Description

Technical Field

[0001] The utility model relates to the technical field of disinfection equipment, in particular to a washing and disinfection structure of a mother and baby disinfection cabinet. Background Art

[0002] The mother and baby disinfection cabinet is a disinfection cabinet specially designed for babies and mothers. It is mainly used to disinfect baby bottles, tableware, toys, clothes and other items.

[0003] For example, the patent with announcement number CN216908679U provides a high-temperature disinfection cabinet, in which a steam generating device is arranged in the cavity at the bottom of the cabinet, and a steam hole is arranged above the steam generating device to communicate with the disinfection cavity. Such high-temperature steam function is more suitable for disinfecting and sterilizing silk fabrics such as baby clothes and napkins.

[0004] For example, the patent with announcement number CN219646321U provides a spray disinfection cabinet, in which a spray device is arranged on the top of the cabinet and a water collecting structure is arranged on the bottom of the cabinet. Such a spray function is more suitable for washing solid objects such as baby toys and tableware with relatively high-pressure water to remove stains and impurities that are difficult to remove on the surface of the object.

[0005] Since the daily necessities for infants and children have high requirements for sterility and are of different types, it is usually necessary to set up multiple sterilization functions in the disinfection cabinet for multi-scenario disinfection. However, there is no disinfection cabinet with both high-temperature steam system and spray system on the market, existing technology and related patents. In addition, installing these two systems in the disinfection cabinet at the same time brings great challenges to the internal structural integration design, water channel design, reducing the total volume of the disinfection cabinet, and increasing the effective volume.

[0006] Therefore, it is urgent to provide a cleaning and disinfection structure of a maternal and infant disinfection cabinet to solve the above technical problems. Summary of the invention

[0007] In view of the problems in the related technology, the utility model proposes a washing and disinfection structure of a mother and baby disinfection cabinet, which has both high-temperature steam function and spray function, and has a compact structure and occupies little space.

[0008] The utility model is achieved in this way:

[0009] A disinfection structure of a mother-infant disinfection cabinet, the mother-infant disinfection cabinet comprising a cabinet body, a cabinet door and a disinfection inner cavity, and also comprising a power module and a disinfection module; the disinfection module comprises a disinfection structure, the disinfection structure comprises a nozzle arranged in the disinfection inner cavity, and a water pump and an evaporator connected to the nozzle in sequence; the water pump is also connected to a built-in water tank or an external water source, and pumps water to the nozzle through the evaporator; the evaporator comprises an evaporation chamber, and a heating module for heating the evaporation chamber, the heating module and the water pump are both connected to the power module, and the heating module heats the water flowing through the evaporation chamber into hot water, vaporizes it, or does not heat it; the disinfection structure also comprises a drainage pipeline, and the drainage pipeline is connected to the bottom of the disinfection inner cavity.

[0010] One end of the drainage pipeline is connected to the disinfection inner cavity, and the other end is connected to the wastewater collection device;

[0011] When the heating module is not working, the water drawn by the water pump passes through the evaporation cavity and is directly sprayed out from the nozzle to rinse the objects to be disinfected, which is the spray function; when the heating module is working, the water passing through the evaporation cavity is heated and converted into warm water, hot water or high-temperature steam, and the nozzle sprays high-temperature steam to sterilize the objects to be disinfected, which is the high-temperature sterilization function.

[0012] The above two functions share the same water channel, which simplifies the structure of the equipment and reduces production costs. At the same time, it also improves the utilization rate of the equipment, and can meet the diverse needs of users and adapt to more usage scenarios.

[0013] As a further optimization of the above solution, the disinfection cavities are multiple, and the multiple disinfection cavities at least include a dry disinfection cavity for storing mother and baby clothes or toys, and a wet disinfection cavity provided with the disinfection structure.

[0014] As a further optimization of the above solution, the nozzle is a rotating nozzle, including a main shaft tube and a diverter head with an inner cavity;

[0015] The flow splitter head comprises a plurality of flow splitters, which are evenly distributed radially on the same plane with a center as a reference; a first spray hole is provided at the end of each flow splitter;

[0016] The input end of the main shaft tube is connected with the evaporation chamber; the output end of the main shaft tube is perpendicular to the plane and penetrates into the inner cavity of the flow divider from the center; the main shaft tube and the flow divider are screwed together.

[0017] When working, the flow splitter head rotates on the main shaft tube, and the fluid flows evenly along the main shaft tube to each flow splitter part and is sprayed out from the first spray hole.

[0018] As a further optimization of the above solution, the end of the diversion portion further has a second spray hole; on the plane, the second spray hole faces the tangent direction of the concentric circle where the center is located.

