Description

UV sterilizable filtered water bottle Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a water cup. Background Art

[0002] Drinking cups are common household items that are used frequently. If left unwashed for extended periods, they can easily breed bacteria. Furthermore, the height of most drinking cups makes them difficult to clean thoroughly. Using ultraviolet light to sterilize the cup's interior would alleviate bacterial growth and improve the purity of the water consumed.

[0003] However, the main body and bottom of existing water cups are mostly made of the same material, and are either opaque to ultraviolet light, so that ultraviolet light cannot penetrate and cannot sterilize the inside; or are transparent to ultraviolet light. Although this can be used for sterilization, the ultraviolet light is easily scattered and may cause ultraviolet damage to users.

[0004] Utility Model Content

[0005] The purpose of the utility model is to provide a water cup capable of ultraviolet sterilization to solve the above technical problems.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] A water cup capable of ultraviolet sterilization comprises a water cup body, wherein the water cup body comprises a cup cover, a cup body, and a cup bottom. The invention is characterized in that the cup bottom is made of a material that is transparent to ultraviolet light, and the cup body and the cup cover are made of a material that is not transparent to ultraviolet light.

[0008] The utility model selects the materials of the cup bottom, cup body and cup cover to allow ultraviolet light to be emitted from the cup bottom into the water cup body, thereby performing ultraviolet sterilization on the water in the water cup body. At the same time, the cup body and cup cover are made of ultraviolet-proof materials to prevent ultraviolet light from entering the water cup body from the cup bottom and then passing through the water cup body, thereby causing ultraviolet damage to the user.

[0009] Preferably, the cup bottom is made of polypropylene, and the cup body and the cup cover are made of polyethylene terephthalate.

[0010] Preferably, the cup further comprises a base, wherein the upper end surface of the base is provided with a light outlet, a UV light source is provided below the light outlet, the UV light source is connected to a power module, the cup body is connected to the base, and the light outlet is located below the cup bottom, thereby performing UV sterilization on the cup body through the base.

[0011] Preferably, the outer edge of the base is provided with an upward flange, which is provided with a first thread. The cup body is provided with a downward extension, which is provided with a second thread that matches the first thread. The flange and the extension are threadedly connected. The lower end surface of the extension is lower than the lower end surface of the cup bottom. This allows for a threaded connection between the base and the cup body. The advantages of a threaded connection include a more secure connection and adjustable spacing between the two.

[0012] Further preferably, a push switch is provided on the upper end surface of the base, and the push switch controls the connection of the power module. Thus, the operating state of the ultraviolet light source is linked to the connection state of the water cup body and the base. That is, when the water cup body is placed on the base, the ultraviolet light source operates to sterilize the water cup body. When the water cup body is removed from the base, the ultraviolet light source stops operating, thereby preventing ultraviolet light leakage.

[0013] Preferably, the power module is a battery, and a charging interface is provided on the side wall of the base, and the charging interface is connected to the battery, so that the utility model is not restricted by power supply conditions and can be used outdoors.

[0014] Preferably, an LED light source emitting visible light is further provided below the light outlet, and the LED light source is connected in series or in parallel with the ultraviolet light source, so that the light emission of the LED light source can be used to indicate the working status of the ultraviolet light source.

[0015] Preferably, the upper end of the cup bottom is convex upward, forming a convex lens shape, and the ultraviolet light source is located at the focal point of the cup bottom. This allows the ultraviolet light that enters the water cup body through the cup bottom to propagate more vertically rather than diagonally toward the cup body, thereby reducing the requirements for the cup body material.

[0016] Preferably, a light guide strip made of a light-guiding material is provided on the inner sidewall of the cup body, with the bottom of the light guide strip connected to the cup bottom and the upper portion of the light guide strip extending toward the cup lid. Thus, the light guide strip guides the ultraviolet light to the upper portion of the cup body, preventing the light path from being blocked by structures within the cup body (e.g., a filter element).

