Description

Technical Field

[0001] The invention relates to the technical field of electric sprayers, in particular to an electric sprayer with a nozzle self-cleaning and anti-clogging function. Background Art

[0002] The electric sprayer is composed of a liquid storage barrel connected in sequence through a filter, a connecting head, a suction device, a connecting pipe, a nozzle, and a nozzle. The suction device is a small electric pump, which is electrically connected to the battery through wires and switches. The battery box is installed at the bottom of the liquid storage barrel. The liquid storage barrel can be made into a groove with a sunken battery. The advantage of the electric sprayer is that it eliminates the suction suction cylinder, thereby effectively eliminating the disadvantage of pesticide external filtration that harms the operator, and it saves effort. The pressure of the electric pump is greater than that of the manual suction cylinder, which increases the spraying distance and range, has a good atomization effect, saves time, effort, and medicine, and is widely used in general industrial equipment, medical equipment, chemical equipment, agriculture (lawns and gardens), tourist vehicles, special vehicles, ships, beverages, vehicle cleaning, carpet cleaning, floor cleaning, water purification and water treatment equipment.

[0003] When the existing electric sprayer is spraying, since it does not have an automatic cleaning function, foreign particles in the liquid will enter the nozzle along with the flow of the liquid, causing the foreign particles to block the nozzle, thereby affecting the service life of the nozzle. Summary of the invention

[0004] The object of the present invention is to provide an electric sprayer with a nozzle self-cleaning and anti-clogging function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: the electric sprayer with nozzle self-cleaning and anti-clogging function comprises a base, a support rod is installed on the base, a liquid storage tank is installed on the support rod, a suction pump and a nozzle body are installed at the bottom of the liquid storage tank, the input end of the suction pump is connected to the liquid storage tank through a suction pipe, and the output end of the suction pump is connected to the lower part of the nozzle body through a liquid infusion pipe, a tube body is rotatably installed on both sides of the nozzle body, an atomizing nozzle is installed at the end of the tube body, a filter is installed in the nozzle body, and two module guide rails are symmetrically installed on the inner upper part of the nozzle body, and two module guide rails are slidably installed on the two module guide rails. There is a slide seat, a connecting rod is installed at the bottom of the slide seat, and a cleaning plate is installed on the connecting rod. The cleaning plate is in contact with the upper surface of the filter screen. When spraying is required, the suction pump is started, and the liquid in the liquid storage tank can be transported to the nozzle body through the suction tube and the infusion tube. The liquid entering the tube body can be filtered through the filter screen, which can ensure that the atomizing nozzle can continuously and efficiently spray the liquid. At the same time, starting the module guide rail can allow the slide seat to drive the cleaning plate to move back and forth through the connecting rod, so that the cleaning plate can continuously clean the filter screen during the movement, which can avoid the clogging of the filter screen by impurity particles, thereby ensuring the continuous use of the nozzle.

[0006] As a preferred technical solution, a nozzle flushing assembly and a flushing enhancement assembly are provided on the liquid storage tank, and the operation of the infusion tube is used to provide an operating driving force for the nozzle flushing assembly, and the flushing enhancement assembly is controlled by the operation of the nozzle flushing assembly.

[0007] As a preferred technical solution, the spray pipe flushing assembly includes a cylinder, a piston, a one-way negative pressure pipe, a transmission rod, a sliding hole, an end block, a connecting spring, a storage box, a suction pipe and a delivery pipe;

