Description

Technical fields:

[0001] This utility model relates to the field of cleaning machine technology, and specifically to an electric heating handheld tableware cleaning device. Background technology:

[0002] Hot water is more effective at cleaning grease when washing dishes after a meal. This is because hot water melts and reduces the viscosity of grease, causing the grease molecules to move faster and the intermolecular forces to weaken, making them easier to rinse away. At the same time, hot water combined with detergent promotes saponification, emulsifying stubborn grease into water-soluble substances. Based on this principle, heated cleaning devices currently on the market include dishwashers and floor scrubbers. See patent number 202211708377.3, titled "Surface Cleaning Device with Steam Delivery," which uses a handheld body suitable for user handling. This handheld body has a main housing, a supply box, and a heater. A flexible hose is installed to the handheld body, and a handheld cleaning tool is installed at the end of the hose. The tool has a liquid distributor for delivering liquid cleaning fluid and a steam distributor for delivering steam. In contrast, dishwashers on the market require preliminary cleaning and rinsing before placing the dishes in the dishwasher rack for further washing, which is costly, complex to operate, and consumes a lot of water, time, and energy. Utility Model Content:

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of existing products and propose an electric heating handheld tableware cleaning device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an electric handheld tableware cleaning device, comprising: a housing with a built-in booster pump and an electric heating unit, and a spray gun connected to the housing via a hose. The housing has an inlet and an outlet. External water is input through the inlet, passes through the booster pump and the electric heating unit in sequence, and is output through the outlet, spraying out water mist or water stream after passing through the spray gun. The spray gun is provided with a water flow channel connected to the hose, and the water flow channel is controlled by a spray gun switch to determine whether it is open or closed. A container for holding cleaning agent is installed on the spray gun, and the container is connected to the water flow channel via an adjustment switch.

[0005] Furthermore, in the above technical solution, the spray gun includes: a gun body, a spray gun pipe, and an adjustable nozzle. The gun body and the adjustable nozzle are connected through the spray gun pipe, and the water flow channel passes through the gun body, the spray gun pipe, and the adjustable nozzle in sequence.

[0006] Furthermore, in the above technical solution, the spray gun pipe is a malleable pipe, such as a universal ball joint pipe, a stainless steel corrugated pipe, or a rubber-coated stainless steel corrugated pipe.

[0007] Furthermore, in the above technical solution, the tank is connected and installed on the gun body or the spray gun pipe via a pipe.

[0008] Furthermore, in the above technical solution, the gun body is provided with a handle for gripping, the water flow channel passes through the handle, and a heat insulation structure is provided at the junction of the handle and the water flow channel.

[0009] Furthermore, in the above technical solution, the water outlet of the tank is connected to a flexible hose via an anti-electric shock wall pipe connector.

[0010] Furthermore, in the above technical solution, a control panel is provided on the housing.

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0023] This utility model relates to an electrically heated handheld dishwashing device. See [link / reference]. Figure 1 As shown, this utility model includes: a spray gun 5 connected to a housing 10 via a hose 4.

[0024] The housing 10 is equipped with a booster pump 1 and an electric heating unit 2. The housing 10 has a water inlet 101 and a water outlet 102. In use, a tap water pipe is connected to the water inlet 101, and external water is input through the water inlet 101, passing through the booster pump 1 and the electric heating unit 2 in sequence, and then output through the water outlet 102, and sprayed out after passing through the spray gun 5.

[0025] The booster pump 1 is a miniature water pump, and a water pressure switch 13 is installed between the booster pump 1 and the electric heating unit 2. The water pressure switch 13 controls the start and stop of the booster pump 1, and the water pressure setting range is 0.2-0.8 MPa. The electric heating unit 2 uses an electronic temperature control heating device, and the water is heated to 30-80℃ after flowing through the electric heating unit 2. A control panel 3 can be installed on the housing 10. The water pressure switch 13 and the electric heating unit 2 are connected to the control panel 3 through a circuit, and the control panel 3 controls the start and stop of the booster pump 1 and the electric heating unit 2, as well as temperature adjustment.

