Technical Field

[0001] This utility model relates to the field of high-pressure cleaner technology, and in particular to a wireless high-pressure spray gun and a wireless high-pressure cleaner having the same. Background Technology

[0002] A high-pressure washer is a device that uses high-pressure water jets to clean the surface of objects. It is widely used in homes, industries, commerce, and municipal sectors. It works by pressurizing ordinary water to a very high pressure and then spraying it through nozzles to create a high-speed water jet, thereby achieving the effects of cleaning, removing scale, and removing dirt.

[0003] When using a high-pressure washer, the high-pressure spray gun is removed from the washer and used to clean the area to be cleaned. Because the high-pressure spray gun is at a certain distance from the washer during use, current high-pressure spray guns and washers use fluid pressure potential energy to control the water flow through a valve. However, in actual use, different scenarios require different water flow rates. Current high-pressure washers can only wirelessly control the water flow and cannot determine the water pressure within the spray gun, thus failing to meet user needs. Utility Model Content

[0039] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0040] like Figure 1 and Figure 2 As shown in the illustration, this embodiment provides a wireless high-pressure spray gun 100, including a housing 1, a water spray assembly 2 located within the housing 1, a water pressure sensor, a battery assembly 3, and a display assembly 4. The top of the housing 1 has a first opening 13 and a second opening 14. The battery assembly 3 and the display assembly 4 are respectively installed in the first opening 13 and the second opening 14. The battery assembly 3 is electrically connected to the display assembly 4 to supply power to the display assembly 4. The water pressure sensor is located at the water inlet of the water spray assembly 2 to detect the water pressure in the water spray assembly 2. The display assembly 4 includes a display panel 401, which is electrically connected to the water pressure sensor to display the water pressure parameters in the water spray assembly 2 in real time.

[0041] In this embodiment, a water pressure sensor detects the water pressure in the spray assembly 2 and transmits the water pressure information of the spray assembly 2 to the display assembly 4 in real time. The display assembly 4 then displays the water pressure in the spray gun to the user in real time, allowing the user to know the current water pressure during use and meeting their needs. When using the wireless high-pressure spray gun 100 in different usage scenarios, different water pressures are required. The user can adjust the water pressure according to the displayed water pressure. The adjustment method can be to change to a different sized nozzle or to set parameters on the high-pressure washer to adjust the motor speed, thereby adjusting the required water pressure according to the actual usage scenario. To further improve convenience, the display assembly of the wireless high-pressure spray gun provided in this embodiment also includes a communication module for wireless communication with the washer. When it is necessary to adjust the motor speed and thus the water pressure pumped by the water pump, the communication module can match with the washer and issue adjustment commands, so that the water pressure of the wireless high-pressure spray gun can be adjusted without having to be near the washer.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, the housing 1 includes a left housing 11 and a right housing 121, which together form an accommodating space. The water spray assembly 2 is located within this accommodating space. Multiple coaxial connecting holes 124 are provided on the left housing 11 and the right housing 121. These connecting holes 124 are formed around the sidewalls of the left housing 11 and the right housing 121. Bolts are passed through these coaxial connecting holes 124, and nuts are installed at the other end of the bolts, allowing for a detachable connection between the left housing 11 and the right housing 121. This allows for easy removal of the water spray assembly 2 when maintenance is required.

[0043] Meanwhile, the top of the left housing 11 has a first slot 111 and a second slot 112, and the top of the right housing 121 has a third slot 121 and a fourth slot 122. The first slot 111 and the third slot 121 together form a first opening 13, and the second slot 112 and the fourth slot 122 together form a second opening 14. In this way, when the left housing 11 and the right housing 121 are separated, the battery assembly 3 and the display assembly 4 can also be disassembled, making the overall assembly and disassembly of the spray gun convenient and easy to maintain.