[0008] Two cylinder bodies are symmetrically installed on the liquid storage tank, and pistons are slidably installed in the two cylinder bodies. The upper part of the cylinder body is connected to the infusion tube through a one-way negative pressure tube, and a transmission rod is installed on the upper part of the piston. A sliding hole is opened on the top of the cylinder body, and the transmission rod passes through the sliding hole and is a sliding fit. An end block is installed on the upper end of the transmission rod, and the end block is connected to the cylinder body through a connecting spring. Two agent storage boxes are symmetrically installed on the liquid storage tank, and the bottom input end of the cylinder body is connected to the agent storage box through an inhalation tube, and the bottom input end of the cylinder body is connected to the upper part of the nozzle body through the infusion tube. The bottom of the nozzle body is The liquid discharging valve is equipped. When the liquid is transported quickly in the infusion tube, the infusion tube can form negative pressure in the cylinder body through the one-way negative pressure tube, so that the piston can move upward in the cylinder body, and the piston can drive the end block to stretch the connecting spring through the transmission rod to move upward synchronously during the movement, so that the cylinder body can suck the detergent in the storage tank through the suction tube. When the piston moves downward and resets under the elastic force of the connecting spring, the detergent in the cylinder body can enter the nozzle body through the infusion tube under the squeezing action of the piston, so that the detergent can be used to flush the impurities attached to the filter screen, and the liquid mixed with impurities can be discharged through the discharge valve.

[0009] As a preferred technical solution, the suction pipe and the delivery pipe are both one-way pipes, and an electric pressure relief valve is installed on the top of the cylinder body. The electric pressure relief valve and the discharge valve are electrically connected to the suction pump. When the suction pump is running, the electric pressure relief valve and the discharge valve are controlled to be closed. When the suction pump stops, the suction pump can control the electric pressure relief valve to open and the discharge valve to open, and the cylinder body can be depressurized, so that the piston can be moved downward and reset, which is conducive to flushing the inside of the detergent spray pipe body.

[0010] As a preferred technical solution, the flushing enhancement assembly includes a slide groove, a slider, a linkage rod, a transmission plate, a transmission shaft, a spiral slide, a fixed ring, a driving ring, a force-bearing shaft and a swivel;

[0011] The two wheels are connected with each other through the two guide rails, and the two guide rails are connected with each other through the two guide rails via a transmission plate. A transmission shaft is installed on the transmission plate, and a spiral slide is provided on the transmission shaft. A fixing ring is installed on the liquid storage tank, and a driving ring is rotatably sleeved in the fixing ring. A force-bearing shaft is rotatably installed in the ring of the driving ring, and the force-bearing shaft is inserted in the spiral slide. A swivel is installed on the driving ring. When the piston moves up, the piston can drive the end block to move up synchronously, and the end block drives the slider to move synchronously in the slide groove through the linkage rod to realize the upward movement of the transmission plate. During the upward movement, the transmission plate can drive the transmission shaft to move up synchronously. Under the squeezing force of the spiral slide on the force-bearing shaft on the driving ring, the driving ring can drive the swivel to rotate counterclockwise, and when the piston moves down, the swivel can rotate clockwise.

[0012] As an optimal technical solution, a curved chamber is provided in the rotating ring, a ball is placed and rolled in the curved chamber, and a touch retraction button is installed at one end of the curved chamber, a fixed block is installed on the liquid storage tank, and a touch extension button is installed on the fixed block. In the initial state, the transmission plate is in contact with the touch extension button, and when the rotating ring rotates counterclockwise, the ball in the curved chamber can roll in the direction away from the touch retraction button under the centrifugal force. When the rotating ring rotates clockwise, the ball can roll in the direction of the touch retraction button under the centrifugal force, so that the ball can press the touch retraction button conveniently.

[0013] As a preferred technical solution, a spiral slope is provided at the bottom of the curved chamber, and the touch retraction button is located at the highest point of the spiral slope, which can ensure that the ball can only touch the touch retraction button when the rotating ring rotates clockwise.

[0014] As a preferred technical solution, the flushing enhancement assembly also includes an electric telescopic rod, a linkage plate, a sliding rod, a perforation and a push plate;