[0017] More preferably, the cup further includes a filter element mounted on the light guide bar. The filter element divides the space within the cup body into an upper space for temporarily storing unfiltered water and a lower space for storing filtered water. The filter element is provided with a water outlet connected to a water outlet pipe that passes through the filter element and extends into the lower space. This eliminates the need for a separate filter element holder, thereby reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] Referring to Figures 1, 2, 3, 4, and 5, a water cup capable of UV sterilization comprises a water cup body, a base 4, and a filter element 8. The water cup body comprises a lid 1, a cup body 2, and a cup base 3. The cup base 3 is made of a polypropylene material that is UV-transmissive, such as polypropylene. Transparency for UV light does not require 100% transmittance; a transmittance of 60% or above is sufficient. Some plastic materials can meet this requirement on their own, or some plastic materials can meet this requirement after being reduced in thickness. These are all suitable materials for the cup base in the present invention. The cup body 2 and lid 1 are made of materials that are not UV-transmissive, such as polyethylene terephthalate or a plastic composite. Similarly, some plastic materials can reduce their UV transmittance by increasing their thickness. Transparency for UV light does not require 0% transmittance; a transmittance of less than 30% is sufficient. A light outlet 5 is formed on the upper end surface of the base. A UV light source 10 is located below the light outlet 5 and is connected to a power module. When the cup is connected to the base 4, the base can emit ultraviolet light, which reaches the inside of the cup through the light outlet 5 on the upper end surface of the base to sterilize. This design solves the problem of bacteria breeding inside the cup. Because ultraviolet light is used for sterilization, it is more effective and convenient than traditional water washing.

[0025] The main body of the water cup is connected to the base 4, the light outlet 5 is located below the bottom of the cup, an upward flange is provided at the outer edge of the base, a first thread 11 is provided on the flange, the cup body is provided with a downward extension, the extension is provided with a second thread matching the first thread 11, the flange and the extension thread are connected; the height of the lower end face of the extension is lower than the height of the lower end face of the cup bottom, so that the water cup main body and the base 4 are easy to disassemble.

[0026] Yes, a push switch 7 is provided on the upper end surface of the base, and the push switch controls the connection of the power module; when the cup body and the base are connected, the ultraviolet lamp sterilization can be automatically started because the push switch 7 is pressed.

[0027] The power module may be a battery, and a charging interface is provided on the side wall of the base, and the charging interface is connected to the battery.

[0028] Yes, an LED light source 9 emitting visible light is provided below the light outlet 5 . The LED light source 9 is connected in series or in parallel with the ultraviolet light source 10 . When the ultraviolet light source 10 is started, the LED light source 9 will emit purple light, letting the user know that the ultraviolet light source 10 has been started.

[0029] The upper end of the cup bottom 3 is raised upward, giving it a convex lens shape. The UV light source 10 is located at the focal point of the cup bottom. This allows for a single UV light source 10 to emit parallel light for sterilization, resulting in higher efficiency. The cup body and base are threaded together. This threaded connection allows for an adjustable distance between the cup bottom and the light outlet. By adjusting this distance, the UV light source can be positioned at the focal point of the convex lens-shaped cup bottom, thereby increasing the amount of vertically extending parallel light within the cup body.

[0030] A light guide strip 6 made of a light-guiding material is provided on the inner wall of the cup body. The bottom of the light guide strip 6 is connected to the bottom of the cup, and the upper portion of the light guide strip 6 extends toward the cup lid, so that the ultraviolet light source is not blocked by the filter element. The light guide strip is preferably a body-luminescent light guide strip, so that the ultraviolet light is more evenly distributed within the main body of the water cup.

[0031] The water cup also includes a filter element 8 mounted on the light guide bar 6. The filter element 8 divides the space within the water cup body into an upper space for temporarily storing unfiltered water and a lower space for storing filtered water. The filter element 8 is provided with a water outlet, connected to a water outlet pipe 12. The water outlet pipe 12 passes through the filter element 8 and extends into the lower space, allowing the user to drink the filtered water directly through the water outlet pipe 12. This structure eliminates the need for a filter element holder in the present invention. The filter element can be attached to the cup lid, allowing the cup to be removed and placed as the lid is removed. In this case, a water inlet is required on the cup lid. Alternatively, the filter element can be independent.

[0032] A cup cover can be placed outside the cup body to provide heat insulation and anti-slip performance, and more importantly, to prevent ultraviolet rays from leaking out.
