[0004] The above-mentioned related technical solutions have the following defects: after opening the valve of the flushing pipeline, water will spray upward directly from the water outlet of the piercing member. If someone opens the valve by mistake and there is no bottle on the piercing member, the sprayed water will most likely splash onto the face or body, getting the person wet. Summary of the invention

[0005] In order to improve the problem that water may directly spray out and easily wet people when the flushing pipeline is opened by mistake, the present application provides a sprayer with a bottle washing function.

[0006] The present application provides a sprayer with a bottle washing function using the following technical solution: A sprayer with a bottle washing function, comprising a sprayer housing, a piercing head, a support frame, a fixing block, a plurality of trigger driving members and a plurality of blocking rods, wherein the upper end of the sprayer housing is respectively provided with a water inlet and a medicine inlet, and the bottom end of the sprayer housing is provided with a base, wherein a battery and a pump body are arranged in the base, and a three-way regulating valve is arranged at the output end of the pump body, and one end of the three-way regulating valve is connected with a flushing pipeline; A support assembly is provided on the inner wall of the drug adding port for supporting a support frame, a mounting hole is coaxially provided on the support frame, the puncture head is fixedly arranged on the mounting hole, and a flushing channel is provided in the puncture head; the fixing block is fixedly arranged below the puncture head and the support frame, and a connecting channel connecting the flushing pipeline and the flushing channel is provided on the fixing block; The blocking rod is slidably arranged in the fixed block along the radial direction of the support frame, and a plurality of blocking rods are distributed along the circumferential direction. A plurality of trigger driving members correspond to the plurality of blocking rods one by one. The blocking rod is used to block the flushing channel. The trigger driving member is used to drive the corresponding blocking rod to move away from the flushing channel when most of the puncture head enters the bottle, and to drive the corresponding blocking rod to move until the ends of the plurality of blocking rods abut against each other to jointly block the flushing channel when the puncture head does not enter the bottle.

[0007] By adopting the above technical solution, the driving member is triggered to determine the situation of the medicine bottle and the puncture head, so as to drive the blocking rod to move, thereby controlling the opening and closing of the flushing channel, thereby improving the situation in which the flushing pipeline is opened by mistake and water is sprayed out directly, which may easily wet people.

[0008] Preferably, the trigger driving member comprises a support rod, a first spring, a gear and a first rod, the gear is rotatably connected in the fixed block and is located below the corresponding blocking rod, the first rod slides in the fixed block parallel to the sliding direction of the corresponding blocking rod, the blocking rod and the first rod are respectively located on both sides of the gear, the blocking rod and the first rod are provided with tooth surfaces on one side facing the gear, and the gear is meshedly connected to the two tooth surfaces of the blocking rod and the first rod; One end of the first rod extends out of the fixed block and is fixed to the bottom end of the corresponding support rod. A plurality of slide grooves are opened on the support frame along the circumferential direction. A plurality of support rods slide in the plurality of slide grooves respectively. A plurality of support rods surround the outside of the puncture head along the circumferential direction. The top of the puncture head is located above the plurality of support rods. The first spring is arranged in the slide groove to drive the support rod to move toward the side away from the puncture head. The support rod is bent toward the side away from the puncture head, and the bent part of the support rod is used to abut against the inner wall of the bottle mouth.

[0009] By adopting the above technical solution, when it is necessary to add pesticides, the operator will insert the medicine bottle mouth downwards towards the puncturing head. If there is a sealing film at the medicine mouth, the puncturing head will puncture the sealing film to make the medicine in the bottle flow out, and at the same time, the medicine bottle mouth will abut on the support rod, and the support rod will be driven to move inward along the inclined upper end after the support rod is bent, and finally the medicine bottle mouth abuts on the top surface of the support frame. Under the action of the first spring, the support rod always presses against the inner wall of the bottle mouth, and the support rod can limit the medicine bottle, so that the medicine bottle can stand up without external force. The operator does not need to hold the medicine bottle with his hand during the entire bottle washing process, freeing the operator's hands; at the same time, the medicine bottle drives the movement of the support rod, and the movement of the support rod is used to determine whether the medicine bottle needs to be cleaned. The movement of the support rod drives the gear to rotate, thereby driving the blocking rod to move away from the flushing channel to open the flushing channel; at the same time, the support rod can guide the water flow, reducing the probability of water flow being blocked at the mouth of the medicine bottle and unable to come out.