[0015] Two groups of electric telescopic rods are symmetrically installed on the nozzle body, and linkage plates are installed at the ends of the two groups of electric telescopic rods. Sliding rods are installed on the side of the two linkage plates close to the nozzle body. The nozzle body is symmetrically provided with through holes, and the sliding rods penetrate the through holes and are slidably matched. A push plate is installed at the end of the sliding rod away from the linkage plate, and the push plate is in contact with the inner bottom of the nozzle body. The electric telescopic rod is electrically connected to the touch retraction button and the touch extension button. When the ball touches the touch retraction button, the electric telescopic rod can be extended and retracted, which is convenient for the electric telescopic rod to drive the linkage plate to move, so that the linkage plate can drive the push plate to move synchronously through the sliding rod, which is beneficial for the push plate to push the impurities accumulated at the bottom of the nozzle body into the discharge valve, so as to achieve comprehensive cleaning of the inside of the nozzle body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When spray treatment is required, start the suction pump to transport the liquid to the nozzle body. The liquid entering the tube body can be filtered through the filter. At the same time, start the module guide rail to allow the slide to drive the cleaning plate to move back and forth through the connecting rod, so that the cleaning plate can continuously clean the filter, which can prevent impurity particles from clogging the filter, thereby ensuring the continuous use of the nozzle.

[0018] The nozzle flushing assembly set up in the present application can use the negative pressure to make the cylinder body suck in the cleaning agent, and after the spraying is completed, the elastic force of the connecting spring can be used to flush the impurities attached to the filter net with the cleaning agent, making it convenient for the discharge valve to discharge the liquid mixed with impurities.

[0019] The flushing enhancement component set up in the present application can utilize the downward movement of the piston to reset, and the clockwise rotation of the swivel ring allows the ball to touch the touch retraction button, so that the electric telescopic rod can drive the push plate to clean the bottom of the nozzle body, making it convenient to discharge impurities accumulated at the bottom of the nozzle body through the discharge valve, thereby achieving comprehensive cleaning of the inside of the nozzle body.

A cleaning plate 14 is installed on the connecting rod 13, and the cleaning plate 14 is in contact with the upper surface of the filter screen 8. When spraying is required, the suction pump 4 is started, and the liquid in the liquid storage tank 3 can be transported to the nozzle body 5 through the suction tube 6 and the infusion tube 7. The liquid entering the tube body 9 can be filtered through the filter screen 8, which can ensure that the atomizing nozzle 10 continuously and efficiently sprays the liquid. At the same time, starting the module guide rail 11 can allow the slide 12 to drive the cleaning plate 14 to move back and forth through the connecting rod 13, so that the cleaning plate 14 can continuously clean the filter screen 8 during the movement, which can avoid foreign particles from clogging the filter screen 8, thereby ensuring the continuous use of the nozzle.

[0036] The liquid storage tank 3 is provided with a nozzle flushing assembly 15 and a flushing enhancement assembly 16 . The operation of the liquid infusion tube 7 is utilized to provide an operating driving force for the nozzle flushing assembly 15 , and the flushing enhancement assembly 16 is controlled by the operation of the nozzle flushing assembly 15 .

[0037] like Figure 1-Figure 5 and Figure 9-10 As shown, the spray pipe flushing assembly 15 includes a cylinder 1501, a piston 1502, a one-way negative pressure tube 1503, a transmission rod 1504, a sliding hole 1505, an end block 1506, a connecting spring 1507, a storage box 1508, a suction tube 1509 and a delivery tube 1510;

[0038] Two cylinder bodies 1501 are symmetrically installed on the liquid storage tank 3, and pistons 1502 are slidably installed in the two cylinder bodies 1501. The upper part of the cylinder body 1501 is connected to the infusion tube 7 through a one-way negative pressure tube 1503. A transmission rod 1504 is installed on the upper part of the piston 1502. A sliding hole 1505 is opened on the top of the cylinder body 1501. The transmission rod 1504 passes through the sliding hole 1505 and is slidably matched.

Two agent storage boxes 1508 are symmetrically installed on the liquid storage tank 3. The bottom input end of the cylinder body 1501 is connected to the agent storage box 1508 through an aspiration tube 1509, and the bottom input end of the cylinder body 1501 is connected to the upper part of the nozzle body 5 through an infusion tube 1510. A discharge valve 1616 is installed at the bottom of the nozzle body 5. When the liquid is transported quickly in the infusion tube 7, the infusion tube 7 can form a negative pressure in the cylinder 1501 through the one-way negative pressure tube 1503, so that the piston 1502 can move upward in the cylinder 1501, and the piston 1502 can drive the end block 1506 to stretch the connecting spring 1507 through the transmission rod 1504 during the movement to move upward synchronously, so that the cylinder 1501 can suck the detergent in the storage box 1508 through the suction tube 1509. When the piston 1502 moves downward and resets under the elastic force of the connecting spring 1507, the detergent in the cylinder 1501 can enter the nozzle body 5 through the infusion tube 1510 under the squeezing action of the piston 1502, so that the detergent can be used to flush the impurities attached to the filter screen 8, and the liquid mixed with impurities can be discharged through the discharge valve 1616.