[0044] Specifically, for battery component 3, such as Figure 4 and Figure 5As shown, the battery assembly 3 includes a battery box 306, a mounting shell 304, a waterproof plug 305, a wire 308, and a battery cover 301. The mounting shell 304 is installed in the battery box 306, is used to install the battery 303, and has electrical contacts for conducting the battery 303. The bottom of the mounting shell 304 and the battery box 306 are provided with coaxial wiring holes. The waterproof plug 305 is installed on the bottom surface of the mounting shell 304 and has wiring holes. One end of the wire 308 is electrically connected to the battery 303 in the mounting shell 304, and the other end of the wire 308 passes through the mounting shell 304, the battery box 306, and the waterproof plug 305 and is electrically connected to the display assembly 4 to supply power to the display assembly 4. The battery box 306 has a first mounting opening at its top. A battery cover 301 is placed over the first mounting opening. A first sealing groove 3013 is formed at the bottom of the battery cover 301. A first sealing ring 302 is provided in the first sealing groove 3013. When the battery cover 301 is placed over the first mounting opening, the first sealing ring 302 in the first sealing groove 3013 of the battery cover 301 abuts against the inner wall of the battery box 306. The battery box 306 has a first mounting hole 3063 and a first slot 3061 on opposite sides. The battery cover 301 has a second mounting hole 3012 and a buckle 3011 on opposite sides. The battery cover 301 and the battery box 306 are detachably connected through the first mounting hole 3063, the second mounting hole 3012, the first slot 3061, and the buckle 3011. The outer wall of the battery box 306 is provided with a positioning shaft 3062, and the inner sides of the left housing 11 and the right housing 121 are provided with positioning holes 125. The battery box 306 is installed between the left housing 11 and the right housing 121 through the positioning shaft 3062 and the positioning holes 125.

[0045] The installation process of the battery box 306 is as follows: Install the mounting shell 304 into the battery box 306, set the first sealing ring 302 in the first sealing groove 3013, and then snap the buckle 3011 of the battery cover 301 into the first slot 3061 of the battery box 306. Align the first mounting hole 3063 on the other side of the battery cover 301 with the second mounting hole 3012 on the other side of the battery box 306. After the first mounting hole 3063 and the second mounting hole 3012 are aligned, screw in the locking bolt 307 and fix it with the locking nut to fix the battery cover 301 and the battery box 306 together. Then, after fixing the battery cover 301 and the battery box 306, align the battery assembly 3 with the positioning hole 125 on the left housing 11 and / or the right housing 121 through the positioning shaft 3062 on the outer wall of the battery box 306 and insert it. After the battery assembly 3 and the housing 1 are aligned, fix the left housing 11 and the right housing 121 together with bolts to complete the installation of the battery assembly 3. When maintenance of battery assembly 3 is required, the bolts fixing the left housing 11 and the right housing 121 are removed, the left housing 11 and the right housing 121 are separated, and the positioning shaft 3062 of the battery box 306 is separated from the positioning hole 125 on the housing 1, thus completing the disassembly of battery assembly 3. Battery assembly 3 is easy to install and disassemble, and easy to maintain.

[0046] Specifically, for display component 4, such as Figure 6 and Figure 7As shown, the display assembly 4 also includes an upper housing 402, a lower housing 405, a circuit board 403, a sealing plug 406, and a second sealing ring 404. The upper housing 402 and the lower housing 405 enclose an assembly space. The display panel 401 and the circuit board 403 are installed in the assembly space. The circuit board 403 is electrically connected to the display panel 401, and the display panel 401 is located above the circuit board 403. A wiring hole is provided on the bottom surface of the lower housing 405, and a sealing plug 406 is installed at the wiring hole. The sealing plug 406 has a wiring hole. The wire 308, which is electrically connected to the battery 303 in the battery assembly 3, passes through the wiring hole of the battery box 306 and continues to pass through the wiring hole of the lower housing 405 of the display assembly 4, and finally connects to the circuit board 403 of the display assembly 4 to provide power to the display panel 401. A second mounting port is provided on the top of the upper housing 402, and the display panel 401 is located at the second mounting port. One of the upper housing 402 and the lower housing 405 is provided with a second slot 4021, and the other of the upper housing 402 and the lower housing 405 is provided with a snap-fit ​​block 4051 on its outer side wall. The upper housing 402 and the lower housing 405 are detachably connected through the second slot 4021 and the snap-fit ​​block 4051. The snap-fit ​​block 4051 has a guide surface 40511. The guide surface 40511 gradually tilts away from the second snap-fit ​​groove 4021 in a direction that gradually moves away from the upper housing 402 or the lower housing 405. When the upper housing 402 and the lower housing 405 are assembled, the second snap-fit ​​groove 4021 abuts against the guide surface 40511 of the snap-fit ​​block 4051. As the upper housing 402 and the lower housing 405 gradually approach each other, the contact point between the second snap-fit ​​groove 4021 and the guide surface 40511 of the snap-fit ​​block 4051 gradually moves away from the outer side wall of the upper housing 402 or the lower housing 405. When the second snap-fit ​​groove 4021 passes through the point on the guide surface 40511 of the snap-fit ​​block 4051 that is furthest away from the outer side wall of the upper housing 402 or the lower housing 405, the snap-fit ​​block 4051 snaps into the second snap-fit ​​groove 4021 under the action of slight deformation of the second snap-fit ​​groove 4021. When disassembling the upper housing 402 and the lower housing 405, the user pries the second slot 4021, causing it to deform slightly and move away from either the upper housing 402 or the lower housing 405. This allows the locking block 4051 and the second slot 4021 to separate, thus separating the upper housing 402 and the lower housing 405. Furthermore, the lower housing 405 has a second sealing groove 4052, and a second sealing ring 404 is disposed within this groove. When the upper housing 402 and the lower housing 405 are assembled together, the second sealing ring 404 on the lower housing 405 abuts against the inner wall of the upper housing 402.

