They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] As shown in Figures 1 and 2, a handheld cleaning machine 100 includes: a cleaning head 200, which has a motor 210 and a water spray valve 220, wherein the cleaning head 200 is used to spray out cleaning liquid.

[0037] The handle 300 is located below the cleaning head 200. The bottom of the handle 300 has a battery installation interface 310, and the front of the handle 300 has a rotatable trigger 320.

[0038] The trigger 320 is provided with a locking component 330, and the handle 300 is provided with a groove 340. The locking component 330 is selectively engaged with the groove 340.

[0039] The locking assembly 330 is located below half the height of the trigger 320; the trigger 320 has a switch protrusion 321, which is located above half the height of the trigger 320, thus preventing accidental operation of the switch protrusion 321 when the locking assembly 330 is operated with one hand.

[0040] Battery pack 400 is mounted on battery mounting interface 310. Although it is mentioned that motor 210 and water spray valve 220 are inside cleaning head 200, the connection between motor 210 and water spray valve 220 and how they work together to spray cleaning liquid are conventional technologies and will not be elaborated here.

[0041] The use of battery pack 400 to power cleaning machine 100 is a standard technology and will not be elaborated upon here.

[0042] Furthermore, the groove 340 is fixed to the front of the handle 300 and extends in the vertical direction. The groove 340 is provided to limit the movement of the trigger 320. The locking assembly 330 rotates on the plane of rotation, and by rotating the locking assembly 330 to different positions, the movement of the trigger 320 in the front-rear direction is limited.

[0043] As shown in Figures 3 and 4, the locking component 330 has two states: locked and unlocked, corresponding to a locked position and an unlocked position, respectively. When the locking component 330 rotates to the locked position within the rotation plane, it engages with the groove 340, and the trigger 320 is in the locked state, unable to move forward or backward. When the locking component 330 rotates to the unlocked position within the rotation plane, it disengages from the groove 340, and the trigger 320 is in the unlocked state, allowing it to move forward or backward in both directions.

[0044] As shown in Figure 7, the locking assembly 330 includes a knob 331 and a locking member 332. The trigger 320 has an outer surface, which includes a pressing surface 322, a first side surface 323, and a second side surface 324. The pressing surface 322 is for pressing by the operator's finger, and the pressing surface 322 is provided with a through hole 325. The knob 331 passes through the through hole 325 and is interference-fitted with the locking member 332. The locking member 332 is selectively engaged with the groove 340.

[0045] Furthermore, the knob 331 has a knob head 333 and a support post 334, wherein the knob head 333 is operated by the operator, and the knob head 333 rotates about the support post 334 to form a plane of rotation, wherein the plane of rotation is perpendicular to the first side 323 and the second side 324 of the trigger 320. The locking member 332 has a mounting portion 335 and a locking portion 336, the support post 334 is interference-fitted to the mounting portion 335, and the locking portion 336 is selectively snapped into the groove 340.

[0046] The support column 334 and the knob head 333 are integrally formed. The support column 334 supports the knob head 333, so that the knob head 333 can rotate counterclockwise or clockwise on the pressing surface 322 of the trigger 320 under the action of the finger.

[0047] Furthermore, the locking part 336 includes a circular main body part 337 and a flange part 338, the flange part 338 protruding radially from the circular main body part 337, and the flange part 338 selectively engaging with the groove 340.

[0048] The knob head 333 has dual operating parts 339 and an arc-shaped positioning part 341, suitable for left- and right-handed operation. The positioning part 341 cooperates with the arc-shaped groove 326 of the trigger 320 to achieve precise positioning. The knob head 333 has operating parts 339 and positioning parts 341. The pressing surface 322 is provided with a limit groove 327 and a positioning groove 326. The positioning part 341 is positioned in the positioning groove 326. The operating part 339 protrudes from the radial surface of the knob head 333. The positioning part 341 is arc-shaped.

[0049] When the user grips the trigger 320 and rotates the operating part 339 counterclockwise with their finger, the positioning part 341 disengages from the positioning groove 326, and the flange part 338 disengages from the recess 340. At this time, the trigger 320 is in the unlocked position. With the trigger 320 activated, the motor 210 starts.

[0050] When the user holds the trigger 320 and rotates the operating part 339 clockwise with their finger, the positioning part 341 disengages from the positioning groove 326, and the flange part 338 engages with the recess 340. At this point, the trigger 320 is in the locked position. The trigger 320 cannot be triggered, and the motor 210 cannot be started.

[0051] Furthermore, the knob head 333 has a circular body, the positioning part 341 has an arc-shaped surface, and the positioning groove 326 is an arc-shaped groove. In the locked position, the arc-shaped surface is positioned in the arc-shaped groove, and in the unlocked position, the arc-shaped surface disengages from the arc-shaped groove.

[0052] As shown in Figure 8, the side of the trigger 320 also includes a first side surface 323 and a second side surface 324. The two sides of the pressing surface 322 are the first side surface 323 and the second side surface 324, respectively. The pressing surface 322, the first side surface 323, and the second side surface 324 together form the trigger surface. The first side surface 323 is parallel to the second side surface 324, and the axis of rotation of the support column 334 is parallel to the first side surface 323, that is, the plane of rotation is perpendicular to the side of the trigger 320.

[0053] Furthermore, there are two operating parts 339 and two flange parts 338, so that whether the handheld cleaning machine 100 is held with the left hand or the right hand, it can be unlocked and locked with fingers, which meets ergonomic requirements and is more convenient for operators with different usage habits.

[0054] The operating method of this utility model is as follows:

[0055] 1. Unlocking and starting: As shown in Figure 5, hook your finger on the trigger 320, and rotate the knob 331 operating part 339 counterclockwise with your thumb / index finger to disengage the locking part 332 flange part 338 from the groove 340. The trigger 320 rotates backward to trigger the motor 210, and the water spray valve 220 works synchronously.

[0056] 2. Locking and stopping: As shown in Figure 6, when the motor 210 is running, rotate the knob 331 counterclockwise, the flange 338 will engage with the groove 340, the trigger 320 will lock and cannot be rotated, and the motor 210 will be powered off and stopped.

[0057] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