[0010] Preferably, the support assembly includes a fixed support ring, an elastic member and a plurality of movable blocks, the fixed support ring is coaxially fixed on the inner wall of the dosing port, the inner wall of the fixed support ring is provided with a first annular groove along the circumferential direction, the inner wall of the first annular groove is provided with a wavy tooth-shaped groove along the circumferential direction, and the tooth end of the wavy tooth-shaped groove protruding upward is also provided with a transition groove along the axial direction of the fixed support ring, a plurality of movable blocks are evenly arranged on the support frame along the circumferential direction, the movable blocks slide in the wavy tooth-shaped groove and the transition groove, the elastic member is used to drive the support frame to move upward, and the movable block is always located in the corresponding transition groove only under the action of the elastic member; the top end of the flushing pipeline is rotatably connected to the fixed block.

[0011] By adopting the above technical solution, since the support rod abuts against the inner wall of the mouth of the medicine bottle, the abutment between the support rod and the inner wall of the mouth of the medicine bottle will cause high-concentration pesticide residues that are not diluted by water washing, and the medicine bottle will cause pollution to the environment after being discarded. Therefore, in view of the above situation, the operator drives the support frame downward by pressing the medicine bottle, and the movable block can move obliquely downward along the wave-toothed groove, thereby driving the support frame to rotate. After giving up the force, the movable block moves obliquely upward along the wave-toothed groove under the action of the elastic member and enters the transition groove. During the whole process, the rotation of the support frame drives the support rod to rotate together, so the support rod will change the contact position with the inner wall of the mouth of the medicine bottle, thereby better diluting the undiluted pesticide; compared with the operator directly rotating the medicine bottle, it is impossible to control the direction of force well, and it is very likely that the medicine bottle will be separated from the puncture head due to an operating error, and the medicine bottle will have to be re-placed, which is more troublesome. Therefore, after adopting the direct pressing method, the direction of force is much more stable, and it is difficult for the medicine bottle to be separated from the puncture head; at the same time, after the support rod is rotated, the support rod can better guide the water to flow out of the bottle mouth.

[0012] Preferably, a second annular groove is circumferentially provided on the top wall of the first annular groove, and a plurality of elastic members are circumferentially distributed in the second annular groove, the elastic members include a first block, a second block and a second spring, the second block is fixedly arranged on the top surface of the support frame, the first block is slidably arranged on the top end of the second annular groove along the circumferential direction of the second annular groove, the two ends of the second spring are respectively fixedly arranged on the first block and the second block, and the second spring is always in a stretched state.

[0013] By adopting the above technical solution, when the support frame rotates, it can drive the second block to rotate synchronously in the second annular groove, and the second spring can always apply an upward force to the support frame.

[0014] Preferably, it also includes a driving member 1, which is used to drive a plurality of support rods to be tightened inward to the extreme position when the movable block moves to the bottom end of the wave-toothed groove. When the movable block moves into the transition groove, the driving member 1 does not act on the support rods.

[0015] Preferably, the driving member comprises a plurality of push rods, which are respectively fixed on a plurality of support rods, and the push rods are located below the support frame. One end of the push rod away from the support frame extends into the first annular groove and is provided with an inclined surface inclined downward, and the inclined surface is used to abut against the edge corner of the first annular groove of the support frame.

[0016] By adopting the above technical solution, when the support frame moves downward, the inclined surface on the support rod can abut against the edge of the first ring groove of the support frame, and the support rod will move inward toward the axis of the support frame, thereby driving the support rod to move inward synchronously, so that the support rod is separated from the inner wall of the medicine bottle. At this time, the water flow can more completely rinse the bottle mouth and the support rod, reducing the chance of high-concentration pesticide residues.

[0017] Preferably, the bending part of the support rod is covered with an anti-slip pad.

[0018] By adopting the above technical solution, the anti-slip pad can better fit the inner wall of the mouth of the medicine bottle, increase the contact area with the inner wall of the bottle mouth, and improve the stability of the medicine bottle after being limited by the support rod.