[0026] The housing 1 is powered by an external power source connected to a power plug 31. To prevent leakage, the water outlet 102 of the housing 10 is connected to a flexible hose 4 via an anti-electric shock pipe connector 41. The leakage current of the anti-electric shock pipe connector 41 is ≤30mA.

[0027] This invention uses a booster pump 1 to pressurize the water flow, providing a high-speed water flow. When the water pressure provided by the tap water pipe is sufficient, and the water pressure switch detects that the design water pressure has been reached, the water flow can directly enter the electric heating unit 2 for heating without activating the booster pump 1. Specifically, a one-way water passage 11 with a one-way valve 12 is provided between the water inlet 101 and the electric heating unit 2. A one-way valve 110 is installed on this one-way water passage 11. When the tap water itself has sufficient pressure, there is no need to activate the booster pump 1; water is supplied directly through the one-way water passage 11. That is, the booster pump is only activated when the water supply pressure is insufficient.

[0028] Combination Figure 2 As shown, the spray gun 5 has a water flow channel connected to the hose 4, and the water flow channel is controlled by the spray gun switch 511. The spray gun 5 includes a gun body 51, a spray gun pipe 52, and an adjustable nozzle 53. The gun body 51 is provided with a handle 510 for gripping. The gun body 51 and the adjustable nozzle 53 are connected by the spray gun pipe 52. The spray gun pipe 52 is a malleable tube, such as a universal ball joint pipe, a stainless steel corrugated pipe, or a rubber-coated stainless steel corrugated pipe. Therefore, the spray gun pipe 52 can be bent as needed to clean various hard-to-reach areas. The adjustable nozzle 53 is an adjustable nozzle head, and the user can adjust the direction, flow rate, and spray cone of the water mist as needed. Figure 4 As shown, the water flow from the curved spray gun pipe 52 impacts and cleans the concave bowl 7 from bottom to top.

[0029] The spray gun 5 is generally shaped for easy gripping and operation. The water flow channel passes sequentially through the gun body 51, the spray gun pipe 52, and the adjustable nozzle 53. The water flow channel passes sequentially from the spray gun back through the gun body 51, the spray gun pipe 52, and the adjustable nozzle 53. In this design, the water flow channel does not pass through the handle 510 of the spray gun 5, preventing heat conduction to the handle 510 during operation and ensuring the user is not burned when holding the handle 510.

[0030] Of course, the water flow channel can also pass sequentially from the bottom of the gun handle 510 through the gun body 51, the spray gun pipe 52, and the adjustable nozzle 53. For example... Figure 3 As shown, if this structure is adopted, a heat insulation structure is required. That is, a heat insulation structure is installed in the water flow channel inside the gun handle 510. This heat insulation can be achieved by using an overhead isolation pipe, or by covering the pipe forming the water flow channel with a heat insulation layer.

[0031] Combination Figure 4As shown, this invention features a container 6 for holding cleaning agent. The container 6 is mounted on a spray gun 5, and is connected to a water flow channel via an adjusting switch 61. To adjust the pressure, the container 6 is provided with a pressure regulating hole 62. Specifically, in this invention, the container 6 is connected to the gun body 51 or the spray gun pipe 52 via a pipe. When in use, as water flows through the water flow channel on the spray gun 5 and exits from the adjustable nozzle 53, the adjusting switch 61 is activated as needed. The negative pressure generated by the high-speed water flow draws the cleaning agent from the container 6 into the water flow channel through the adjusting switch 61, forming a water mist mixed with the cleaning agent that is then sprayed out.

[0032] When using this invention, after connecting the water and power sources, the booster pump 1 starts and stops when the water pressure reaches the designed value. Once the water temperature is set to an appropriate level, the electric heating unit begins heating the corresponding water, stopping when the set temperature is reached. The user holds the spray gun 5 and controls the water flow channel via the spray gun switch 511, allowing the hot water stream or spray generated by the spray gun 5 to rinse the tableware. The high-speed hot water mist has a strong cleaning effect on oil stains, effectively cleaning most tableware directly. If stubborn oil stains remain, the adjustment switch 61 on the tank 6 is turned on to add detergent to the spray for rinsing. Then, depending on the cleaning results, the detergent supply is turned off, and a final rinse with pure hot water mist is performed.

[0033] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
