connected to the pump head.

[0009] The power connector is equipped with a detection component used to identify the type of power component.

[0010] The magnets installed inside the power components are matched with the magnetic control sensors of the detection components.

[0011] Different power components use different magnets.

[0012] When the power component is assembled with the output shaft, each magnet in the power component engages with the corresponding magnetic sensor of the power connector, triggering the corresponding magnetic sensor to generate an electrical identification signal and transmit it to the controller.

[0013] The controller is electrically connected to the motor.

[0014] The controller identifies the type of accessory currently installed on the connector based on the electrical identification signal and the type correspondence list.

[0015] The type correspondence list contains the correspondence between each magnet combination and accessory type; the controller identifies the accessory type currently installed on the connector, including:

[0016] The controller obtains the magnet combination of the magnet group on the accessory based on the received electrical identification signals;

[0017] The controller selects the accessory type corresponding to the identified magnet combination from the type correspondence list.

[0018] The different accessories have different numbers of magnets.

[0019] The magnets in the different accessories are different because the order in which the magnets are placed is different.

[0020] The magnetic sensor is a Hall sensor.

[0021] It also includes a bracket and connecting pipes. The motor is installed inside the bracket, and the connecting pipes are installed inside the bracket. When the pump head is installed inside the bracket, the inlet connector of the pump head is connected to one end of the connecting pipe. The two ends of the bracket are connected to the power connector and the pump output connector, respectively. The bracket is installed inside the housing.

[0022] The pump output connector includes a mounting base and a top cover. The pump head is movably fixed between the mounting base and the bracket. The top cover is fixed to the mounting base. The mounting base is provided with mounting holes corresponding to the liquid outlet of the pump head. The mounting base is provided with a magnetic control sensor.

[0023] The power connector includes an output seat, which is provided with an inlet hole, an output shaft and a check valve. The inlet hole is connected to the pump head through a connecting pipe to supply liquid to the pump head. The pump output connector is provided with an outlet hole, which is connected to the output end of the pump head, and the pump head supplies liquid to the outlet hole.

[0024] Beneficial effects:

[0025] A portable device for identifying accessories includes a housing with a power connector, a pump output connector, and a motor at both ends. The power connector is connected to an output shaft, and the pump output connector is connected to a pump head. The output end of the motor is engaged / disengaged with the power output mechanism and the pump output mechanism to transmit power. The device also includes accessories, which are driven to either the output shaft or the pump head. Both the power connector and the pump output connector are equipped with detection components for identifying accessory types. A magnet inside the accessory matches a magnetic sensor in the detection components.

[0026] This invention utilizes a pump connector and a power connector to connect with external accessories. When the external accessories are connected, they cooperate with the clutch mechanism to start the pump output mechanism and the power output mechanism, thereby completing the pump power output or power output. The connection and use are convenient and the application range is wide.

[0027] Simultaneously, by utilizing detection components and magnets, the types of accessories can be accurately identified, and different working modes can be matched according to the types of accessories, making it extremely intelligent and convenient to use. Attached Figure Description

[0048] Example 1

[0049] A portable device for identifying accessories includes a housing with a power connector, a pump output connector, and a motor at both ends. The power connector is connected to an output shaft, and the pump output connector is connected to a pump head. The output end of the motor is engaged / disengaged with the power output mechanism and the pump output mechanism to transmit power. The device also includes accessories, which are driven to either the output shaft or the pump head. Both the power connector and the pump output connector are equipped with detection components for identifying accessory types. A magnet inside the accessory matches a magnetic sensor in the detection components.

[0050] This invention utilizes a pump connector and a power connector to connect with external accessories. When the external accessories are connected, they cooperate with the clutch mechanism to start the pump output mechanism and the power output mechanism, thereby completing the pump power output or power output. The connection and use are convenient and the application range is wide.

[0051] Simultaneously, by utilizing detection components and magnets, the types of accessories can be accurately identified, and different working modes can be matched according to the types of accessories, making it extremely intelligent and convenient to use.

