Accordingly, in the process of using thehandheld cleaning apparatus 200, the operation of theoperation wrench 250 can enable the start control of thewater pump assembly 220 and the control of the conduction state of thewater pump assembly 220 and the external water pipe to be synchronously implemented, and further, the start control of thewater pump assembly 220 and the conduction of the external water pipe can be synchronously controlled by a single operation of a user through such a setting mode, so that the structure of thehandheld cleaning apparatus 200 can be simplified, the operation steps can be simplified, and further, the situation of misoperation caused by excessive operation steps can be avoided, thereby improving the operation safety.

It should be noted that, based on the above, when the hand-heldcleaning apparatus 200 is provided, themain body 210 is rotatably connected with theoperation wrench 250, and the corresponding installation positions for installing thewater pump assembly 220, theelectric control switch 230 and thevalve body assembly 240 are provided in themain body 210, and since theelectric control switch 230 and thevalve body assembly 240 are located on the same side of theoperation wrench 250, and thevalve body assembly 240 is connected with thewater pump assembly 220 to control the water intake of thewater pump assembly 220, when thewater pump assembly 220, theelectric control switch 230 and thevalve body assembly 240 are provided, they are relatively located on the same side of theoperation wrench 250;

in addition, in order to facilitate the user's operation, themain body 210 may be provided in a shape that is convenient for the user to hold when themain body 210 is provided. In this embodiment, referring to fig. 1-4, when the water pump assembly 220 is provided, the water pump assembly 220 includes a pump body 221, a motor 222 and a power supply 223; wherein, the power supply 223 may be an external power supply 223 or an internal power supply 223, and when the internal power supply 223 is configured, the power supply 223 may be detachably connected with the main body 210, so as to charge the power supply 223, and when the power supply 223 is installed, the power supply 223 is located on a side of the main body 210 facing away from the operating wrench 250, so as to avoid the power supply 223 installed on the main body 210 from interfering with the operation of the operating wrench 250; the pump body 221, the motor 222 and the power supply 223 are all connected with the main body 210, the motor 222 is in transmission connection with the pump body 221, and the motor 222 is electrically connected with the power supply 223 through the electric control switch 230; thus, when the electric control switch 230 is used to control the water pump assembly 220 to be started or shut down, it means that the electric control switch 230 can control the on or off state of the motor 222 and the power supply 223; the valve body assembly 240 is used to make the water pump assembly 220 conduct or block with the external water pipe, and when the external water pipe is connected with the handheld cleaning device 200, the valve body assembly 240 can conduct or block the water inlet of the pump body 221 with the external water pipe; thus, as can be seen from the foregoing, when the user operates the handheld cleaning device 200, the operation wrench 250 is enabled to act, and thus the motor 222 and the power supply 223 can be electrically conducted, so that the motor 222 can drive the pump body 221 to work, and the pump body 221 and the external water pipe to be conducted, and it is worth noting that the technical scheme is that the effect of water and electricity linkage is achieved by operating the wrench 250 to link the valve body assembly 240 and the micro switch, rather than synchronous control of water and electricity start, during the water and electricity start, the valve body assembly 240 can be started before the motor 222, or the valve body assembly 240 is started later than the motor 222, or the motor 222 and the valve body assembly 240 are started simultaneously, and in the embodiment, in order to avoid idle running of the motor 222, the motor 222 is started later than the valve body assembly 240.

Further, referring to fig. 1-6, in the present embodiment, theoperation wrench 250 is rotatably connected to themain body 210, in such a way that theoperation wrench 250 can rotate relative to themain body 210 under the action of external force, so as to trigger theelectric control switch 230 and thevalve body assembly 240. It should be noted that, when the operatingwrench 250 is installed, one end of the operatingwrench 250 is rotatably connected to themain body 210, and the other end of the operatingwrench 250 is used for triggering theelectric control switch 230 and thevalve body assembly 240.

