[0002] Soap dispensers are commonly used in homes and hotels, typically mounted on a liquid container. They dispense liquids such as bottled shower gel, shampoo, and hand soap, allowing users to easily dispense a specific amount of soap. These dispensers usually consist of a cap assembly, a dispensing nozzle, and a pump assembly. The nozzle is mounted on one side of the cap assembly. During use, the cap assembly and nozzle are movably attached to the liquid container, while the pump assembly is installed inside the cap assembly and extends into the container. From the overall view, the cap assembly and nozzle are exposed. The user presses the top of the cap assembly, and soap is dispensed from the nozzle. To enhance the product's appearance and create a metallic finish, the cap assembly is often made of plastic and surface-treated with electroplating or spraying. However, this method doesn't achieve the same metallic feel as traditional metal, and electroplating or spraying can cause significant environmental pollution, failing to meet environmental protection requirements. Summary of the Invention

Detailed Implementation

[0012] The present invention provides a soap dispenser, including a cover assembly, the cover assembly including an upper cover 1, the upper cover 1 including an inner liner 11 and a metal shell 12 tightly covering the top and sides of the inner liner 11, the upper cover 1 having an inverted L-shaped through main pipe 13 on the side and bottom, and the upper cover 1 having a liquid outlet pipe 2 and a pump assembly respectively embedded on the side and bottom.

[0013] As attached Figures 1 to 4 As shown, the soap dispenser includes a cover assembly, a dispensing pipe 2, and a pump assembly 3 assembled from top to bottom. When applied to a storage tank, the pump assembly 3 is inserted into the storage tank, while only the cover assembly and the dispensing pipe 2 are exposed. The upper cover 1 constituting the cover assembly is an assembly, in which an inner liner 11 made of easily moldable plastic is located inside, and a metal shell 12 is laminated to the outer surface of the inner liner 11. The metal shell 12 can be tightly bonded by glue or heat sealing. This metal shell 12 tightly covers the top and sides of the inner liner 11, making the inner liner 11 and the metal shell 12 the assembled upper cover 1. The main pipe 13 is an L-shaped channel that runs vertically through the entire main cover body 1. The upper channel opening is horizontally located on the side of the upper cover body 1, through which the liquid outlet pipe 2 enters and connects with the main pipe 13 by passing through the metal shell 12 on the side of the upper cover body 1. The lower channel opening is vertically located at the center of the inner liner 11, with the bottom surface of the metal shell 12 being open, through which the pump assembly connects with the main pipe 13. Because the exposed surface of the upper cover body 1 is covered with a layer of metal shell 12, the surface strength and overall strength of the upper cover body 1 are increased. The surface of the upper cover body 1 is not easily scratched or damaged by sharp objects, nor is it damaged by oxidation, making it more wear-resistant and durable. At the same time, it can fully showcase the metallic feel of the surface of the upper cover body 1, enhancing the product's appearance and texture.

[0014] Preferably, the inner liner 11 includes an upper cover portion 111 and a lower connecting portion 112 with a reduced outer diameter. The metal shell 12 includes a cover 121 covering the cover portion 111 and a cylindrical shell 122 sleeved on the connecting portion 112. The cover 121 is a cover with an open bottom. The upper edge of the cylindrical shell 122 extends outward to form a burr 123, which fits tightly against the bottom surface of the cover portion 111.

[0015] As shown in the attached figure, the inner liner 11 has a T-shaped cross-section. The upper part is a cylindrical cover 111, while the lower part of the connecting part 112 has a narrowed outer diameter, forming a downwardly extending cylindrical connecting part 112. Similarly, the metal shell 12 tightly covers the entire inner liner 11, but is divided into upper and lower parts, which simplifies the processing steps and facilitates the assembly process with the inner liner 11.

[0016] Preferably, the bottom surface of the cover 111 is provided with an upwardly recessed ring 113, and the burr 123 is tightly fitted into the recessed ring 113.

[0017] As shown in the attached figure, on the bottom surface of the cover 111, the inner edge of the concave ring 113 connects to the connecting part 112, and a ring of downwardly extending baffle 114 is left between the outer edge of the concave ring 113 and the outer edge of the cover 111. When the flash 123 of the cylindrical shell 122 is fitted into this concave ring 113, the lower edges of the cover 121 and the baffle 114 and the bottom surface of the flash 123 remain on the same plane, ensuring the integrity of the upper cover 1. At the same time, the baffle 114 can also prevent water from the outer surface of the cover 121 from entering between the cylindrical shell 122 and the cover 111.

[0018] Preferably, the pump body assembly includes a pump head 31 embedded in the main pipe 13 and a pump casing 32 below it. The cover assembly also includes a lower cover 4. The lower cover 4 includes a toothed cover 41 rotatably fitted in the middle of the pump casing 32 and a metal cylinder 42 tightly fitted outside the toothed cover 41. The outer diameter of the top of the metal cylinder 42 is reduced to form an upwardly extending connecting pipe 43. The bottom surface of the connecting part 112 is provided with an upwardly extending clearance groove 115, and the connecting pipe 43 is inserted into the clearance groove 115.

[0019] As shown in the attached diagram, the pump housing cover 41 is a cover that is snapped into the middle of the pump housing 32. It has internal threads for connecting to the storage tank. After being installed on the storage tank, the lower cover 4 is exposed outside the tank. The metal inner cylinder 42 is tightly fitted onto the outside of the cover 41, achieving a tight seal through glue or heat sealing. The connecting pipe 43 is tubular and surrounds the pump head 31. Since the clearance annular groove 115 is an annular groove surrounding the main pipe 13, the top of the connecting pipe 43 extends upwards along the pump head 31 and precisely inserts into the clearance annular groove 115. During operation, the pump head 31 needs to move up and down relative to the pump housing 32, leaving a gap. Existing soap dispensers do not effectively protect this gap, allowing external water or dust to easily enter the storage tank and contaminate the internal soap solution. In this embodiment, since the metal cylinder 42 completely surrounds the pump head 31 and the toothed cover 41, when the upper cover 1 is pressed, the connecting part 112 moves down along with the pump head 31, and the connecting pipe 43 on the metal cylinder 42 always moves within the clearance ring groove 115. Therefore, during use, the metal cylinder 42 is always protected outside the pump head 31 and the pump housing 32, effectively preventing water or dust from entering the liquid storage tank through their gaps.

[0020] Preferably, a foam pad 5 is also fitted below the pump housing 32, abutting against the tooth cover 41 degrees.

[0021] As shown in the attached figure, there is an annular groove 33 above the pump housing 32. The toothed cap 41 is fitted into this annular groove 33. To prevent soap liquid from overflowing from the annular groove 33, a foaming gasket 5 is fitted below the annular groove 33. Since the foaming gasket 5 has a certain elasticity, when the soap dispenser is installed on the storage tank, the foaming gasket 5 is squeezed by the opening of the storage tank, which can just seal the contact surface between the annular groove 33 and the toothed cap 41, effectively preventing soap liquid from overflowing.