[0019] When the water pressure of the fluid is relatively high, part of the fluid is sprayed out from the second spray hole, and the generated reverse force drives the flow divider to rotate around the main shaft tube.

[0020] As a further optimization of the above solution, a convex surface is provided at the end of the diversion portion; the first spray hole is provided on the convex surface, is formed into a long strip, and points to the center.

[0021] The convex surface and the long strip shape make the fluid sprayed from the first spray hole be shaped into a fan shape, and the spray distribution is wider and more uniform.

[0022] As a further optimization of the above scheme, the end of the output end of the main shaft tube is formed into a supporting spherical surface with a smooth surface; the diversion part is located on one surface of the inner cavity and is provided with a smooth concave surface, and the main shaft tube faces the smooth concave surface; the curvature of the smooth concave surface is smaller than the curvature of the supporting spherical surface;

[0023] When the flow dividing portion and the main shaft tube are assembled, the smooth concave surface and the supporting spherical surface are in contact with each other.

[0024] There is only one supporting point between the smooth concave surface and the supporting spherical surface. When working, the diverter head only rotates around the supporting point, the friction force is small, and the rotation process is smoother.

[0025] As a further optimization of the above solution, the diverter head is provided with a connection port; at least three vertically protruding and evenly distributed limiting portions are provided along the edge of the connection port, and the ends of the limiting portions are formed into barb portions facing inwards;

[0026] The outer peripheral side of the main shaft tube is provided with an annular convex strip, or an annular flange formed by vertical protrusions; when the diversion part and the main shaft tube are assembled, the main shaft tube passes through the connecting port until the barb part is buckled at the annular convex strip or the annular flange.

[0027] The annular convex strip or annular flange and the barb portion are used together to limit the relative positions of the splitter head and the main shaft tube in the axial and radial directions, so that the splitter head can only rotate relative to the main shaft tube.

[0028] As a further optimization of the above scheme, the bottom end face of the disinfection cavity is provided with at least one obliquely arranged guide surface; the highest position of the guide surface extends to the side wall of the disinfection cavity, and the lowest position is provided with a confluence opening; the confluence opening is connected to the drainage pipeline.

[0029] After spraying or high-temperature steam sterilization, water will accumulate at the bottom of the disinfection cavity; the guide surface and the confluence opening jointly assist in guiding the accumulated water to be discharged quickly.

[0030] As a further optimization of the above scheme, the nozzle is fixed at the central position of the bottom end surface of the disinfection cavity; the number of the guide surfaces is at least three, and the guide surfaces are evenly arranged around the nozzle; and the plurality of confluence openings are evenly distributed on the circumference of the nozzle.

[0031] High-temperature steam is lighter than air and will diffuse upward after being ejected; the nozzle is located at the very center of the bottom of the disinfection cavity, so that the ejected fluid can be most evenly distributed in the disinfection cavity.

[0032] As a further optimization of the above solution, the drainage pipeline includes a water receiving tray, which is fixedly arranged below the disinfection inner cavity and covers the confluence opening;

[0033] The water receiving tray is a concave container with a water inlet and a water outlet at the lowest position; an annular water-blocking baffle is provided on the surrounding side of the water inlet, and the water outlet is located outside the water-blocking baffle; the water-blocking baffle is cooperatively connected with the input end of the nozzle, and the water inlet is connected with the evaporation chamber; the water outlet is used for drainage.

[0034] The water-blocking baffle prevents "waste water" from seeping into the waterway where the water inlet is located.

[0035] As a further optimization of the above scheme, the disinfection cabinet includes an outer shell and an inner lining, the inner cavity of the inner lining is the disinfection inner cavity, and an interlayer is formed between the outer shell and the inner lining; the evaporator and the water pump are both arranged in the interlayer; a bracket is fixedly provided at the bottom of the interlayer, and the upper part of the bracket is connected to the evaporator support so that the evaporator is suspended in the air.

[0036] The bracket isolates the evaporator from the outer shell and the inner liner to prevent high temperature from being directly transmitted to the outer shell and the inner liner and causing damage.

[0037] The beneficial effects are as follows:

[0038] The utility model provides a washing and disinfection structure of a mother and baby disinfection cabinet, including a water pump, an evaporator and a nozzle connected in sequence. According to the needs of the user, the working state of the evaporator is changed so that the liquid passing through the evaporation chamber is directly sprayed out from the nozzle, or the liquid is heated by the heating module into high-temperature steam and then sprayed out, achieving the beneficial effect of one waterway and two functions. Compared with the prior art, the washing and disinfection structure and the disinfection cabinet provided by the utility model have more complete functions, simpler and more compact structures, lower production costs, and the washing and disinfection structure occupies less space in the disinfection cabinet.