Specifically, in the present embodiment, a pivot axis perpendicular to the plane of the operatingwrench 250 is provided at the rotation center of the operatingwrench 250, and when thevalve body assembly 240, theelectric control switch 230 and the operatingwrench 250 are configured, theelectric control switch 230 and thevalve body assembly 240 are located on the same side of the pivot axis of the operatingwrench 250; an accommodating space is formed between the front side of the operatingwrench 250 and the rear side of thewater pump assembly 220 in themain body 210, anelectric control switch 230 is arranged in the accommodating space, and theelectric control switch 230 is a micro switch;

when the operatingwrench 250 is arranged, the upper part of the operatingwrench 250 is positioned in themain body 210 and behind thewater pump assembly 220, the middle part of the operatingwrench 250 is positioned in themain body 210 and is provided with a first connectingpart 251 for actuating theelectric control switch 230 and a second connectingpart 252 for actuating thevalve body assembly 240, and the lower part of the operatingwrench 250 is exposed out of themain body 210 for starting operation; the pivot shaft is located at the upper portion of the operatingwrench 250. In addition, in order to enable theoperation wrench 250 to drive theelectric control switch 230 and thevalve body assembly 240 to act when rotating relative to themain body 210, theoperation wrench 250 is provided with afirst connection portion 251 and asecond connection portion 252, and thefirst connection portion 251 and thesecond connection portion 252 are located at one side of theoperation wrench 250 close to thewater pump assembly 220; the hand-heldcleaning apparatus 200 further includes apull rod 261, one end of thepull rod 261 is connected with thesecond connection portion 252, and the other end of thepull rod 261 is connected with thevalve body assembly 240; the first connectingpart 251 is used for actuating theelectric control switch 230, and the second connectingpart 252 is used for connecting thevalve body assembly 240 through thepull rod 261; wherein the electronically controlledswitch 230 is located between the operatingwrench 250 and thewater pump assembly 220.

Thus, with the above-described configuration, thefirst connection portion 251 and thesecond connection portion 252 can be interlocked with each other when theoperation wrench 250 and themain body 210 are rotatably connected. Also, when the operatingwrench 250 is rotated with respect to themain body 210, thesecond connection portion 252 may be connected to thevalve body assembly 240 through thepull rod 261.

Based on the above configuration, when thefirst connection portion 251 is provided, thefirst connection portion 251 includes the first mountinggroove 253 opened to the operatingwrench 250; in this structure, theelectric control switch 230 includes abody 231 and atrigger lever 232, thetrigger lever 232 is connected to thebody 231, and thetrigger lever 232 is accommodated in the first mountinggroove 253; in this embodiment, theelectric control switch 230 is a micro switch, and thetrigger lever 232 is an action reed of the micro switch. Thus, the operatingwrench 250 is configured to rotate relative to themain body 210 under the action of external force, and trigger thetrigger lever 232 located in the first mountinggroove 253 during rotation, so that the circuit of thewater pump assembly 220 is started. That is, when theoperation wrench 250 rotates relative to themain body 210 under the action of external force, there is a relative movement between theoperation wrench 250 and thetrigger rod 232, and as theoperation wrench 250 continues to move along the same direction, the inner wall of the first mountinggroove 253 abuts against thetrigger rod 232 and drives thetrigger rod 232 to move, so as to trigger thetrigger rod 232 located in the first mountinggroove 253, and further, themotor 222 is powered on, and thepump body 221, i.e. thewater pump assembly 220, is started.

Further, referring to fig. 1-9, in the present embodiment, thevalve body assembly 240 includes avalve body 241 and avalve rod 242; thevalve body 241 is provided with amovable channel 244, awater guide channel 245 and awater inlet channel 246, wherein themovable channel 244 is communicated with thewater guide channel 245 and thewater inlet channel 246, thewater guide channel 245 is communicated with thewater pump assembly 220, and thewater inlet channel 246 is used for being communicated with a waterway of an external water pipe; thevalve rod 242 is movably connected with thevalve body 241, and at least part of thevalve rod 242 is accommodated in themovable channel 244;

the second connectingportion 252 includes a bar-shapedhole 254 opened in the operatingwrench 250; one end of thepull rod 261 is movably matched with the strip-shapedhole 254, and the other end of thepull rod 261 is connected with thevalve rod 242; the operatingwrench 250 is used for rotating relative to themain body 210 under the action of external force, so as to drive thepull rod 261 to move, and further enable thevalve rod 242 to conduct or block thewater guide channel 245 and themovable channel 244.

Thus, in this configuration, since one end of thepull rod 261 is movably engaged with the bar-shapedhole 254, the other end of thepull rod 261 is connected with thevalve body assembly 240; therefore, when the operatingwrench 250 moves relative to themain body 210 under the action of external force, thepull rod 261 is driven to move, so that thevalve rod 242 located in themovable passage 244 moves relative to themovable passage 244, and thewater guide passage 245 is connected to themovable passage 244, so that the external water pipe is communicated with thewater pump assembly 220 through thewater inlet passage 246, themovable passage 244 and thewater guide passage 245.

