Description

    TECHNICAL FIELD
  • The present invention relates to a fog machine, and particularly to a fog machine with continuous water supply.
    • BACKGROUND
  • In conventional fog machines, the fog generating chamber is formed by the entirety of the inner chamber of its main body. In this configuration, high water level will adversely affect fog generating effect, while low water level means a pool water storage capacity, which requires frequent water re-supply. Since the water tank and the fog generating chamber is in the same chamber, a large amount of fog as generated will flow out when the water re-supply window is opened, making it difficult to find out the water supply point to successfully supply water. In this case, the fog spraying has to be stopped to allow for water re-supply, and then re-started after the water re-supply is completed. Therefore, a continuous fog spray cannot be achieved. Frequent water re-supply requires frequent stop of fog spray, such that a stage effect with continuous fog spray can hardly be obtained.
  • EP 3 181 242 discloses a fluid dispersal device wherein the provision of fluid is controlled by a fluid level sensor which is adapted to determine a fluid level and to hold the fluid level at an optimum. A fluid level and flow control system, comprising the fluid level sensor and the fluid pump, ensures that the required level of fluid is maintained within the tank unit during operation. The fluid level sensor is adapted to control the fluid pumps. The fluid level is maintained by the fluid level sensor first detecting the fluid level and then controlling the fluid pump to pump the fluid in or out.

  • As shown in Figs. 1, 2, and 3, the present invention provides a fog machine with continuous water supply, comprising: a main body 11 provided with a fog outlet 12, a circuit board 13 provided inside the main body, a water tank 15 provided at the bottom of the main body, a fog generator 16 provided in the water tank 15 and electrically connected with the circuit board 13, a water reservoir 21 provided above the water tank, a water filling port 22 provided at the bottom of the water reservoir 21, and a water filling switch 23 provided at the water filling port and controlled by the water level of the water tank, wherein the space above the water tank is in communication with the fog outlet 12. The water reservoir 21 is provided above the water tank 15 and the water filling switch 23 controls the water in the water reservoir 21 flowing into the water tank 15, wherein the opening and closing of the water filling switch 23 depends on the water level of the water tank 15. If the water lever becomes low, the switch is automatically opened and thereby the water supply is started, allowing the water in the water reservoir 21 flow into the water tank 15 through the water filling port 22, such that it can be assured that the water level in the water tank 15 is sufficient to immerse the fog generator 16 and thereby fog generating can be continuously conducted. When a certain water level is reached, the switch is automatically closed and thereby the water supply is stopped, such that a sufficient amount of water can be stored in the fog machine to be continuously supplied to the water tank 15. The water tank 15 which functions as a fog generating area is separated from the water reservoir 21, such that the fog will not flow into the water reservoir 21 and thus will not influence adding water from outside into the water reservoir 21 during the fog generating process. When the water level in the water reservoir 21 becomes low, the coverplate 28 of the water reservoir 21 can be directly opened to allow for adding water, without causing any influence on the fog generating process in the water tank 15. Therefore, the fog generating process does not need to be stopped during the process of adding water, and thus the fog generating process can be conducted continuously. The fog generation does not influence the water addition, and the water addition does not influence the fog generation.
  • The water filling switch 23 comprises a floating element provided in the water tank 15 and capable of moving up and down along with the water level in the water tank, and a blocking element 25 fixedly connected with the top of the floating element and capable of extending into and blocking the water filling port 22. In this embodiment, the floating element moves up and down along with the water level in the water tank. When it moves down, it draws the blocking element away from the water filling port 22 so as to open the switch, and when it moves up, it forces the blocking element 25 to block the water filling port 22 so as to stop the water supply.
  • Further, the floating element can be a floating platform or a floating ball provided in the water tank 15. The floating platform or floating ball is supported by the buoyancy of water, such that the floating platform or floating ball moves up and down along with the water level. Alternatively, the floating element can also be a floating cap 26 provided upside-down in the water tank 15, which can also move up and down along with the water level. The floating cap 26 can be a semi-closed floating platform.

Therefore, a suitable water level can be maintained to facilitate better generation of fog, and auto-supply of water can be provided to allow for continuous fog generation.