[0019] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention determines the situation of the medicine bottle and the puncture head by triggering the driving member to drive the blocking rod to move, thereby controlling the opening and closing of the flushing channel, thereby improving the situation where the flushing pipeline is easily wetted by water spraying directly when it is opened by mistake; 2. The present invention provides a support rod, which can limit the medicine bottle so that the medicine bottle can stand up without external force. The operator does not need to hold the medicine bottle with his hands during the entire bottle washing process, thus freeing the operator's hands. At the same time, the medicine bottle drives the movement of the support rod, and the movement of the support rod is used to determine whether the medicine bottle needs to be cleaned. The movement of the support rod drives the gear to rotate, thereby driving the blocking rod to move away from the flushing channel to open the flushing channel. At the same time, the support rod can guide the water flow, reducing the probability of water being blocked at the mouth of the medicine bottle and unable to come out.

A flushing channel 41 is provided in the puncture head 4. A fixed block 5 is fixedly arranged below the puncture head 4 and the support frame 3. A connecting channel 51 connecting the flushing pipeline 10 and the flushing channel 41 is provided on the fixed block 5.

[0031] Reference Figure 2 , Figure 4 and Figure 5 The blocking rod 6 is slidably arranged in the fixed block 5 along the radial direction of the support frame 3, and a plurality of blocking rods 6 are distributed along the circumferential direction. A plurality of trigger driving members 7 correspond one to one to the plurality of blocking rods 6. The blocking rod 6 is used to block the flushing channel 41. The trigger driving member 7 is used to drive the corresponding blocking rod 6 to move away from the flushing channel 41 when most of the puncture head 4 enters the bottle, and to drive the corresponding blocking rod 6 to move to the end portions of the plurality of blocking rods 6 to abut against each other to jointly block the flushing channel 41 when the puncture head 4 has not entered the bottle.

[0032] Reference Figure 2 , Figure 4 and Figure 5 By triggering the driving member 7 to judge the situation of the medicine bottle and the puncture head 4, the blocking rod 6 is driven to move to control the opening and closing of the flushing channel 41, thereby improving the situation where the flushing pipeline 10 is opened by mistake and water is directly sprayed out, which is easy to wet people.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The trigger driving member 7 includes a support rod 71, a first spring 72, a gear 73 and a first rod 74. The gear 73 is rotatably connected in the fixed block 5 and is located below the corresponding blocking rod 6. The first rod 74 slides in the fixed block 5 parallel to the sliding direction of the corresponding blocking rod 6. The blocking rod 6 and the first rod 74 are respectively located on both sides of the gear 73. The blocking rod 6 and the first rod 74 are provided with tooth surfaces on one side of the gear 73, and the gear 73 is meshed and connected to the two tooth surfaces of the blocking rod 6 and the first rod 74.

[0034] Reference Figure 2 , Figure 4 and Figure 5 One end of the first rod 74 extends out of the fixed block 5 and is fixed to the bottom end of the corresponding support rod 71. A plurality of slide grooves 32 are opened on the support frame 3 along the circumferential direction. A plurality of support rods 71 ​​slide in the plurality of slide grooves 32 respectively. A plurality of support rods 71 ​​surround the outside of the puncture head 4 along the circumferential direction. The top of the puncture head 4 is located above the plurality of support rods 71. A first spring 72 is arranged in the slide groove 32 to drive the support rod 71 to move toward the side away from the puncture head 4. The support rod 71 is bent toward the side away from the puncture head 4, and the bent portion of the support rod 71 is used to abut against the inner wall of the bottle mouth.

[0035] Reference Figure 2 , Figure 4 and Figure 5 When it is necessary to add pesticides, the operator will insert the piercing head 4 with the mouth of the medicine bottle facing downward. If there is a sealing film at the mouth of the medicine, the piercing head 4 will pierce the sealing film to make the medicine in the bottle flow out. At the same time, the mouth of the medicine bottle will abut on the support rod 71, and the support rod 71 will be driven to move inward along the inclined upper end after the support rod 71 is bent. Finally, the mouth of the medicine bottle abuts on the top surface of the support frame 3. The support rod 71 is always pressed against the inner wall of the bottle mouth under the action of the first spring 72. The support rod 71 can limit the position of the medicine bottle, so that the medicine bottle can It stands up without the action of external force, and the operator does not need to hold the medicine bottle with hands during the entire bottle washing process, thus freeing the operator's hands; at the same time, the medicine bottle drives the movement of the support rod 71, and the movement of the support rod 71 is used to determine whether the medicine bottle needs to be cleaned. The movement of the support rod 71 drives the gear 73 to rotate, thereby driving the blocking rod 6 to move away from the flushing channel 41, thereby opening the flushing channel 41; at the same time, the support rod 71 can guide the water flow, thereby reducing the probability of water flow being blocked at the mouth of the medicine bottle and unable to come out.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The support assembly 2 includes a fixed support ring 21, an elastic member 22 and a plurality of movable blocks 23. The fixed support ring 21 is coaxially fixedly arranged on the inner wall of the dosing port 12. A first annular groove 211 is provided on the inner wall of the fixed support ring 21 along the circumferential direction. A wavy tooth-shaped groove 212 is provided on the inner wall of the first annular groove 211 along the circumferential direction. A transition groove 213 is also provided on the tooth end protruding upward of the wavy tooth-shaped groove 212 along the axial direction of the fixed support ring 21. A plurality of movable blocks 23 are evenly arranged on the support frame 3 along the circumferential direction. The movable blocks 23 slide in the wavy tooth-shaped groove 212 and the transition groove 213. The elastic member 22 is used to drive the support frame 3 to move upward. Only under the action of the elastic member 22, the movable block 23 is always located in the corresponding transition groove 213; the top end of the flushing pipeline 10 is rotatably connected to the fixed block 5.

