A return spring 17 is fixedly installed in the middle of the support block 16 and the piston block 13. A valve ball 18 is installed in the middle of the support block 16 and the inlet pipe 12.
[0027] The above-mentioned solution is as follows: the microwave oven body 1, microwave oven door panel 2, and glass panel 3 are all existing technologies and are not described in detail in this application. The mounting block 5 inserted into the storage slot 4 is made of PP material, which has good temperature resistance and is non-toxic and odorless. The partition 7 welded and fixed inside the mounting block 5 is made of the same PP material, separating the liquid storage area and the liquid outlet area. The connecting plate 8 set at the top of the mounting block 5 is made of rigid PVC material with a flat surface. The cleaning sponge block 9 threaded at its top is made of high-density polyurethane sponge with uniform internal pores, strong water and liquid absorption, and is not easy to shed residue. The liquid storage chamber 6 opened inside the mounting block 5 is used to store special cleaning agents and is located at the bottom of the partition 7. The liquid inlet hole 21 opened at one end of the mounting block 5 has internal threads on its inner wall. The sealing plug 22 embedded on one side is made of silicone rubber, specifically food-grade silicone, which has strong sealing performance and is resistant to aging. The connecting pipe 10 fixed in the middle of the partition 7 by heat fusion is made of food-grade PE material with a smooth inner wall. The liquid inlet pipe 12 fixed at the bottom of the connecting pipe 10 by heat fusion is made of the same material. The connecting pipe 10 is made of PE material with a diameter adapted to the liquid flow. The outlet pipe 11, which is slidably connected to the top of the connecting pipe 10, is made of PE material. A sealing ring is provided at the point where it passes through the connecting plate 8 to prevent leakage. The outlet of the outlet pipe 11 is in close contact with the cleaning sponge block 9. The piston block 13, which is slidably connected inside the connecting pipe 10, is made of nitrile rubber, which has good elasticity and is solvent resistant. The through hole in the middle is used for liquid flow. The piston block 13 and the outlet pipe 11 are heat-fused and fixed. The cavity 14 in the middle of the outlet pipe 11 and the piston block 13 is a liquid channel. The valve ball 15 inside is made of food-grade 304 stainless steel and its diameter is adapted to the cavity 14. The support block 16, which is heat-fused and fixed inside the connecting pipe 10, is made of PP material. The through hole in the middle is aligned with the inlet pipe 12. The return spring 17, which is fixedly installed in the middle of the support block 16 and the piston block 13, is a stainless steel spring. It is a small cylindrical helical spring with stable elasticity. The valve ball 18 in the middle of the support block 16 and the inlet pipe 12 is made of the same 304 stainless steel ball.
[0028] Reference Figures 1 to 6 The mounting block 5 has symmetrically opened limit grooves 20 inside. The connecting plate 8 has symmetrically fixedly installed limit sliders 19 at both ends, and the limit sliders 19 are adapted to the limit grooves 20. The top of the storage slot 4 is rotatably connected to a sealing plate 23. The sealing plate 23 has symmetrically fixedly installed rotating shafts 26 at both ends. The storage slot 4 has symmetrically opened rotating grooves 25 inside. The rotating grooves 25 have torsion springs 27 fixedly installed inside. One end of the torsion springs 27 is fixedly installed to the rotating shafts 26. Both the sealing plate 23 and the mounting block 5 have pull-out grooves 24 at one end.
[0029] The above solution is adopted: the inner wall of the symmetrically opened limiting groove 20 inside the mounting block 5 is smooth, and the corners are rounded to prevent jamming. The limiting sliders 19, which are symmetrically welded and fixed at both ends of the connecting plate 8, are made of ABS engineering plastic with a smooth surface and are precisely matched with the dimensions of the limiting groove 20. The limiting sliders 19 can slide smoothly along the limiting groove 20. The storage groove 4 is a groove opened at the top of the microwave oven door panel 2. The sealing plate 23, which is rotatably connected to the top of the microwave oven door panel 26, is made of transparent PC material with good light transmission for easy observation of the interior and is impact resistant. The sealing plate 23 is not easily broken. The rotating shaft 26, symmetrically welded and fixed at both ends, is made of stainless steel and its diameter is adapted to the rotation requirements. The rotating groove 25, symmetrically opened inside the storage groove 4, has wear-resistant nylon gaskets on its inner wall to reduce rotational friction. The torsion spring 27, made of stainless steel and a small torsion spring model, is fixedly installed inside the rotating groove 25. It has stable elasticity and strong fatigue resistance. One end of the torsion spring 27 is welded and fixed to the rotating shaft 26. The pull-out groove 24, opened at one end of both the sealing plate 23 and the mounting block 5, has an anti-slip treatment on its inner wall to facilitate finger insertion. The advantage of this structure is that when the cleaning sponge block 9 is pressed to push the liquid outlet tube 11, the connecting plate 8 slides along the limiting groove 20 of the mounting block 5 via the limiting slider 19. The limiting groove 20 provides precise guidance for the limiting slider 19, preventing the connecting plate 8 from shifting and causing misalignment between the liquid outlet tube 11 and the connecting tube 10, ensuring smooth liquid dispensing and avoiding detergent leakage. Under normal conditions, the torsion spring 27 drives the sealing plate 23 to close the storage groove 4 via the rotating shaft 26, preventing dust and oil from entering the storage groove 4 and contaminating the mounting block 5 and the cleaning agent. The cleaning sponge block 9 keeps the components clean and extends their service life. When cleaning the components is needed, the sealing plate 23 can be easily pulled open by pulling out the groove 24 (the torsion spring 27 deforms under force). The installation block 5 can be removed to add cleaning agent or replace the cleaning sponge block 9. The operation is convenient. After the sealing plate 23 is released, the torsion spring 27 automatically resets and drives it to close, without the need for manual return. The cooperation between the limit slider 19 and the limit groove 20 can also limit the sliding stroke of the connecting plate 8, preventing the liquid outlet pipe 11 from moving too far down and causing damage to the piston block 13, thus protecting the internal components.
