Description

Technical Field

[0001] This utility model relates to the field of electric spray bottle technology, specifically an electric spray bottle with adjustable water spray force. Background Technology

[0002] An electric sprayer is a gardening or household tool that uses an electric pump to draw water from a container and spray it out in different shapes of water streams or mists through a nozzle. The design of an electric sprayer makes it easy to handle various gardening needs, such as watering plant roots or spraying water on leaves to keep them moist. It is also suitable for household cleaning and is widely used in the car wash industry for convenient spraying of car wash liquid.

[0003] Patent document CN221433521U discloses an electric spray bottle, which includes "a nozzle for spraying water or foam and a body for storing water. The body and nozzle are sealed together. The nozzle has an air pump for pressurizing the body and spraying, and a switch button for pressing to start the air pump. The switch button is exposed on the outside of the nozzle, and the air pump is located inside the nozzle. Pressing the switch button starts the air pump, which injects air pressure into the body, causing the water in the body to spray water or foam outward from the nozzle. This saves the need for manual squeezing to pressurize the air into the body and solves the problem of fatigue caused by manual operation of spray bottles."

[0004] However, the electric sprayers mentioned in the above-mentioned documents mainly address the problems of fatigue caused by manual operation and difficulty in controlling the mixing ratio of gas and liquid.

[0005] Therefore, it is necessary to develop a regulating mechanism to control the mixing ratio of gas and liquid to achieve the desired fineness of the foam. Utility Model Content

[0006] The purpose of this utility model is to provide an electric sprayer that can adjust the spray force, so as to solve the technical problem mentioned in the background art of enabling an electric sprayer to have the function of adjusting the spray force.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electric sprayer for adjusting water spray force, comprising: an electric sprayer body, a liquid supply tank, an electric handle, and a nozzle, wherein the inner wall of the electric sprayer body is provided with an adjustment mechanism, the adjustment mechanism being used to control the mixing ratio of gas and liquid;

[0008] The regulating mechanism includes a liquid pump, an air pump, a liquid supply pump, and a mixing chamber. The liquid pump is located on the inner wall of the electric spray bottle body. A first pipe is installed at the outlet of the liquid pump, with one end extending into the interior of the mixing chamber. A second pipe is installed at the inlet of the liquid pump, with one end extending into the interior of the liquid supply tank. The air pump is located on the inner wall of the electric spray bottle body.

The liquid supply pump is located on the inner wall of the electric sprayer body, and the liquid inlet end of the liquid supply pump extends into the interior of the mixing chamber, and the liquid outlet end of the liquid supply pump extends into the interior of the nozzle.

[0009] Preferably, the top of the electric handle is provided with a control end, the liquid supply tank is located at the bottom of the electric spray bottle body, the electric handle is located on the outer wall of the electric spray bottle body, and the nozzle is located on the outer wall of the electric spray bottle body.

[0010] Preferably, the outer wall of the intake pipe is provided with a filter mechanism, which is used to filter the incoming gas.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses an adjustment mechanism to control the mixing ratio of gas and liquid. Existing electric sprayers cannot achieve better gas and liquid fusion and cannot automatically adjust the gas-liquid mixing ratio to achieve the desired foam density. Therefore, improvements are needed. First, rotating the knob switch drives the first and second control blocks to rotate, thereby controlling the opening size of the two sets of feed troughs and controlling the amount of gas and liquid fed in. Then, the liquid pump works to draw the car wash liquid out through the second pipe and deliver it to the mixing chamber through the first pipe. At the same time, the air pump works to deliver gas to the mixing chamber through the exhaust pipe. The first and second control blocks control the opening size of the feed troughs and control the flow rate, so that the gas and liquid come into contact and fuse better. Then, the liquid in the mixing chamber is delivered to the nozzle by the liquid supply pump, thus completing the spraying of car wash liquid to the outside.

[0017] 2. This utility model filters the incoming gas by installing a filtration mechanism. Existing suction pipes adsorb external gas, but the external gas contains many impurities, which can lead to impurities entering the mixing chamber. Therefore, this needs to be improved. First, two sets of mounting frames are fitted onto the outside of the suction pipe. Then, the threaded rod is twisted to squeeze the extrusion block against the outer wall of the suction pipe, thus installing the filter frame. The HEPA filter is used to filter the gas, which enters the suction pipe through the slots. The HEPA filter is bolted to the filter frame, and the filter frame is easy to disassemble and replace.

[0027] Please see Figure 1 and Figure 2An electric spray bottle with adjustable spray force includes: an electric spray bottle body 1, a liquid supply tank 2, an electric handle 3, and a nozzle 5. The top of the electric handle 3 is provided with a control end 4. The liquid supply tank 2 is located at the bottom of the electric spray bottle body 1. The electric handle 3 is located on the outer wall of the electric spray bottle body 1. The nozzle 5 is located on the outer wall of the electric spray bottle body 1. The liquid supply tank 2 is filled with car wash liquid. Holding the electric handle 3 and pressing the control end 4 causes the liquid pump inside the electric spray bottle body 1 to work, draw and deliver the liquid to the nozzle 5, and then spray the car wash liquid using the nozzle 5. The electric handle 3 has anti-slip texture, which pays more attention to ergonomics.

[0028] Please see Figure 2 , Figure 3 and Figure 4The inner wall of the electric spray bottle body 1 is equipped with an adjustment mechanism to control the mixing ratio of gas and liquid. The adjustment mechanism includes a liquid pump 6, an air pump 9, a liquid supply pump 19, and a mixing chamber 18. The liquid pump 6 is located on the inner wall of the electric spray bottle body 1.

