In the prior art, a manual switch is provided in the power supply circuit of the high-pressure pump 2 to manually cut off the power supply circuit of the high-pressure pump 2.

The locking member is arranged on the slide 6 and connected to the controller, wherein when the slide 32 is inserted into the slide 61 at a predetermined position (position where the sensing member 54 is triggered by the triggering member 55), the controller controls the locking member to lock the slide 32, and the controller disconnects the power supply circuit of the high-pressure pump 2 through the control circuit 52.

The card reader 51 is mounted on the mounting seat 42 and connected with the controller, wherein when the card reader 51 receives a card swiping signal, the controller controls the locking piece to unlock the sliding block 32, and meanwhile the controller conducts a power supply loop of the high-pressure pump 2 through the control circuit 52.

Specifically, the method comprises the following steps:

as shown in fig. 3, a vertically arranged push block 33 is fixedly installed at the bottom of the slide block 32;

as shown in fig. 5 and 6, an accommodating cavity 63 is formed at the inner bottom of the sliding seat 6; a channel 64 for communicating the groove bottom of the sliding groove 61 with the accommodating cavity 63 is formed in the upper wall of the accommodating cavity 63; wherein the push block 33 extends from the channel 64 into the receiving cavity 63 when the slide block 32 is inserted into the slide groove 61.

A movable block 7 capable of moving up/down is movably arranged in the accommodating cavity 63, wherein the movable block 7 can cover the lower port of the channel 64; the accommodating cavity 63 is also internally provided with an elastic piece 8 which enables the movable block 7 to keep the upward movement trend; the pushing block 33 is used for pushing the movable block 7 downwards, so that the movable block 7 moves downwards.

The sensing piece 54 is arranged on the side wall of the accommodating cavity 63; the triggering piece 55 is arranged on the side wall of the movable block 7 facing the sensing piece 54, wherein when the sliding block 32 is inserted into the sliding groove 61, the pushing block 33 at the bottom of the sliding block 32 penetrates through the channel 64 to push the movable block 7 continuously downwards until the bottom of the sliding block 32 contacts with the bottom wall of the sliding groove 61, at this time, the triggering piece 55 on the movable block 7 moves to the position of the sensing piece 54 along with the movable block 7 to trigger the sensing piece 54, and at this time, the lock tongue position of the electromagnetic lock 53 is located at the position of the insertion hole 322 of the sliding block 32.

When the sliding block 32 is pulled out of the sliding groove 61, the movable block 7 moves upwards under the elastic force of the elastic piece 8 until the movable block 7 abuts against the lower port of the channel 64, so that the lower port of the channel 64 is covered; in this way, dust is prevented from entering the accommodating chamber 63 from the passage 64 and affecting the sensing member 54.

In the present embodiment, the sensing element 54 is connected to the controller, and when the sensing element 54 is triggered by the triggering element 55, the controller controls the locking element to lock the slider 32, and at the same time, the controller disconnects the power supply circuit of the high-pressure pump 2 through the control circuit 52. So when slider 32 inserts the spout 61 tank bottom, ejector pad 33 promotes movable block 7 and moves to the response 54 position downwards, and response 54 is triggered by trigger 55 this moment, and then passes through control circuit 52 disconnection high-pressure pump 2's power supply loop through the controller, and simultaneously, the spring bolt of controller control electromagnetic lock 53 (locking piece) stretches out from perforating hole 62 and inserts in the jack 322 of slider 32 to play spacing locking effect to slider 32, make slider 32 unable upwards take out.

In this embodiment, the elastic member 8 includes a guide rod 81 vertically and fixedly installed in the accommodating cavity 63, and a spring 82 sleeved on the guide rod 81, wherein the movable block 7 is movably disposed on the guide rod 81, one end of the spring 82 abuts against the bottom wall of the accommodating cavity 63, and the other end abuts against the lower wall of the movable block 7. In this way, the guide rod 81 guides the movement of the movable block 7, and the spring 82 provides an elastic force to keep the movable block 7 always moving upward under the elastic force of the spring 82.

The implementation principle is as follows:

referring to fig. 5, when the spray gun 3 needs to be temporarily placed, the slide block 32 on the gun body 31 is inserted into the upper end of the slide groove 61 of the slide block 32, and in the process, the push block 33 below the slide block 32 continuously pushes the movable block 7 downwards through the channel 64 until the lower wall of the slide block 32 contacts with the lower wall of the slide groove 61, and the trigger 55 on the movable block 7 is located at the position of the sensing element 54 to trigger the sensing element 54; after the sensing element 54 is triggered, a trigger signal is sent to the controller; the controller controls the bolt of the electromagnetic lock 53 to extend and be inserted into the insertion hole 322 of the sliding block 32; at this time, the slide block 32 cannot be drawn out upwards under the limit of the bolt, so that the spray gun 3 is locked, and no person takes the spray gun 3. When the controller receives the trigger signal, the controller also controls the relay to act through the driving circuit, so that the relay disconnects the power supply loop of the high-pressure pump 2; thus, even if the worker forgets to turn off the power supply loop of the high-pressure pump 2, the relay can automatically turn off the power supply loop of the high-pressure pump 2; thereby preventing an irrelevant person from being electrically injured by the circuit of the high-pressure pump 2.

Referring to fig. 6, when the spray gun 3 needs to be taken again for use, a worker uses the IC card to read through the card reader 51, and when the card reader 51 senses a card reading signal, the card reading signal is sent to the controller, and the controller further controls the relay to operate through the driving circuit, so that the relay conducts the power supply loop of the high-pressure pump 2. When the controller receives the card swiping signal, the controller controls the bolt of the electromagnetic lock 53 to be recovered and drawn out from the jack 322 of the sliding block 32; therefore, the spray gun 3 can be freely drawn out from the chute 61 for use without the limit of the bolt of the electromagnetic lock 53.

When the spray gun 3 is drawn out, the movable block 7 is not pushed by the pushing block 33, and under the elastic force of the spring 82, the movable block 7 is displaced upwards until the movable block 7 abuts against the lower port of the channel 64, as shown in fig. 6, so as to cover the lower port of the channel 64, thereby preventing dust from entering the accommodating cavity 63 from the channel 64 and influencing the later use of the sensing piece 54.

The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the present invention.