It should be noted that, first, since the operatingwrench 250 is rotatably connected to themain body 210, in order to limit the movement of thepull rod 261 relative to themain body 210 when the operatingwrench 250 moves to drive thepull rod 261, thehandheld cleaning apparatus 200 further includes aguide 262 connected to themain body 210, and theguide 262 is used for guiding thepull rod 261 to slide. By the way, thepull rod 261 can be made to move in themain body 210 in a linear manner under the driving action of the operatingwrench 250;

secondly, when thevalve rod 242 located in thewater guiding channel 245 moves relative to thewater guiding channel 245, the mode of locating thevalve rod 242 in themovable channel 244 to seal or open the joint of thewater guiding channel 245 and themovable channel 244 is adopted, and when thevalve rod 242 moves relative to themovable channel 244, the joint of thevalve rod 242 and themovable channel 244 leaks, so that thevalve rod 242 is sleeved with the sealingsleeve 247, and the sealingsleeve 247 is used for sealing the joint of thevalve rod 242 and themovable channel 244 when thevalve rod 242 moves relative to themovable channel 244. That is, the provision of theseal sleeve 247 can improve the sealability of thevalve body assembly 240.

Based on the above structural arrangement, when thepull rod 261 is configured, thepull rod 261 may include arod body 263, afirst bending portion 264 and asecond bending portion 265; wherein, thefirst bending portion 264 is inserted into the bar-shapedhole 254 and slidably cooperates with the bar-shapedhole 254, thesecond bending portion 265 is connected with thevalve body assembly 240, and therod 263 slidably cooperates with theguide 262. In addition, in order to facilitate connection of thevalve rod 242 and thesecond bending portion 265, asecond mounting groove 243 connected to thesecond bending portion 265 of thepull rod 261 is formed at a portion of thevalve rod 242 located outside thevalve body 241. Thus, by such a structural arrangement, when the operatingwrench 250 rotates relative to themain body 210 under the action of external force, thefirst bending portion 264 slides relative to the strip-shapedhole 254, and under the limiting action of theguide 262, thepull rod 261 is guided to translate, so as to drive thesecond bending portion 265 connected with thevalve body assembly 240 to move, so that thevalve body assembly 240 conducts thewater pump assembly 220 with an external water pipe.

Thevalve body assembly 240 further includes areset member 248, thereset member 248 coupled to thevalve stem 242 and thevalve body 241, thereset member 248 configured to provide a tendency for thevalve stem 242 to move toward a position blocking thewater guide passage 245. Thus, when the external force applied to the operatingwrench 250 by the user is removed, thevalve rod 242 can move toward the position where thewater guide passage 245 is blocked by the restoringmember 248, that is, the restoringmember 248 can be restored by the restoringmember 248, and the restoringmember 248 in this embodiment is a spring disposed at the outer periphery of thevalve body 241.

In this embodiment, in order to limit the rotation state of the operatingwrench 250, themain body 210 is provided with a anti-self-locking button 270, the anti-self-locking button 270 is located at one side of the operatingwrench 250 facing away from theelectric control switch 230 and thevalve body assembly 240, and the anti-self-locking button 270 is used for limiting the rotation of the operatingwrench 250 relative to themain body 210. Thus, when the anti-self-locking button 270 is pressed, the restriction of the rotation of theoperation wrench 250 with respect to themain body 210 can be canceled, and at this time, theoperation wrench 250 can be rotated with respect to themain body 210 by the external force.

In summary, referring to fig. 1-9, thehandheld cleaning device 200 operates as follows:

when the user presses theoperation wrench 250 through the action of the finger, and further theoperation wrench 250 moves relative to themain body 210, the rotation of theoperation wrench 250 relative to themain body 210 triggers theelectric control switch 230 and thevalve body assembly 240, so that thewater pump assembly 220 is started and is communicated with the water path of the external water pipe;

wherein, the process of operating thewrench 250 to trigger theelectric control switch 230 includes: when theoperation wrench 250 rotates relative to themain body 210 under the action of external force, there is a relative motion between theoperation wrench 250 and thetrigger rod 232, and as theoperation wrench 250 continues to move along the same direction, the inner wall of the first mountinggroove 253 abuts against thetrigger rod 232 and drives thetrigger rod 232 to move, so as to trigger thetrigger rod 232 located in the first mountinggroove 253, and further, themotor 222 is electrified, and thepump body 221 is started, namely thewater pump assembly 220 is started;
