Abstract
Description
Technical Field
[0001] This invention relates to the field of sprayers, and in particular to a sprayer with a bottle washing function. Background Technology
[0002] A sprayer is short for spraying equipment. It's a device that uses air suction to turn pesticides or other liquids into a mist, which is then sprayed evenly onto other objects. It consists of a compressed air unit, a thin tube, and nozzles. In rural areas, sprayers are indispensable agricultural tools for controlling pests and diseases. When using a sprayer, the pesticide is placed inside the casing, and then water is added to dissolve the pesticide.
[0003] Utility model patent CN221749463U discloses a sprayer for cleaning medicine bottles, including a sprayer body. The upper end of the sprayer body is provided with a water inlet and a medicine inlet. The bottom end of the sprayer body is provided with an installation space. A bottom mounting plate is installed at the bottom of the installation space. A battery and a water pump are installed on the bottom mounting plate. The output end of the water pump is connected to a three-way regulating valve. One end of the three-way regulating valve is connected to a flushing pipe.
[0004] The aforementioned technical solutions have the following drawbacks: after the valve of the flushing pipeline is opened, water will spray directly upward from the water outlet of the puncture part. If someone accidentally opens this valve and there is no bottle on the puncture part, the sprayed water will most likely splash onto their face or body, getting them wet. Summary of the Invention
[0005] To address the issue of water spraying directly and potentially wetting people when the flushing pipe is accidentally opened, this application provides a sprayer with a bottle-washing function.
[0006] The sprayer with bottle-washing function provided in this application adopts the following technical solution:
[0007] A sprayer with a bottle washing function includes a sprayer body, a puncture head, a support frame, a fixing block, several trigger drive components and several sealing rods. The upper end of the sprayer body is provided with a water inlet and a medicine inlet. The bottom end of the sprayer body is provided with a base. The base is provided with a storage battery and a pump body. The output end of the pump body is provided with a three-way regulating valve. One end of the three-way regulating valve is connected to a flushing pipeline.
[0008] The inner wall of the dosing port is provided with a support assembly for supporting the support frame. The support frame has a coaxial mounting hole, and the puncture head is fixedly mounted on the mounting hole. A flushing channel is provided inside the puncture head. The fixing block is fixedly mounted below the puncture head and the support frame. The fixing block has a connecting channel that connects the flushing pipe and the flushing channel.
[0009] The sealing rod is slidably disposed within the fixed block along the radial direction of the support frame. Several sealing rods are distributed circumferentially, and several triggering drive elements correspond one-to-one with several sealing rods. The sealing rod is used to block the flushing channel. The triggering drive element is used to drive the corresponding sealing rod to move away from the flushing channel when most of the puncture head has entered the bottle, and to drive the corresponding sealing rod to move to the ends of several sealing rods to abut against each other when the puncture head has not entered the bottle, so as to block the flushing channel together.
[0010] By adopting the above technical solution, the condition of the medicine bottle and the puncture head is judged by the triggering drive component, and the sealing rod is moved to control the opening and closing of the flushing channel, thereby improving the situation where the flushing pipeline may spray water directly and wet people if the water is accidentally turned on.
[0011] Preferably, the trigger drive includes a support rod, a first spring, a gear, and a first rod. The gear is rotatably connected to the fixed block and located below the corresponding blocking rod. The first rod slides parallel to the sliding direction of the corresponding blocking rod within the fixed block. The blocking rod and the first rod are located on opposite sides of the gear. The blocking rod and the first rod have toothed surfaces on their sides facing the gear. The gear meshes with the two toothed surfaces of the blocking rod and the first rod.
[0012] One end of the first rod extends out of the fixing block and is fixed to the bottom end of the corresponding support rod. The support frame has several sliding grooves along the circumferential direction. Several support rods slide in the several sliding grooves respectively. Several support rods surround the outside of the piercing head along the circumferential direction. The top of the piercing head is located above the several support rods. The first spring is set in the sliding groove and is used to drive the support rod to move away from the piercing head. The support rod is bent away from the piercing head. The bent part of the support rod is used to abut against the inner wall of the bottle mouth.
[0013] By adopting the above technical solution, when pesticides need to be added, the operator inserts the piercing head into the bottle with the opening facing down. If there is a sealing film at the opening, the piercing head will pierce the film, allowing the pesticide to flow out. At the same time, the bottle opening will abut against the support rod, driving the support rod to move inward along its bent, inclined upper end. Finally, the bottle opening will abut against the top surface of the support frame. Under the action of the first spring, the support rod will always be pressed against the inner wall of the bottle opening. The support rod can limit the position of the bottle, allowing it to stand upright without external force. The operator does not need to hold the bottle with their hands throughout the entire washing process, freeing their hands. At the same time, the bottle drives the movement of the support rod, which determines whether the bottle needs to be cleaned. The movement of the support rod drives the gear to rotate, thereby moving the sealing rod to open the flushing channel. The support rod also guides the water flow, reducing the chance of water getting stuck at the bottle opening.
