[0038] Embodiment 1

[0039] A portable tool for a clutch pump, comprising a housing 5, a mounting seat 4 provided on the housing 5, a motor 1 provided in the housing 5, and a pump output mechanism. The pump output mechanism includes a pump head 2. The pump head 2 is fixed to the mounting seat 4, and the output end 101 of the motor 1 is in clutch connection with the pump head 2.

[0040] The present invention utilizes the clutch mechanism to drive the connection or disconnection between the pump output mechanism and the motor 1, which can be used conveniently. By fixing the accessories of the pump output mechanism through the mounting seat 4, structures such as a nozzle, a dental irrigator, an atomizer, etc. can conveniently cooperate with the pump output mechanism to realize various uses of the water circuit, with a wide range of uses and diverse functions.

[0041] The present invention can adopt various forms to drive the pump head 2 or the motor 1 to achieve clutch connection.

[0042] When the pump head 2 moves towards the motor 1, the output shaft 212 of the pump head 2 is inserted into the output end 101 of the motor 1 and is drivingly connected to the motor 1.

[0043] The pump head 2 can be conveniently drivingly connected as a whole. The power transmission is realized by connecting the output shaft 212 of the pump head 2 to the output end 101 of the motor 1. The pump head 2 can cooperate with the reset mechanism as a whole to realize the reset in the way of pressing and bouncing back. Such a structure is relatively simple, with low maintenance cost and very convenient to use.

[0044] When the pump head 2 moves, the driving device can have two output states at the same time, that is, the driving device can output liquid by the pump and can also drive the output shaft 8 to output power and rotate.

[0045] When the motor 1 moves towards the pump head 2, the output shaft 212 of the pump head 2 is inserted into the output end 101 of the motor 1 and is drivingly connected to the motor 1.

[0046] The present invention can also realize the clutch by the movement of the motor 1, that is, the clutch connection between the motor 1 and the pump head 2 is realized by adjusting the position of the motor 1.

[0047] When using the portable tool in this application, the motor 1 is fixed in the bracket 3, that is, the up and down position of the motor 1 can be adjusted to realize the clutch connection with the pump head 2.

[0048] When adopting this clutch method, there is only one output state, and the structures of the output of the pump head 2 and the output of the output shaft 8 are both fixedly arranged, greatly increasing the safety and firmness.

[0049] The clutch state of this application is realized through a connecting piece. The connecting piece of the first clutch mechanism is to connect the pump head 2 and the motor 1. The output shaft 212 of the pump head 2 and the motor 1 can adopt a variety of connecting pieces to realize it. Any way that can realize its driving connection can be adopted. For example, a shaft sleeve is used to connect the output end 101 of the motor 1 to the output shaft 8 of the pump head 2. One end of the shaft sleeve is connected to the output end 101 of the motor 1, and the other end is connected to the output shaft 8 of the pump head 2 to transmit the power of the motor 1 to the pump head 2.

[0050] Adopting the direct drive connection method, that is, the driving direction does not change. The output end 101 of the motor 1 and the driving chain of the pump head 2 are on the same axis, with low transmission loss and more energy-saving.

[0051] The present invention realizes the clutch state connection through a connection structure.

[0052] It further includes a connection structure, which includes a connection body 102 and a drive mounting position 103. The connection body 102 is fixedly connected to the output end 101 of the motor. The drive mounting position 103 is used to accommodate the output shaft 212, and is inclined when the output shaft 212 extends into the drive mounting position 103.

[0053] The drive mounting position 103 is eccentrically arranged on the connection body 102.

[0054] The upper end of the drive mounting position 103 is provided with an inclined surface 104, which inclines from the upper end of the drive mounting position 103 into the drive mounting position 103. When the drive shaft 8 (original claim six) of the pump head 2 is inserted, it contacts the inclined surface 104.

[0055] The eccentric arrangement deflects the output shaft 212 of the pump head 2, making the operation of the diaphragm pump very convenient, with low noise and stable flow.