A second pipe 8 is installed at the inlet end of the liquid pump 6, and one end of the second pipe 8 extends into the interior of the liquid supply tank 2. The air pump 9 is located on the inner wall of the electric spray bottle body 1. A suction pump is installed at the air inlet end of the air pump 9. An exhaust pipe 11 is installed at the outlet of the air pipe 10 and the air pump 9, with one end of the exhaust pipe 11 extending into the interior of the mixing chamber 18. A control valve 12 is installed on the outer wall of the exhaust pipe 11, with one end of the control valve 12 extending into the outer wall of the first pipe 7. The inner wall of the control valve 12 is provided with two sets of feed grooves 13. A rotary switch 14 is provided on the outer wall of the electric sprayer body 1. A linkage rod 15 is installed on the outer wall of the rotary switch 14. A first control block 16 is installed on the outer wall of the linkage rod 15. A second control block 17 is installed on the outer wall of the first control block 16. The mixing chamber 18 is located within the electric sprayer. The liquid supply pump 19 is located on the inner wall of the electric spray bottle body 1. The inlet end of the liquid supply pump 19 extends into the interior of the mixing chamber 18, and the outlet end of the liquid supply pump 19 extends into the interior of the nozzle 5. Existing electric spray bottles cannot achieve better mixing of gas and liquid, and cannot automatically adjust the mixing ratio of gas and liquid to achieve the desired foam density. Therefore, improvements are needed. First, rotating the knob switch 14 drives the first control block 16 and the second control block 17 to rotate, thereby controlling the opening size of the two sets of feed troughs 13, and thus controlling the flow rate of gas and liquid. The size is controlled, and then the liquid pump 6 works to draw out the car wash liquid through the second pipe 8 and deliver it to the mixing chamber 18 through the first pipe 7. At the same time, the air pump 9 works to deliver gas to the mixing chamber 18 through the exhaust pipe 11. The first control block 16 and the second control block 17 control the size of the opening of the feed tank 13 and control the flow rate so that the gas and liquid can come into contact and mix better. Then, the liquid in the mixing chamber 18 is delivered to the nozzle 5 through the liquid supply pump 19, thus completing the work of spraying car wash liquid to the outside.

[0029] Please see Figure 3 and Figure 5The outer wall of the intake pipe 10 is equipped with a filter mechanism for filtering the incoming gas. The filter mechanism includes a filter frame 20, a mounting frame 21, and a positioning block 25. The filter frame 20 is located on the outer wall of the intake pipe 10, and the mounting frame 21 is located on the outer wall of the filter frame 20. The inner wall of the mounting frame 21 is provided with a threaded groove 22, and a threaded rod 23 is installed on the inner wall of the threaded groove 22. A HEPA filter screen 27 is installed on the inner wall of the filter frame 20, and a slot 26 is provided on the inner wall of the filter frame 20. A compression block 24 is installed on the outer wall of the threaded rod 23. The positioning block 25 is located on the outer wall of the intake pipe 10, and the positioning block 25 is positioned on the outer wall of the intake pipe 10. Block 25 is provided with two sets. The existing suction pipe 10 adsorbs external gas, but there are many impurities in the external gas, which cause impurities to enter the mixing chamber 18. Therefore, this needs to be improved. First, the two sets of mounting frames 21 are fitted on the outside of the suction pipe 10. Then, the threaded rod 23 is twisted to squeeze the extrusion block 24 against the outer wall of the suction pipe 10, and the filter frame 20 is installed. The HEPA filter 27 is used to filter the gas and enters the suction pipe 10 through the slot 26. The HEPA filter 27 is installed in the filter frame 20 by bolts, and the filter frame 20 is easy to disassemble and replace.

[0030] Working principle: The liquid supply tank 2 contains car wash liquid. Holding the electric handle 3 and pressing the control terminal 4 activates the liquid pump inside the electric spray bottle 1, drawing and delivering the liquid to the nozzle 5. The nozzle 5 then sprays the car wash liquid. The electric handle 3 has anti-slip texture, emphasizing ergonomics. Existing electric spray bottles cannot achieve better mixing of gas and liquid, nor can they automatically adjust the gas-liquid mixing ratio to achieve the desired foam density. Therefore, improvements are needed. First, rotating the knob switch 14 rotates the first control block 16 and the second control block 17, controlling the opening size of the two sets of feed troughs 13, thus controlling the amount of gas and liquid fed in. Then, the liquid pump 6 operates, drawing the car wash liquid through the second pipe 8 and delivering it to the mixing chamber 18 through the first pipe 7. Simultaneously, the air pump 9 operates, delivering gas to the mixing chamber 18 through the exhaust pipe 11. When pump 9 operates for a certain period of time, the first control block 16 and the second control block 17 control the opening size of the feed trough 13, thereby controlling the flow rate, so that the gas and liquid come into contact and mix better. Then, the liquid in the mixing chamber 18 is delivered to the nozzle 5 through the liquid supply pump 19, thus completing the spraying of car wash liquid to the outside. The existing suction pipe 10 adsorbs the outside gas, but there are many impurities in the outside gas, which causes impurities to enter the mixing chamber 18. Therefore, this needs to be improved. First, two sets of mounting frames 21 are fitted on the outside of the suction pipe 10. Then, the threaded rod 23 is twisted to squeeze the extrusion block 24 against the outer wall of the suction pipe 10, thereby installing the filter frame 20. The HEPA filter 27 is used to filter the gas and enters the suction pipe 10 through the slot 26. The HEPA filter 27 is installed in the filter frame 20 by bolts, and the filter frame 20 is easy to disassemble and replace.