[0039] The suction pipe 1509 and the delivery pipe 1510 are both one-way pipes. An electric pressure relief valve is installed on the top of the cylinder body 1501. The electric pressure relief valve and the discharge valve 1616 are electrically connected to the suction pump 4. When the suction pump 4 is running, the electric pressure relief valve and the discharge valve 1616 are controlled to be closed. When the suction pump 4 stops running, the suction pump 4 can control the electric pressure relief valve to be opened and the discharge valve 1616 to be opened, so that the cylinder body 1501 can be depressurized, so that the piston 1502 can be moved downward and reset, which is beneficial to the flushing of the detergent spray pipe body 5.

[0040] like Figure 1-Figure 11 As shown, the flushing enhancement assembly 16 includes a slide 1601, a slider 1602, a linkage rod 1603, a transmission plate 1604, a transmission shaft 1605, a spiral slide 1606, a fixing ring 1607, a driving ring 1608, a force bearing shaft 1609 and a rotating ring 1610;

[0041] The liquid storage tank 3 is symmetrically provided with two slide grooves 1601, and sliders 1602 are slidably installed in the two slide grooves 1601. The sliders 1602 are connected to the end block 1506 through a linkage rod 1603. The two sliders 1602 are connected through a transmission plate 1604. A transmission shaft 1605 is installed on the transmission plate 1604. A spiral slideway 1606 is provided on the transmission shaft 1605. A fixing ring 1607 is installed on the liquid storage tank 3. A driving ring 1608 is rotatably sleeved in the fixing ring 1607. A force-bearing shaft 1609 is rotatably installed in the driving ring 1608. The force-bearing shaft 1609 is inserted in the spiral slideway 1606. A swivel 1610 is installed on the driving ring 1608. When the piston 1502 moves upward, the piston 1502 can drive the end block 1506 to move upward synchronously, and the end block 1506 can drive the slider 1602 to move synchronously in the slide groove 1601 through the linkage rod 1603, so as to realize the upward movement of the transmission plate 1604. During the upward movement, the transmission plate 1604 can drive the transmission shaft 1605 to move upward synchronously. Under the squeezing force of the spiral slideway 1606 on the force shaft 1609 on the driving ring 1608, the driving ring 1608 can drive the swivel 1610 to rotate counterclockwise. When the piston 1502 moves downward, the swivel 1610 can rotate clockwise.

[0042] A curved chamber 1611 is provided in the rotating ring 1610, in which a ball 1612 is placed rollingly, and a touch retraction button 1613 is installed at one end of the curved chamber, and a fixing block 1614 is installed on the liquid storage tank 3, and a touch extension button 1615 is installed on the fixing block 1614. In the initial state, the transmission plate 1604 is in contact with the touch extension button 1615. When the rotating ring 1610 rotates counterclockwise, the ball 1612 in the curved chamber 1611 can roll in the direction away from the touch retraction button 1613 under the centrifugal force. When the rotating ring 1610 rotates clockwise, the ball 1612 can roll in the direction of the touch retraction button 1613 under the centrifugal force, so that the ball 1612 can press the touch retraction button 1613 conveniently.

[0043] A spiral slope is provided at the bottom of the curved chamber 1611, and the touch retraction button 1613 is located at the highest point of the spiral slope, which can ensure that the ball 1612 can only touch the touch retraction button 1613 when the rotating ring 1610 rotates clockwise.