[0047] For the connection between display component 4 and housing 1, such as Figure 8As shown, the bottom of the upper housing 402 extends into an assembly portion. A second slot 4021 or a snap-fit ​​block 4051 is provided in the assembly portion. A mounting groove 4022 is formed along the outer side wall of the assembly portion. The housing 1 is provided with a ring of protrusions 123 along the second opening 14. When the housing 1 is disassembled into a left housing 11 and a right housing 121, each of the second slot 112 of the left housing 11 and the fourth slot 122 of the right housing 121 has half of the protrusions 123. The upper housing 402 is detachably connected to the protrusions 123 through the mounting groove 4022.

[0048] The installation process of display component 4 is as follows: Pass wire 308 through the lower housing 405 and connect it to circuit board 403. Connect circuit board 403 to display panel 401. Install the connected circuit board 403 and display panel 401 into the lower housing 405. Then connect the upper housing 402 and lower housing 405 together through the second slot 4021 and the snap-fit ​​block 4051, thus completing the assembly of display component 4. Next, align the mounting slot 4022 of the upper housing 402 of display component 4 with the protrusion 123 in the second slot 112 of the left housing 11, and snap the protrusion 123 into the mounting slot 4022. Then align the protrusion 123 in the fourth slot 122 of the right housing 121 with the mounting slot 4022 of the upper housing 402 and snap it in. After the protrusion 123 and mounting slot 4022 are matched, fix the left housing 11 and right housing 121 together with bolts, thus completing the assembly of display component 4 and housing 1. When it is necessary to disassemble the display component 4, the left housing 11 and the right housing 121 are separated, and the mounting groove 4022 of the upper housing 402 of the display component 4 is separated from the protrusion 123 at the second opening 14 on the housing 1, thus completing the separation of the display component 4 from the housing 1.

[0049] For water spray component 2, such as Figure 9 and Figure 10As shown, the water spray assembly 2 includes a water outlet pipe 201, a third sealing ring 202, a gun valve 203, a fourth sealing ring 204, a valve stem 205, a valve seat 206, a valve 207, a first spring 208, a second spring 211, a gasket 212, a trigger 214, a pin 213, and a trigger 214. The gun valve 203 has two water inlets with perpendicular extension directions. One water inlet is connected to the water outlet pipe 201, and the other water inlet is used to connect to the water inlet pipe. The third sealing ring 202 is disposed at the connection between the gun valve 203 and the water outlet pipe 201, and serves as a seal. The valve stem 205 is located in the gun valve 203. The top of the valve stem 205 abuts against the gasket 212, and the bottom of the valve stem 205 abuts against the valve 207. The valve 207 is spherical. The valve seat 206 is located in the gun valve 203 and abuts against the valve 207 above it. The valve seat 206 has a water passage hole, and the size of the water passage hole is smaller than the diameter of the valve 207. The valve stem 205 passes through the water passage hole of the valve seat 206. The first spring 208 is sleeved on the valve stem 205 and the valve 207. One end of the first spring 208 abuts against the valve seat 206, and the other end of the first spring 208 is limited by the inner wall of the gun valve 203 and remains relatively fixed to the inner wall of the gun valve 203. One end of the valve stem 205 abuts against the valve 207, and the other end of the valve 207 extends out of the gun valve 203 and abuts against the gasket 212. The bottom surface of the gasket 212 abuts against the valve stem 205. The second spring 211 is sleeved on the outer wall of the gun valve 203 and abuts against the bottom surface of the gasket 212. The top surface of the gasket 212 is fixedly connected to the trigger 214. The trigger 214 pin 213 is set on the inner wall of the housing 1, and the trigger 214 can rotate around the trigger 214 pin 213. When the user pulls the trigger 214, the trigger 214 rotates around the trigger 214 pin 213, causing the trigger 214 to press down the gasket 212, thereby driving the valve stem 205 to move downward. When the valve stem 205 moves downward, it pushes the valve 207 to move downward, thereby opening the interior of the gun valve 203. At this time, the water passage inside the spray gun is open. When the user releases the trigger 214, the gasket 212 moves upward under the reset action of the first spring 208 and the second spring 211. At the same time, the valve 207 moves upward under the action of the first spring 208, thereby sealing the inside of the gun valve 203. At this time, the water passage inside the gun valve 203 is closed.