[0052] The device includes a housing, with a power connector 45 and a pump output connector 5 respectively located at both ends.

[0053] The power connector 45 is connected to the power output mechanism, and the pump output connector 5 is connected to the pump output mechanism.

[0054] It also includes a motor 1, whose output end is connected to the power output mechanism and the pump output mechanism respectively to transmit power;

[0055] The power output mechanism includes an output shaft 3; the output shaft 3 is fixed to the power connector 45.

[0056] The pump output mechanism includes a pump head 2, which is fixed to the pump output connector 5.

[0057] This invention utilizes the pump output connector 5 and the power connector 45 to connect with external accessories. When the external accessories are connected, they cooperate with the clutch mechanism to start the pump output mechanism and the power output mechanism, thereby completing the pump power output or power output. The connection and use are convenient and the application range is wide.

[0058] The magnets in different accessories are different.

[0059] When the accessory is assembled with the power connector or pump output connector, each magnet in the magnet group inside the accessory cooperates with the corresponding magnetic control sensor of the connector, triggering the corresponding magnetic control sensor to generate an electrical identification signal and transmit it to the controller.

[0060] The controller is electrically connected to the motor.

[0061] The controller identifies the type of accessory currently installed on the connector based on the electrical identification signal and the type correspondence list.

[0062] The type correspondence list contains the correspondence between each magnet combination and accessory type; the controller identifies the accessory type currently installed on the connector, including:

[0063] The controller obtains the magnet combination of the magnet group on the accessory based on the received electrical identification signals;

[0064] The controller selects the accessory type corresponding to the identified magnet combination from the type correspondence list.

[0065] The different accessories have different numbers of magnets.

[0066] The magnets in the different accessories are different because the order in which the magnets are placed is different.

[0067] The magnetic sensor is a Hall sensor or a reed switch.

[0068] The pump output connector 5 is equipped with a clamping mechanism for connecting the accessories to the pump head 2 for output.

[0069] The power connector 45 is equipped with an assembly mechanism for connecting the accessories to the output shaft 3 for output.

[0070] It includes a first clutch mechanism and a second clutch mechanism. One output end of the motor 1 is connected to the output shaft 3 through the second clutch mechanism, and the other output end of the motor 1 is connected to the pump head 2 through the first clutch mechanism.

[0071] The first clutch mechanism includes a connector for connecting the output end of the motor 1 and the pump head 2. When the pump head 2 moves toward the motor 1, the pump head 2 is driven to connect with the output end of the motor 1 through the connector.

[0072] The overall movement of the pump head 2 allows for easy engagement and disengagement of the clutch. The drive shaft of the pump head 2 is connected to the output end of the motor 1 to achieve power transmission. The pump head 2 can work in conjunction with the reset mechanism to achieve reset by pressing and springing back. This structure is relatively simple, has low maintenance costs, and is very convenient to use.

[0073] The second clutch mechanism includes a connector for connecting the output end of the motor 1 and the output shaft 3. When the output shaft 3 moves toward the motor 1, the output shaft 3 is driven to connect with the output end of the motor 1 through the connector.

[0074] The clutch is achieved by driving the output shaft 3 to move and thus driving the connection with the output end of the motor 1. That is, when the output shaft 3 is in the pressed state, the drive connection is established, and when it is in the released state, it is disengaged from the motor 1. This saves the wear caused by normal connection and is also extremely safe, as it does not move when the load is removed.

[0075] The movement of output shaft 3 and pump head 2 can enable the drive device to have two output states simultaneously, that is, the drive device can pump out liquid at the same time, or the output shaft 3 can output power to rotate.

[0076] The motor 1 moves, and the first clutch mechanism includes a connector for connecting the output end of the motor 1 and the pump head 2. The second clutch mechanism includes a connector for connecting the output end of the motor 1 and the output shaft 3. When the motor 1 moves toward the pump head 2, the drive shaft of the pump head 2 is driven to the output end of the motor 1 through the connector. When the motor 1 moves toward the output shaft 3, the output end of the motor 1 is driven to the output shaft 3 through the connector.