[0014] Preferably, the support assembly includes a fixed support ring, an elastic element, and several movable blocks. The fixed support ring is coaxially fixedly mounted on the inner wall of the dosing port. A first annular groove is formed on the inner wall of the fixed support ring in the circumferential direction. A wavy toothed groove is formed on the inner wall of the first annular groove in the circumferential direction. A transition groove is also formed on the upwardly protruding toothed end of the wavy toothed groove along the axial direction of the fixed support ring. Several movable blocks are evenly arranged on the support frame in the circumferential direction. The movable blocks slide in the wavy toothed groove and the transition groove. The elastic element is used to drive the support frame to move upward. Under the action of the elastic element alone, the movable blocks are always located in the corresponding transition grooves. The top end of the flushing pipeline is rotatably connected to the fixed block.
[0015] By adopting the above technical solution, since the support rod abuts against the inner wall of the bottle mouth, the contact point between the support rod and the inner wall of the bottle mouth may result in high concentrations of pesticide residue that are not diluted by water rinsing. Discarding the bottle will pollute the environment. Therefore, to address this issue, the operator presses the bottle to move the support frame downwards. The movable block can then move diagonally downwards along the wavy toothed groove, thereby rotating the support frame. After releasing the force, the movable block, under the action of the elastic element, moves diagonally upwards along the wavy toothed groove into the transition groove. Throughout the process, the rotation of the support frame causes the support rod to rotate as well, thus changing the contact position between the support rod and the inner wall of the bottle mouth, thereby better diluting the undiluted pesticide. Compared to the operator directly rotating the bottle, which makes it difficult to control the direction of force and may cause the bottle to detach from the piercing head due to operational errors, requiring the bottle to be repositioned, this direct pressing method provides a much more stable direction of force, reducing the likelihood of the bottle detaching from the piercing head. At the same time, after the support rod rotates, it can better guide the water flow out of the bottle mouth.
[0016] Preferably, a second annular groove is formed on the top wall of the first annular groove along the circumferential direction, and a plurality of elastic elements are distributed in the second annular groove along the circumferential direction. The elastic elements include a first block, a second block, and a second spring. The second block is fixedly disposed on the top surface of the support frame. The first block is slidably disposed at 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 fixedly disposed on the first block and the second block, respectively. The second spring is always in a stretched state.
[0017] 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 force to exert an upward force on the support frame.
[0018] Preferably, it also includes a drive component one, which is used to drive several support rods to tighten inward to the limit position when the movable block moves to the bottom of the wavy toothed groove. When the movable block moves into the transition groove, the drive component one does not act on the support rods.
[0019] Preferably, the driving component includes a plurality of abutment rods, each abutment rod being fixed to a plurality of support rods in a corresponding manner. The abutment rods are located below the support frame, with one end of the abutment rod away from the support frame extending into the first annular groove and having an inclined surface facing downwards. The inclined surface is used to abut against the corner of the first annular groove of the support frame.
[0020] By adopting the above technical solution, when the support frame moves down, the inclined surface on the abutment can abut against the corner of the first annular groove of the support frame. The abutment 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 mouth of the medicine bottle and the support rod, reducing the chance of high concentration pesticide residues.
[0021] Preferably, the bend of the support rod is covered with an anti-slip pad.
[0022] By adopting the above technical solution, the anti-slip pad can better fit the inner wall of the medicine bottle opening, increase the contact area with the inner wall of the bottle opening, and improve the stability of the medicine bottle after it is limited by the support rod.
[0023] The main technical effects of this invention are reflected in the following aspects:
[0024] 1. This invention uses a trigger drive to determine the condition of the medicine bottle and the puncture head, thereby driving the sealing rod to move and controlling the opening and closing of the flushing channel, thus improving the situation where the flushing pipeline might accidentally spray water directly and wet people.
[0025] 2. This invention incorporates a support rod that limits the position of the medicine bottle, allowing it to stand upright without external force. This eliminates the need for operators to hold the bottle throughout the washing process, freeing their hands. Simultaneously, the bottle drives the support rod's movement, which determines whether cleaning is required. The rod's movement also rotates gears, causing the sealing rod to move and open the rinsing channel. Furthermore, the support rod guides the water flow, reducing the likelihood of water clogging the bottle opening. Attached Figure Description

[0033] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.
