Description

Technical Field

[0001] This invention relates to the field of car wash machine technology, and more specifically to a home-use wireless car wash machine based on infrared monitoring technology. Background Technology

[0002] Existing cordless car wash machines for home use still have the following drawbacks in practical use:

[0003] Currently, with the booming development of the new energy vehicle industry and the continuous expansion of the new energy vehicle sales market, new energy vehicles are entering thousands of households. As people's demand for cars increases significantly, car maintenance and upkeep costs are also rising. Among these expenses, car washing accounts for the largest proportion. In dusty areas, cars quickly become covered in dust, making car washes expensive and environmentally unfriendly. Furthermore, with various regions experiencing severe droughts and water shortages, car washing is a frequent concern for car owners. Traditional car wash processes typically involve several workers and high-pressure water guns per car, with several workers using the high-pressure water guns to wash the car and then drying it. This consumes a large amount of water, leading to unnecessary waste. It also fails to precisely adjust the water volume according to the area of ​​dirt, or appropriately adjust the nozzles and increase the pressure as needed, otherwise the cleaning effect is poor. Summary of the Invention

[0004] The purpose of this invention is to provide a home-use wireless car wash machine based on infrared monitoring technology to solve the problem that the water volume cannot be accurately adjusted according to the area of ​​dirt, and that the nozzle and pressure cannot be adjusted appropriately as needed, otherwise the cleaning effect will be poor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a household wireless car wash machine based on infrared monitoring technology, comprising an upper housing, a handheld rod and a first guide tube connected to the bottom of the upper housing, a lower base connected to the bottom of the handheld rod, a spray nozzle and a monitoring component connected to one side of the upper housing, and a plunger pump and a second guide tube connected inside the upper housing.

[0006] The monitoring component includes an infrared sensor, an infrared receiver, an infrared transmitter, and a wire. The infrared sensor, infrared receiver, and infrared transmitter are connected to one side of the upper housing, and the wire is connected inside the upper housing.

[0007] Furthermore, the upper housing is composed of multiple housings spliced ​​together, the water spray head is fixedly connected to the upper housing, and a groove is provided on the upper housing above the water spray head, and the monitoring component is connected in the groove.

[0008] Furthermore, the infrared sensor is snapped into a groove in the upper housing, and the infrared receiver and infrared transmitter are respectively fixedly connected to the infrared sensor.

[0009] Furthermore, the side of the infrared sensor away from the spray head is fixedly connected to a wire, and the end of the wire away from the infrared sensor passes through the interior of the upper housing and the handheld handle and is connected to the lower base.

[0010] Furthermore, a motor is fixedly connected to the side of the plunger pump away from the spray head. The plunger pump and the second guide pipe are both snapped into the upper housing. One end of the second guide pipe is fixedly connected to the plunger pump, and the other end of the second guide pipe is fixedly connected to the water pipe inside the spray head. The second guide pipe is sleeved on the outer wall of the motor.

[0011] Furthermore, a foam tank is externally connected to the spray head, and the top of the foam tank is threadedly connected to the spray head.

[0012] Furthermore, the water inlet pipe at the bottom of the plunger pump passes through the upper housing and is threadedly connected to the first guide pipe, with the end of the first guide pipe away from the plunger pump connected to an external water source.

[0013] Furthermore, the top of the handheld lever is fixedly connected to the upper housing, the bottom of the handheld lever is fixedly connected to the lower base, and a switch button is fixedly connected to the outer wall of the handheld lever.

[0014] Furthermore, a circuit board and a battery box are connected inside the lower base, and the circuit board and battery box are snapped into the lower base.

[0015] Furthermore, the circuit board is connected to the top of the battery box, and the top of the battery box has a protrusion extending from it, with the circuit board snapping onto the protrusion extending from the battery box.

[0016] Compared with existing technologies, the home wireless car wash machine based on infrared monitoring technology provided by this invention has the following beneficial effects:

[0017] In this invention, a home-use wireless car wash machine based on infrared monitoring technology connects infrared spectral monitoring technology to the upper housing. The infrared sensor and infrared receiver can detect the degree of dirt on the car and, in conjunction with the motor and plunger pump, can precisely control the water consumption of the wireless car wash machine according to the degree of dirt, thereby saving water and achieving energy conservation and emission reduction.

[0018] The problem of motor overheating has been optimized. By using a second guide pipe fitted on the outer wall of the motor, water entering the plunger pump can be diverted into the second guide pipe. The water in the second guide pipe can cool the motor, avoiding the problem of the motor overheating due to prolonged use. This not only affects the service life of the motor but also reduces the stability of the motor's performance, greatly increasing the practicality of the device. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-6 A home wireless car wash machine based on infrared monitoring technology includes an upper housing 1, a handheld rod 2 and a first guide tube 4 connected to the bottom of the upper housing 1, a lower base 3 connected to the bottom of the handheld rod 2, a spray head 5 and a monitoring component 7 connected to one side of the upper housing 1, and a plunger pump 10 and a second guide tube 11 connected inside the upper housing 1.

[0029] The monitoring component 7 includes an infrared sensor 701, an infrared receiver 702, an infrared transmitter 703, and a wire 704. The infrared sensor 701, infrared receiver 702, and infrared transmitter 703 are connected to one side of the upper housing 1, and the wire 704 is connected inside the upper housing 1.

[0030] The upper housing 1 is composed of multiple housings spliced ​​together. The water spray head 5 is fixedly connected to the upper housing 1. A groove is provided on the upper housing 1 above the water spray head 5. The monitoring component 7 is connected in the groove. The groove provided on the upper housing 1 can fix the monitoring component 7.