[0030] Reference Figures 1 to 6 The storage slot 4 is equipped with a heat insulation layer 28 inside;
[0031] The above solution employs the following: the storage slot 4 is a recessed groove at the top of the microwave oven door panel 2. The heat insulation layer 28, which is made of aerogel felt, has uniform thickness, low thermal conductivity, and good temperature resistance, with a long-term temperature resistance of up to 600℃. A PET protective film is also applied to its surface. The advantage of this structure is that when the microwave oven operates, the high internal temperature is generated. The heat insulation layer 28 in the storage slot 4 effectively blocks heat from being transferred to the outside of the storage slot 4 and the internal mounting block 5, preventing the mounting block 5 from softening and deforming due to high temperatures. It also prevents the cleaning sponge block 9 from aging due to heat, ensuring its service life. The low thermal conductivity of the heat insulation layer 28 also prevents localized high temperatures on the surface of the microwave oven door panel 2 due to heat conduction, preventing burns when touched by the user and improving safety. The PET protective film on the surface of the heat insulation layer 28 prevents the aerogel felt material from falling off and facilitates cleaning of the inside of the storage slot 4, keeping the components clean.
[0032] Reference Figures 1 to 6 A handle 29 is fixedly installed on one end of the microwave oven door panel 2;
[0033] The above solution is adopted: handle 29 is prior art and is not described in detail in this application.
[0034] The working principle of this utility model is as follows: During daily use of the microwave oven, the glass panel 3 allows the user to observe the heating of food inside. The mounting block 5 is normally stored in the storage groove 4 at the top of the microwave oven door panel 2. The heat insulation layer 28 inside the storage groove 4 can insulate the heat inside the oven, preventing the cleaning sponge block 9 from being affected by high temperatures. At the same time, the sealing plate 23 tightly covers the storage groove 4 with the torsion spring 27 in the rotating groove 25 through the rotating shaft 26, preventing dust from entering and keeping it clean. When the surface of the glass panel 3 is splattered with oil and needs to be cleaned, the sealing plate 23... Pull out the groove 24 at one end of the mounting block 5, first flip the sealing plate 23 outward, the torsion spring 27 deforms under force, then pull the mounting block 5 out of the storage groove 4, pull out the sealing plug 22 of the liquid inlet hole 21 at one end of the mounting block 5, inject the cleaning fluid into the liquid storage chamber 6 through the liquid inlet hole 21, after injection, re-tighten the sealing plug 22 to prevent leakage, press the connecting plate 8 during cleaning, the limiting sliders 19 at both ends of the connecting plate 8 slide downward along the limiting sliding groove 20 inside the mounting block 5, driving the liquid outlet pipe 11 at the bottom to move downward along the connecting pipe 10, the liquid outlet pipe 11 The piston block 13 is pushed to compress the return spring 17 inside the connecting pipe 10. At this time, the valve ball 15 in the cavity 14 inside the outlet pipe 11 opens under the action of liquid pressure. The cleaning liquid in the storage chamber 6 enters the cavity 14 through the inlet pipe 12, the through hole of the support block 16, the connecting pipe 10, and the valve ball 15 in sequence, and finally seeps out from the outlet of the outlet pipe 11, wetting the cleaning sponge block 9 threaded to the top of the connecting plate 8. After the connecting plate 8 is released, the return spring 17 pushes the piston block 13 and the outlet pipe 11 to reset, and the valve ball 15 automatically closes and stops. The liquid is stopped from flowing out, and at the same time, the valve ball 18 between the support block 16 and the liquid inlet pipe 12 is opened, and the cleaning liquid in the liquid storage chamber 6 is replenished into the connecting pipe 10 to prepare for the next cleaning. Then, holding the installation block 5, the oil stains on the surface of the glass panel 3 are wiped with the cleaning sponge block 9 soaked in cleaning liquid, which can quickly remove the stains and restore the transparency of the glass panel 3 without affecting the subsequent observation of the heating status of the food in the oven. After cleaning, the installation block 5 is inserted into the storage slot 4, the sealing plate 23 is loosened, and the torsion spring 27 drives it to reset and close, completing the component storage.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
