Description

Instant sterilizing structure of water dispenser

The present invention provides an instant sterilization structure of a water dispenser, especially an instant sterilization structure of a water dispenser capable of effectively achieving an instantaneous sterilization effect by limiting the flow channel space and extending the distance of the water flow by the spiral member and increasing the reflection surface area of the light. .

Modern society is paying more and more attention to food hygiene. The water quality requirements for drinking water are gradually increasing with the health awareness. In addition to removing heavy metals or impurities from the water, bacteria in the water should be further eliminated. However, existing drinking fountains In addition to sterilization of hot water, there is a problem of bacterial growth at room temperature and ice water. As shown in Fig. 6, the ultraviolet sterilization device (Ultraviolet, abbreviated as UV) is taken as an example. The existing ultraviolet sterilization device 90 includes a casing 91. And a UV lamp 92, the inner side of the housing 91 reflects light. The housing 91 has an opposite water inlet 93 and a water outlet 94. The UV lamp 92 can be installed inside the housing 91. When the ultraviolet light is emitted, a water-receiving space 95 is formed between the casing 91 and the UV lamp 92. The user installs the ultraviolet ray sterilizing device 90 on a water dispenser (not shown), and the water passes through the water inlet 93. The water flows into the housing 91 and flows into the water receiving space 95. The UV lamp 92 emits ultraviolet light to sterilize the water in the water receiving space 95 to achieve a sterilizing effect.

However, the conventional ultraviolet ray sterilizing device 90 irradiates the water stored in the water permeable space 95 by the UV lamp 92 in the casing 91, because the distance between the casing 91 and the UV lamp 92 is wide, and the water If the flow rate is too large, the flow path is too short, and it must be irradiated for a long time to achieve the purpose of sterilization. The result of long-time irradiation of the UV lamp 92 causes the water temperature to rise, unable to provide normal temperature and ice water to the user, and when the water dispenser is pressed immediately to let the water flow out. At the time, the water filled in from the water inlet 93 does not have enough time to sterilize, and the casing The distance between the 91 and the UV lamp 92 affects the energy of the water to be irradiated by the ultraviolet light. The effect of sterilizing the water closer to the casing 91 is different from the effect of sterilizing the water closer to the UV lamp 92, and the uniformity is not uniform. The water flowing through the water receiving space 95 is completely sterilized.

The main purpose of this creation is to provide an instant sterilization structure of the water dispenser, so as to improve the water of the existing ultraviolet disinfection device that needs to continuously irradiate the water space, and the inability to effectively sterilize due to lack of time and to provide immediate drinking, and the energy of the ultraviolet light to receive the water space. The wide distance affects the problem that the water flow will irregularly affect the energy of ultraviolet light and cannot be uniformly sterilized.

The spiral member abuts the inner side of the cylindrical body and the outer side of the quartz sleeve, so that the cylindrical body A spiral flow path is formed between the quartz sleeve.

The instant sterilization structure of the creation water dispenser is set at the water outlet end of the water dispenser, and can be instantaneously sterilized when the user presses the water dispenser to make it water. The instant sterilization structure of the creation water dispenser provides the function of instant sterilization by the following units:

1.

The bactericidal effect.

2. When water flows in from the water inlet of the outer casing, water flows into the flow channel space of the cylinder of the reflective light sleeve, and water flowing into the flow channel space enters the spiral flow path along the spiral member. The spiral flow path increases the distance that water flows outside the quartz sleeve, prolonging the time the water is exposed to ultraviolet light, and the ultraviolet light has sufficient time to kill bacteria and viruses in the water.

3. The cross section of the spiral is rounded, and the spiral is made of a metal material, the surface of the metal material can reflect light, and the ultraviolet light is irradiated to the spiral to reflect the ultraviolet light, so that The spiral flow path is filled with ultraviolet light, and the water can be sufficiently and uniformly irradiated with ultraviolet light to effectively kill bacteria and viruses in the water.