[0037] Reference Figure 2 , Figure 4 and Figure 5Since the support rod 71 abuts against the inner wall of the bottle mouth of the medicine bottle, the abutment between the support rod 71 and the inner wall of the bottle mouth of the medicine bottle will cause high-concentration pesticide residues that are not diluted by water washing, and the medicine bottle will cause environmental pollution after being discarded. Therefore, in view of the above situation, the operator presses the medicine bottle to drive the support frame 3 to move downward, and the movable block 23 can move obliquely downward along the wavy toothed groove 212, thereby driving the support frame 3 to rotate. After giving up the force, the movable block 23 moves obliquely upward along the wavy toothed groove 212 under the action of the elastic member 22 and enters the transition groove 213. The whole process In the process, the support frame 3 rotates and drives the support rod 71 to rotate together, so the support rod 71 will change the contact position with the inner wall of the bottle mouth, so as to better dilute the undiluted pesticide; compared with the operator directly rotating the medicine bottle, it is impossible to control the direction of force well, and it is very likely that the medicine bottle will be separated from the puncture head 4 due to operating errors, and the medicine bottle will have to be replaced, which is more troublesome. Therefore, after adopting the direct pressing method, the direction of force is much more stable, and it is difficult for the medicine bottle to be separated from the puncture head 4; at the same time, after the support rod 71 rotates, the support rod 71 can better guide the water to flow out of the bottle mouth.

The second block 222 is fixedly arranged on the top surface of the support frame 3, and the first block 221 is slidably arranged on the top end of the second annular groove 214 along the circumferential direction of the second annular groove 214. The two ends of the second spring 223 are fixedly arranged on the first block 221 and the second block 222, respectively, and the second spring 223 is always in a stretched state.

[0039] Reference Figure 5 and Figure 6 When the support frame 3 rotates, it can drive the second block 222 to rotate synchronously in the second annular groove 214 , and the second spring 223 can always apply an upward force to the support frame 3 .

[0040] Reference Figure 2 , Figure 4 and Figure 5 , and also includes a driving member 8, which is used to drive a plurality of support rods 71 ​​to tighten inward to the extreme position when the movable block 23 moves to the bottom end of the wave-toothed groove 212. When the movable block 23 moves into the transition groove 213, the driving member 8 does not act on the support rod 71.

[0041] Reference Figure 2 , Figure 4 and Figure 5The driving member 8 includes a plurality of push rods 81, which are fixed one by one on a plurality of support rods 71. The push rods 81 are located below the support frame 3. One end of the push rod 81 away from the support frame 3 extends into the first annular groove 211 and is provided with an inclined surface 811 inclined downward. The inclined surface 811 is used to abut against the corner of the first annular groove 211 of the support frame 3.

[0042] Reference Figure 2 , Figure 4 and Figure 5 When the support frame 3 moves downward, the inclined surface 811 on the support rod 81 can abut against the corner of the first annular groove 211 of the support frame 3, and the support rod 81 will move inward toward the axis of the support frame 3, thereby driving the support rod 71 to move inward synchronously, so that the support rod 71 is separated from the inner wall of the medicine bottle. At this time, the water flow can more completely rinse the bottle mouth and the support rod 71, reducing the probability of high-concentration pesticide residues.