[0056] The pump head 2 includes a diaphragm pump body and an output shaft 212. The diaphragm pump body includes a liquid inlet joint 206, a leather cup assembly 210, a traction frame 211 and a cavity. The output shaft 212 is drivingly connected to the traction frame 211, and the traction frame 211 is drivingly connected to the leather cup assembly 210 to drive the leather cup assembly 210 to move in the cavity. A water inlet groove 207 communicated with the liquid inlet joint 206 is arranged in the cavity, and the leather cup assembly 210 pumps the liquid in the water inlet groove 207 out through the liquid outlet hole 208.

[0057] The cavity includes an upper shell 203, a middle shell 204, a lower shell 205 and a cover 202. The output shaft 212 and the traction frame 211 are arranged in the lower shell 205. The leather cup assembly 210 is arranged between the upper shell 203 and the middle shell 204. The water inlet groove 207 is arranged in the cover 202. The cover 202 and the upper shell 5203 are sealed by a pump head 2 sealing sheet 209, and the sealing sheet 209 is provided with a notch adapted to the outer shape of the leather cup assembly 210.

[0058] Through the above structural design, the direction of the liquid inlet joint 206 can be set downward to be able to communicate with the connecting pipeline 201, and the overall volume is small.

[0059] An elastic reset component is provided, which is arranged between the pump head 2 and the motor. When the pump head 2 moves towards the motor, the elastic reset mechanism 6 is compressed. When the pump head 2 disengages from the motor, the elastic reset mechanism 6 drives the pump head 2 to reset.

[0060] The elastic reset mechanism 6 includes a spring. The spring is arranged between the pump head 2 and the motor 1. When the pump head 2 is forced to move, it compresses the spring and reduces the distance from the motor 1. The output shaft 212 of the pump head 2 is in a clutch connection with the output end 101 of the motor 1. When the spring expands, the output shaft 212 of the pump head 2 disengages from the output end 101 of the motor 1 and leaves the clutch state.

[0061] The pump head 2 is arranged in the pump output joint. The pump head 2 is stuck in the pump output joint and is in a compressed state, forming an elastic deformation state together with the spring. When the outside presses the pump head 2 to move, the output can be completed.

[0062] The pump head 2 is in a clutch connection or disengagement with the motor 1 along the axial direction of the housing 5.

[0063] It further includes a bracket 3. The motor 1 is arranged in the bracket 3. It also includes a connecting pipeline 201. The connecting pipeline 201 is arranged in the bracket 3.

[0064] It further includes a control button 302 and a control circuit board 301. The control button 302 is arranged on the outer side of the housing body and is electrically connected to the control circuit board 301 in the housing body. The control circuit board 301 is fixed to the bracket 3 and is connected to the motor 1.

[0065] The control button 302 and the control circuit board 301 are connected to the motor 1. By setting the control button 302 on the housing body, it is convenient to control the opening and closing of the motor 1 and realize the start and stop of the portable tool.

[0066] The upper end of the pump head 2 abuts against the mounting seat 4, and a spring is arranged between the pump head 2 and the motor 1.

[0067] It further includes a clamping mechanism. The clamping mechanism includes a nozzle clamping part 404 arranged above the mounting seat 4, a spring assembly 405, and a fixed sleeve 401 arranged on the pump head 2. A part of the nozzle clamping part 404 cooperates with the fixed sleeve 401 to form a clamping part. The nozzle clamping part 404 abuts against the spring assembly 405. When the nozzle clamping part 404 is pressed, the clamping state between the nozzle clamping part 404 and the fixed sleeve 401 is released.

[0068] The clamping mechanism further includes a fixing hole 402 arranged on the mounting seat 4 and a clamping button 403. The clamping button 403 is stuck into the fixing hole 402. When the clamping button 403 is pressed, the clamping button 403 displaces along the fixing hole 402, and the nozzle clamping part 404 presses the spring assembly 405 to release the clamping state with the fixed sleeve 401.

[0069] When the nozzle is installed on the clamping mechanism, it is inserted into the mounting seat 4 and communicated with the liquid outlet hole 208. At the same time, the clamping state can stably maintain the nozzle in a pressing state on the pump head 2, thereby ensuring the connection state between the pump head 2 and the motor 1.