[0044] The flushing enhancement assembly 16 also includes an electric telescopic rod 1617, a linkage plate 1618, a slide bar 1619, a perforation 1620 and a push plate 1621;

[0045] Two groups of electric telescopic rods 1617 are symmetrically installed on the nozzle body 5, and linkage plates 1618 are installed at the ends of the two groups of electric telescopic rods 1617. Slide rods 1619 are installed on the side of the two linkage plates 1618 close to the nozzle body 5. Through holes 1620 are symmetrically opened on the nozzle body 5. The slide rods 1619 penetrate the through holes 1620 and are slidably matched. A push plate 1621 is installed at the end of the slide rod 1619 away from the linkage plate 1618. The push plate 1621 contacts the inner bottom of the nozzle body 5. The telescopic rod 1617 is electrically connected to the touch retraction button 1613 and the touch extension button 1615. When the ball 1612 touches the touch retraction button 1613, the electric telescopic rod 1617 can be extended and retracted, which is convenient for the electric telescopic rod 1617 to drive the linkage plate 1618 to move, so that the linkage plate 1618 can drive the push plate 1621 to move synchronously through the sliding rod 1619, which is conducive to the push plate 1621 pushing the impurities accumulated at the bottom of the nozzle body 5 into the discharge valve 1616, so as to achieve a comprehensive cleaning of the inside of the nozzle body 5.

[0046] Working principle of the present invention:

[0047] When spraying is required, the suction pump 4 is started, and the liquid in the liquid storage tank 3 can be transported to the nozzle body 5 through the suction tube 6 and the infusion tube 7. The liquid entering the tube body 9 can be filtered through the filter screen 8, which can ensure that the atomizing nozzle 10 can continuously and efficiently spray the liquid. At the same time, the module guide rail 11 is started, and the slide seat 12 can drive the cleaning plate 14 to move back and forth through the connecting rod 13, so that the cleaning plate 14 can continuously clean the filter screen 8 during the movement, which can avoid foreign particles from clogging the filter screen 8, thereby ensuring the continuous use of the nozzle.

[0048] When the liquid is transported quickly in the infusion tube 7, the infusion tube 7 can form a negative pressure in the cylinder 1501 through the one-way negative pressure tube 1503, so that the piston 1502 can move upward in the cylinder 1501, and the piston 1502 can drive the end block 1506 to stretch the connecting spring 1507 through the transmission rod 1504 during the movement to move upward synchronously, so that the cylinder 1501 can suck the detergent in the storage box 1508 through the suction tube 1509. When the piston 1502 moves downward and resets under the elastic force of the connecting spring 1507, the detergent in the cylinder 1501 can enter the nozzle body 5 through the infusion tube 1510 under the squeezing action of the piston 1502, so that the detergent can be used to flush the impurities attached to the filter screen 8, and the liquid mixed with impurities can be discharged through the discharge valve 1616.

[0049] When the piston 1502 moves upward, the piston 1502 can drive the end block 1506 to move upward synchronously, and the end block 1506 drives the slider 1602 to move synchronously in the slide groove 1601 through the linkage rod 1603, so as to realize the upward movement of the transmission plate 1604. During the upward movement, the transmission plate 1604 can drive the transmission shaft 1605 to move upward synchronously. Under the squeezing force of the spiral slideway 1606 on the force-bearing shaft 1609 on the drive ring 1608, the drive ring 1608 can drive the rotating ring 1610 to rotate counterclockwise. When the suction pump 4 stops operating, the suction pump 4 can control the electric pressure relief valve to open and the discharge valve 1616 to open, so as to relieve the pressure in the cylinder body 1501. Thereby, the piston 1502 can be moved down and reset, and the swivel 1610 can be rotated clockwise. When the swivel 1610 rotates clockwise, the ball 1612 can roll in the direction of the touch-control retraction button 1613 under the centrifugal force. When the ball 1612 touches the touch-control retraction button 1613, the electric telescopic rod 1617 can be extended and retracted, so that the electric telescopic rod 1617 can drive the linkage plate 1618 to move, so that the linkage plate 1618 can drive the push plate 1621 to move synchronously through the slide bar 1619, which is conducive to the push plate 1621 pushing the impurities accumulated at the bottom of the nozzle body 5 into the discharge valve 1616, so as to achieve a comprehensive cleaning of the inside of the nozzle body 5.