[0034] This application discloses a sprayer with a bottle washing function.
[0035] Reference Figures 1-4 This embodiment of a sprayer with a bottle-washing function includes a sprayer housing 1, a puncture head 4, a support frame 3, a fixing block 5, several trigger drive components 7, and several sealing rods 6. The upper end of the sprayer housing 1 is provided with a water inlet 11 and a medicine inlet 12, each threadedly connected to a cap 13. The bottom end of the sprayer housing 1 has a base 14, which houses a battery and a pump 15. The output end of the pump 15 is equipped with a three-way regulating valve. One end of the three-way regulating valve is connected to a flushing pipe 10, and the other two ends are connected to a water spray pipe 17 and a stirring pipe, respectively. The stirring pipe is directly connected to the interior of the sprayer housing 1, and the water spray pipe 17 is connected to a handheld nozzle 18. The base 14 is equipped with three switches 16, which control the opening and closing of the three pipes of the three-way regulating valve. The back of the sprayer housing 1 is provided with shoulder straps 19 for the operator to carry.
[0036] Reference Figures 1-4A support assembly 2 is provided on the inner wall of the dosing port 12 to support the support frame 3. The axis of the support frame 3 is vertically arranged. A mounting hole 31 is coaxially opened on the support frame 3. The puncture head 4 is fixedly installed on the mounting hole 31. A flushing channel 41 is opened inside the puncture head 4. A fixing block 5 is fixedly installed below the puncture head 4 and the support frame 3. A connecting channel 51 connecting the flushing pipe 10 and the flushing channel 41 is opened on the fixing block 5.
[0037] Reference Figure 2 , Figure 4 and Figure 5 The sealing rod 6 is slidably disposed in the fixed block 5 along the radial direction of the support frame 3. Several sealing rods 6 are distributed circumferentially. Several triggering drive elements 7 correspond one-to-one with several sealing rods 6. The sealing rod 6 is used to block the flushing channel 41. When most of the puncture head 4 has entered the bottle, the triggering drive element 7 is used to drive the corresponding sealing rod 6 to move away from the flushing channel 41. When the puncture head 4 has not entered the bottle, the corresponding sealing rod 6 is driven to move to the ends of several sealing rods 6 to abut against each other and jointly block the flushing channel 41.
[0038] Reference Figure 2 , Figure 4 and Figure 5 The system determines the condition of the medicine bottle and the puncture head 4 by triggering the drive component 7, and then drives the sealing rod 6 to move to control the opening and closing of the flushing channel 41, thereby improving the situation where the flushing pipeline 10 is accidentally turned on and water sprays out directly, which could easily wet people.
[0039] Reference Figure 2 , Figure 4 and Figure 5 The trigger drive component 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 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 located on both sides of the gear 73. The blocking rod 6 and the first rod 74 have toothed surfaces on one side facing the gear 73. The gear 73 meshes with the two toothed surfaces of the blocking rod 6 and the first rod 74.
[0040] Reference Figure 2 , Figure 4 and Figure 5 One end of the first rod 74 extends out of the fixing block 5 and is fixed to the bottom end of the corresponding support rod 71. Several grooves 32 are provided on the support frame 3 along the circumferential direction. Several support rods 71 slide in the grooves 32 respectively. Several support rods 71 surround the outside of the piercing head 4 along the circumferential direction. The top of the piercing head 4 is located above the support rods 71. The first spring 72 is set in the groove 32 and is used to drive the support rods 71 to move away from the piercing head 4. The support rods 71 are bent away from the piercing head 4. The bent part of the support rods 71 is used to abut against the inner wall of the bottle mouth.
[0041] Reference Figure 2 , Figure 4 and Figure 5 When pesticides need to be added, the operator inserts the piercing head 4 into the bottle with the opening facing down. If there is a seal at the opening, the piercing head 4 will pierce the seal, allowing the pesticide to flow out. At the same time, the bottle opening will abut against the support rod 71, driving the support rod 71 to move inward along its bent, inclined upper end. Finally, the bottle opening will abut against the top surface of the support frame 3. Under the action of the first spring 72, the support rod 71 will always be pressed against the inner wall of the bottle opening. The support rod 71 can limit the position of the pesticide bottle, allowing it to move freely. The bottle stands upright without external force, eliminating the need for operators to hold the bottle throughout the washing process and freeing their hands. Simultaneously, the bottle drives the movement of the support rod 71, which determines whether the bottle needs cleaning. The movement of the support rod 71 drives the gear 73 to rotate, thereby moving the sealing rod 6 to open the rinsing channel 41. At the same time, the support rod 71 can guide the water flow, reducing the chance of water getting stuck at the bottle opening.