[0077] The present invention can also achieve clutch engagement by moving the motor 1, that is, by adjusting the position of the motor 1 to achieve clutch engagement with the pump head 2 or the output shaft 3.

[0078] The present invention can also integrate the clutch connector on the motor 1, the pump head 2 or the output shaft 3. The clutch connector includes a connector 101 assembled at the output end of the motor 1. The drive shaft of the pump head 2 is inserted into the connector 101 to achieve a drive connection. A bushing 303 is integrated at the end of the output shaft 3. The output end of the motor 1 is connected to the bushing 303 of the output shaft 3 to achieve a clutch connection.

[0079] The output end of motor 1 is connected to the drive shaft via an adapter. The adapter can adjust the position of the drive shaft, allowing the position of the drive shaft to be set as needed and to match different accessories.

[0080] The adapter is configured as a gear transmission mechanism to connect the output end of motor 1 and output shaft 3.

[0081] When this clutch method is used, there is only one output state, and the structures of pump head 2 output and output shaft 3 output are fixed, which greatly increases safety and robustness.

[0082] The pump head 2 and the output shaft 3 of the motor 1 can be connected by various connecting parts to achieve the clutch state. Any method that can achieve the drive connection can be used. For example, a bushing 303 can be used to connect the drive shaft of the motor 1 and the pump head 2. One end of the bushing 303 is connected to the output end of the motor 1, and the other end is connected to the drive shaft of the pump head 2, which is used to transmit the power of the motor 1 to the pump head 2.

[0083] The pump head 2 of this application is a driving part for conveying liquid, that is, a part of the structure of a water pump. It can be driven by a diaphragm pump or a piston pump, etc. The output end of the motor 1 is connected to the drive shaft of the pump head 2 to transmit power and drive the pump head 2 to move, so that the liquid is sprayed out through the liquid outlet 202 of the pump head 2.

[0084] An elastic reset mechanism is provided, which is connected to the pump head 2. When the pump head 2 moves toward the motor 1, it compresses the elastic reset mechanism, which drives the pump head 2 to reset, and the pump head 2 disengages from the motor 1.

[0085] The elastic reset mechanism includes a spring 8, which is disposed between the pump head 2 and the motor 1. When the pump head 2 is subjected to force, it compresses the spring 8, reducing the distance between the pump head 2 and the motor 1. The drive shaft of the pump head 2 is engaged with the output end of the motor 1. When the spring 8 expands, the drive shaft of the pump head 2 disengages from the output end of the motor 1, leaving the engaged / disengaged state.

[0086] The pump head 2 is installed inside the pump output connector. The pump head 2 is stuck inside the pump output connector and is in a compressed state. Together with the spring 8, it forms an elastic deformation state. When the external pressure moves the pump head 2, the output can be completed.

[0087] A magnetic reset mechanism is provided, which is connected to the output shaft 3. When the output shaft 3 moves toward the motor 1, the magnetic reset mechanism attracts the output shaft 3 to disengage from the motor 1.

[0088] The magnetic reset mechanism includes a magnetic ring 301 and an iron plate 302. The magnetic ring 301 is fixed to the output shaft 3, and the iron plate 302 is fixed to the output base. When the output shaft 3 moves and disengages from the output end of the motor 1, the magnet attracts the iron plate 302 to drive the output shaft 3 to reset.

[0089] The magnetic reset mechanism has a simple structure and is used to reset the drive shaft. The magnetic ring 301 also serves to prevent the output shaft from coming off the mounting base.