[0031] Infrared sensor 701 is snapped into a groove in the upper housing 1. Infrared receiver 702 and infrared transmitter 703 are fixedly connected to infrared sensor 701. Infrared sensor 701, infrared receiver 702, and infrared transmitter 703 connected to the upper housing 1 monitor the area of ​​dirt in the wireless car wash machine. When infrared transmitter 703 is activated, its internal infrared LED emits infrared light. When infrared light shines on the surface of the car, the intensity wavelength distribution of the dust and dirt is different due to the thickness of the dust and dirt, resulting in differences in the emitted infrared light. Infrared receiver 702 measures the degree of absorption of infrared light by the detected substance. As the concentration of the detected substance increases, its ability to absorb light also increases, generating a corresponding electrical signal to obtain basic data, thereby obtaining the dirt condition on the car surface. Infrared sensor 701 controls the operation of the drive device based on the monitoring of infrared transmitter 703 and infrared receiver 702.

[0032] The side of the infrared sensor 701 away from the spray head 5 is fixedly connected to the wire 704. The end of the wire 704 away from the infrared sensor 701 passes through the interior of the upper housing 1 and the handheld rod 2 and is connected to the lower base 3. The infrared sensor 701, the infrared receiver 702, and the infrared transmitter 703 are connected by the wire 704.

[0033] A motor is fixedly connected to the side of the plunger pump 10 away from the spray head 5. Both the plunger pump 10 and the second guide pipe 11 are snapped into the upper housing 1. One end of the second guide pipe 11 is fixedly connected to the plunger pump 10, and the other end is fixedly connected to the water pipe inside the spray head 5. The second guide pipe 11 is sleeved on the outer wall of the motor. The plunger pump 10 and the motor are common models on the market, and will not be described in detail here. Both the plunger pump 10 and the motor are connected to the battery box 9. When the plunger pump 10 is in use, it can draw in external water. The water drawn into the plunger pump 10 is divided through the second guide pipe 11. Part of the water flows out of the plunger pump 10, and the other part flows through the second guide pipe 11 into the outlet of the plunger pump 10 and into the spray head 5. Through the second guide pipe 11 sleeved on the outer wall of the motor, the water entering the plunger pump 10 can be diverted into the second guide pipe 11. The water in the second guide pipe 11 can cool the motor.

[0034] The spray head 5 is externally connected to a foam tank 6. The top of the foam tank 6 is threaded onto the spray head 5. The foam tank 6 connected to the spray head 5 can store cleaning foam. When water passes through the spray head 5, it can be diverted into the foam tank 6 and mixed with the cleaning foam in the foam tank 6. As water enters, the cleaning foam in the foam tank 6 overflows from the foam tank 6 and flows into the spray head 5, where it is sprayed out with the water flow. The foam tank 6 is connected to the spray head 5 by threads, making it more convenient to disassemble and assemble the foam tank 6 when it is necessary to add cleaning foam.

[0035] The water inlet pipe at the bottom of the plunger pump 10 passes through the upper housing 1 and is threadedly connected to the first guide pipe 4. The end of the first guide pipe 4 away from the plunger pump 10 is connected to an external water source. Through the first guide pipe 4 connected to the plunger pump 10, it can be connected to an external water source to provide water for the cordless car wash machine.

[0036] The top of the handheld lever 2 is fixedly connected to the upper housing 1, and the bottom of the handheld lever 2 is fixedly connected to the lower base 3. A switch button is fixedly connected to the outer wall of the handheld lever 2. The handheld lever 2 has a built-in control circuit, which uses an AT89C52 microcontroller as the system microprocessor to control the circuit and process the circuit. The wiring conduit facilitates the delivery of the line to the required location. The wireless car wash machine can be started and stopped by the switch button connected to the handheld lever 2.

[0037] The lower base 3 has a circuit board 8 and a battery box 9 connected inside. The circuit board 8 and the battery box 9 are snapped into the lower base 3. Through the circuit board 8 and the battery box 9 connected to the lower base 3, power can be supplied to the electrical components inside the cordless car wash machine.

[0038] The circuit board 8 is connected to the top of the battery box 9. The top of the battery box 9 has a protrusion. The circuit board 8 is snapped onto the protrusion extending from the battery box 9. The protrusion connected to the battery box 9 can limit the position of the circuit board 8 and fix the circuit board 8, preventing the circuit board 8 from shifting during use and greatly increasing the stability of the device.

[0039] The specific working principle of the home wireless car wash machine based on infrared monitoring technology proposed in this invention is as follows:

[0040] In use, the user first adds cleaning foam to the foam tank 6 and threads the foam tank 6 onto the spray head 5. Then, one end of the first guide tube 4 is connected to an external water source. The user holds the handle 2 and presses the switch button to start the cordless car wash. The infrared sensor 701, infrared receiver 702, and infrared transmitter 703 first monitor the dirt on the car surface. The infrared sensor 701 controls the plunger pump 10 based on the monitoring results. At this time, the plunger pump 10 adjusts the pressure and water flow according to the signal from the infrared sensor 701. Simultaneously, the plunger pump 10 draws water through the first guide tube 4 and then guides the water into the spray head 5 through the plunger pump 10 and the second guide tube 11. The water in the spray head 5 is divided and then combined through the foam tank 6, and finally sprayed out from the spray head 5 to clean the dirt on the car surface.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