[0050] Furthermore, the water spray assembly 2 also includes a drive unit and a guide block 215. Two symmetrical grooves are opened on the pipe wall of the gun valve 203. The drive unit includes a button 209 and two parallel push-pull rods 210. The external water inlet pipe has grooves on opposite sides that can accommodate the push-pull rods 210. The button 209 is connected to the push-pull rods 210. The two push-pull rods 210 are located in the two grooves respectively. The guide block 215 gradually widens in the direction that gradually moves away from the gun valve 203. After the two push-pull rods 210 pass through the grooves, they abut against the opposite sides of the guide block 215 respectively. When the push button 209 moves, causing the push-pull rod 210 to move, the spacing between the push-pull rod 210 gradually increases under the guidance of the guide block 215. At this time, the push-pull rod 210 can be easily inserted into the groove of the water inlet pipe. Then, the button 209 is released, and the two push-pull rods 210 move in opposite directions under the guidance of the guide block 215. At this time, the push-pull rod 210 has been inserted into the groove of the water inlet pipe, which can firmly fix the water inlet pipe and the spray gun. When it is necessary to remove the water inlet pipe, push the button 209 to move the two push-pull rods 210 toward the guide block 215. During the movement, the spacing between the two push-pull rods 210 increases, and the water inlet pipe can be easily removed.

[0051] In summary, the wireless high-pressure spray gun 100 provided in this embodiment can display the current water pressure to the user in real time during use, making it easy for the user to control the use of the spray gun and meet the user's needs. In terms of structure, the housing 1, battery component 3 and display component 4 are easy to assemble and disassemble, and can be quickly assembled and disassembled and the corresponding parts replaced when maintenance is required, resulting in low maintenance costs.

[0052] This embodiment also provides a wireless high-pressure washer, including a washer body 200, a motor, a water pump, a water inlet pipe, and a wireless high-pressure spray gun as described above. The motor drives the water pump to rotate, and the two ends of the water inlet pipe are respectively connected to the water pump and the wireless high-pressure spray gun 100. The circuit board 403 of the display component 4 has a transmitting module, and the washer body 200 has a receiving module and a control module. The transmitting module and the receiving module communicate wirelessly. The display panel 401 includes a display area 4011 and a control area 4012. The display area 4011 is used to display various parameters of the wireless high-pressure spray gun 100. The display component 4 sends control commands to the circuit board 403 through the control area. The transmitting module sends the control commands to the receiving module of the washer body 200. The receiving module receives the commands sent by the transmitting module and transmits them to the control module. The control module adjusts the speed of the motor, thereby adjusting the speed of the water pump, and thus adjusting the water pressure of the wireless high-pressure spray gun 100.

[0053] In the wireless high-pressure washer provided in this embodiment, the water pressure inside the wireless high-pressure spray gun 100 is collected by a water pressure sensor and displayed in real time on the display area 4011 of the display panel 401 of the display component 4 for user reference. When the user determines that the current water pressure is not suitable for the current usage scenario based on the displayed water pressure, an adjustment command is input through the control area 4012. The circuit board 403 of the display component 4 wirelessly sends the command to the receiving module of the washer body 200. After receiving the command, the receiving module of the washer body 200 sends it to the control module. The control module adjusts the speed of the motor, thereby adjusting the speed of the water pump, and thus adjusting the water pressure of the wireless high-pressure spray gun.

[0054] In summary, the wireless high-pressure washer provided in this embodiment allows for convenient adjustment of the motor speed and water pressure via the display component 4 of the wireless high-pressure spray gun 100. During actual use, the user can determine whether the current water pressure is appropriate based on the reading on the display panel 401. When water pressure needs adjustment, it can be done via the display panel 401 without needing to adjust the water pressure on the washer body 200, making it more convenient to use.