[0042] Reference Figure 2 , Figure 4 and Figure 5 The support assembly 2 includes a fixed support ring 21, an elastic element 22, and several movable blocks 23. The fixed support ring 21 is coaxially fixed on the inner wall of the dosing port 12. The inner wall of the fixed support ring 21 has a first annular groove 211 along the circumferential direction. The inner wall of the first annular groove 211 has a wavy toothed groove 212 along the circumferential direction. The toothed end of the wavy toothed groove 212 also has a transition groove 213 along the axial direction of the fixed support ring 21. Several movable blocks 23 are evenly arranged on the support frame 3 along the circumferential direction. The movable blocks 23 slide in the wavy toothed groove 212 and the transition groove 213. The elastic element 22 is used to drive the support frame 3 to move upward. Under the action of the elastic element 22 alone, the movable blocks 23 are always located in the corresponding transition groove 213. The top end of the flushing pipe 10 is rotatably connected to the fixed block 5.
[0043] Reference Figure 2 , Figure 4 and Figure 5Because the support rod 71 abuts against the inner wall of the medicine bottle opening, a high concentration of pesticide residue may remain undiluted by rinsing with water at the point of contact between the support rod 71 and the inner wall of the medicine bottle opening. Discarding the medicine bottle would pollute the environment. Therefore, to address this issue, the operator presses the medicine bottle to move the support frame 3 downwards. The movable block 23 then moves diagonally downwards along the wavy toothed groove 212, causing the support frame 3 to rotate. After releasing the force, the movable block 23, under the action of the elastic element 22, moves diagonally upwards along the wavy toothed groove 212 and enters the transition groove 213. The entire process... In the process, the rotation of the support frame 3 causes the support rod 71 to rotate as well, thus changing the contact position between the support rod 71 and the inner wall of the bottle opening, thereby better diluting the undiluted pesticide. Compared to the operator directly rotating the bottle, which makes it difficult to control the direction of force and may cause the bottle to detach from the piercing head 4 due to operational errors, requiring the bottle to be repositioned, the direct pressing method provides a much more stable direction of force, making it less likely for the bottle to detach from the piercing head 4. At the same time, after the support rod 71 rotates, it can better guide the water flow out of the bottle opening.
[0044] Reference Figure 2 , Figures 4-6 A second annular groove 214 is provided on the top wall of the first annular groove 211 along the circumferential direction. A number of elastic elements 22 are distributed in the second annular groove 214 along the circumferential direction. The elastic element 22 includes a first block 221, a second block 222, and a second spring 223. The second block 222 is fixedly installed on the top surface of the support frame 3. The first block 221 is slidably installed at the top of the second annular groove 214 along the circumferential direction. The two ends of the second spring 223 are fixedly installed on the first block 221 and the second block 222, respectively. The second spring 223 is always in a stretched state.
[0045] 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 force to the support frame 3 to exert an upward force.
[0046] Reference Figure 2 , Figure 4 and Figure 5 It also includes a drive component 8, which drives several support rods 71 to tighten inward to their limit position when the movable block 23 moves to the bottom of the wave toothed groove 212. When the movable block 23 moves into the transition groove 213, the drive component 8 does not act on the support rods 71.
[0047] Reference Figure 2 , Figure 4 and Figure 5The driving component 8 includes several abutment rods 81, which are fixed one-to-one on several support rods 71. The abutment rods 81 are located below the support frame 3. The end of the abutment rod 81 away from the support frame 3 extends into the first annular groove 211 and has an inclined surface 811 facing downward. The inclined surface 811 is used to abut against the corner of the first annular groove 211 of the support frame 3.
[0048] Reference Figure 2 , Figure 4 and Figure 5 When the support frame 3 moves down, the inclined surface 811 on the abutment rod 81 can abut against the corner of the first annular groove 211 of the support frame 3. The abutment 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 mouth of the medicine bottle and the support rod 71, reducing the chance of high concentration pesticide residue.
[0049] Reference Figure 2 , Figure 4 and Figure 5 The bend of the support rod 71 is covered with an anti-slip pad. The anti-slip pad can better conform to the inner wall of the bottle mouth, increase the contact area with the inner wall of the bottle mouth, and improve the stability of the bottle after it is limited by the support rod 71.
[0050] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