[0090] It also includes a bracket 7 and a connecting pipe 201. The motor 1 is disposed inside the bracket 7, and the connecting pipe 201 is disposed inside the bracket 7. When the pump head 2 is disposed inside the bracket 7, the liquid inlet connector 203 of the pump head 2 is connected to one end of the connecting pipe 201. The two ends of the bracket 7 are respectively connected to the power connector 45 and the pump output connector 5. The bracket 7 is disposed inside the outer casing 6.

[0091] The connecting pipe 201 is integrated by the bracket 7, in which the pump output connector 5, pump head 2, motor 1, output shaft 3, and power output connector 101 are arranged in sequence, which greatly reduces the volume.

[0092] The bracket 7 includes a motor mounting position, a control circuit board 701 mounting position, and a battery 703 mounting position, which are arranged sequentially along the axial direction of the bracket 7. The motor 1 is installed in the motor mounting position, and the pump head 2 is located above the motor 1. A spring 8 is provided between the pump head 2 and the motor 1. A pump output connector 5 and a top cover 507 are provided above the pump head 2. An output shaft 3 is provided below the motor 1. The output shaft 3 is fixed to a power connector 45. Both the power connector 45 and the pump output connector 5 are fixed to the bracket 7 by bolts.

[0093] The top cover 507 can seal the pump output connector 5 to prevent debris from entering the outlet hole 202.

[0094] The pump output connector 5 includes a mounting base and a top cover 507. The pump head 2 is movably fixed between the mounting base and the bracket 7. The top cover 507 is fixed to the mounting base. The mounting base is provided with a mounting hole 506 corresponding to the liquid outlet hole 202 of the pump head 2.

[0095] It also includes a clamping mechanism, which includes a nozzle clamping member 503 disposed above the mounting base, a spring member 505, and a fixing sleeve 501 disposed on the pump head 2. A part of the nozzle clamping member 503 cooperates with the fixing sleeve 501 to form a clamping part. The nozzle clamping member 503 abuts against the spring member 505. When the nozzle clamping member 503 is pressed, the nozzle clamping member 503 is released from the clamping state of the fixing sleeve 501.

[0096] The clamping mechanism also includes a fixing hole 502 and a clamping button 504 provided in the mounting base. The clamping button 504 is inserted into the fixing hole 502. When the clamping button 504 is pressed, the clamping button 504 moves along the fixing hole 502, and the nozzle clamping member 503 releases the clamping state of the spring member 505 and the fixing sleeve 501.

[0097] The power connector 45 includes an output seat, which is provided with an inlet port 402, an output shaft 3 and a check valve 403. The inlet port 402 is connected to the pump head 2 through a connecting pipe 201 to supply liquid to the pump head 2. The pump output connector 5 is provided with an outlet port 202, which is connected to the output end of the pump head 2, and the pump head 2 supplies liquid to the outlet port 202.

[0098] The output seat has a shaft mounting position for mounting the output shaft 3. A sealing ring 401 is provided in the shaft mounting position. The sealing ring 401 is sealed to the output shaft 3 to keep the inside and outside of the mounting seat sealed during the linear or rotational motion of the output shaft 3, preventing water from entering the output shaft 3.

[0099] The liquid inlet 402 is also equipped with a filter screen to filter impurities.

[0100] An air cushion 404 is provided on the inner side of the check valve 403 to close the check valve 403.

[0101] The power connector 45 is fixedly connected to the bracket 7 by a connecting stud 405.

[0103] It also includes a straight-insertion buckle that matches the output seat. When the straight-insertion buckle is inserted into the directional groove 407, it drives the output shaft 3 to move.

[0104] The straight-insertion buckle is a power output accessory, which includes a body. The shape of the body is adapted to the inside of the power connector. Its surface is provided with a recessed hole corresponding to the output shaft 3. The recessed hole is used to expose the output shaft 3 and press the output shaft 3 to displace the output shaft 3 and engage with the clutch drive of the motor 1.

[0105] The outer periphery of the straight-insertion buckle is provided with a clip and an insert plate. The insert plate is inserted into the directional groove 407, and the clip engages with the threaded interface 406 in the output seat.
