Description

PRESSURIZED WATER STORAGE TANK WITH UV LAMP HAVING DISINFECTING FUNCTION
Field of the invention
The present invention relates to the field of water purification, in particular to a pressurized water storage tank having a disinfecting function. Background of the invention
At present, the water storage tanks of all household tank-equipped water purifiers use a sealed gas bag to store pure water. This type of water storage tank mainly consists of a top cover, a bottom cover and a rubber gas bag; the interior thereof has the form of a sunken hollow, the rubber gas bag is located between the top and bottom covers, and the interior space is divided into a water storage tank and a gas charging chamber at the top and bottom. The top cover is provided with a water inlet/outlet; pure water treated by the water purifier flows into the top cover through the water inlet/outlet. The bottom cover is provided with a gas charging valve; gas enters the bottom cover through the gas charging valve. During actual use, the gas charging chamber is charged with gas through the gas charging valve such that the bottom cover has a gas pressure, pure water is introduced into the water storage chamber through the water inlet/outlet and stored, and the rubber gas bag is pressed downwards under the weight of the stored water, such that the volume of the gas charging chamber shrinks, and the relative pressure increases. When a user opens the tap switch to use water, the pressure at the water inlet/outlet decreases, and the rubber gas bag then pushes upward under the pressure of the gas charging chamber. In this way, pure water can be dispensed through the water inlet/outlet, to achieve the function of water storage and pressurized water dispensing.
Due to the presence of a gas bag inside this type of water storage tank, the cost of the latter is high, and the gas bag must be charged with gas to pressurize it in order to enable normal operation. Moreover, the presence of the gas bag makes cleaning of the interior of the water storage tank difficult; bacteria readily grow in the interior if it is not used for a long time. Summary of the invention
One aspect of the present invention provides a pressurizable water storage tank suitable for disinfecting water, comprising a tank body and a disinfecting means which is installed on the tank body and is capable of disinfecting water in the tank body; wherein the disinfection means comprises a disinfection lamp.

Since the water inlet/outlet 3 is disposed at the bottom of the tank body 1 , it can be ensured that all of the water in the water storage tank body 1 can be discharged even though there is no gas bag. During operation, the water storage tank uses the slow rising of the water level in the tank body 1 to compress air inside the tank body 1 , such that pressure is generated inside the tank body 1 and retroacts on pure water stored in the tank body 1 ; the pressure generated is transmitted to the water purifier, and when the pressure value reaches a pressure value set for a pressure switch of the water purifier, the water purifier stops operating.
The disinfecting means 2 comprises a main body 21 with an inner cavity; inside the inner cavity of the main body 21 are provided a battery 22 and a conductive plate 23, as well as a control module 24 connected electrically to the battery 22, and a disinfection lamp connected to the control module 24 via the conductive plate 23. The top of the tank body 1 is provided with a stepped hole for installing the disinfecting means 2, the stepped hole being divided into a first stepped hole 1 1 and a second stepped hole 12 which are connected to each other, and the diameter of the first stepped hole 1 1 being greater than the diameter of the second stepped hole 12; an inner thread is provided on a hole wall of the first stepped hole 1 1. A middle part of the main body 21 is provided with an outer thread which fits the inner thread on the first stepped hole 1 1 , a lower part of the main body 21 is inserted into the second stepped hole 12, and the ultraviolet disinfection lamp 25 is fixed to the lower part of the main body 21.

At the same time, the ultraviolet disinfecting lamp 25 on the disinfecting means 2 is enabled to irradiate the interior of the water storage tank body 1 , realizing disinfection of water in the water storage tank body 1. The control module 24 for controlling operation of the ultraviolet disinfection lamp 25 is provided on the disinfecting means 2, and a pressure sensor for sensing the pressure in the tank body 1 is provided in the water storage tank. Since differences in the amount of water used in the water storage tank will cause different pressures in the water storage tank, different pressures will be released when the amounts of water used by the user are different; thus different pressure values will be generated in the water storage tank, and the pressure sensor transmits these pressure values to the control module 24; the control module 24 can then control the operation of the ultraviolet disinfection lamp 25 according to the pressure values received, to perform disinfection when the internal pressure is lower than a minimum value set for the pressure sensor, and ensure that it can have a rational operation time and a disinfection effect.
