However, this way increases the cooling fan as a component, increases the overall cost of the product and the overall installation of the product, and the cooling effect of this cooling method is also general. UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the deficiencies of the prior art, and provides an improved structure of instant heating type heating device which is convenient for the cooling of the circuit board and has a relatively simple overall structure.

[0005] The utility model relates to heating equipment technical field, concretely relates to an improved structure of instant heating type heating device.

[0006] An improved structure for an instant heating device includes a frame, an instant heating tube, and a circuit board. Both the circuit board and the instant heating tube are fixed to the frame and electrically connected. One end of the instant heating tube is connected to a water inlet pipe, and the other end has a hot water outlet. The device is characterized by a comprehensive water tank installed on the water inlet pipe, the inner cavity of which is connected to the water inlet pipe. One end of an electrical component on the circuit board is fixed to a heat sink, which is placed on the comprehensive water tank. This improved structure utilizes the comprehensive water tank on the water inlet pipe and the heat sink of the electrical component to achieve heat exchange between them. This not only dissipates heat from the heat sink, facilitating stable operation of the electrical components, but also raises the temperature of the comprehensive water tank, providing a preheating effect. Furthermore, it eliminates the need for additional cooling devices such as fans, resulting in a simpler overall product structure.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] Specifically, a portion of the heat sink extends into the inner cavity of the integrated water tank, allowing the heat sink to directly contact the water in the integrated water tank for heat exchange, thereby improving the heat exchange efficiency between the two and enhancing the heat dissipation effect of the heat sink and the preheating effect of the water in the inner cavity.

[0009] Specifically, the integrated water tank includes a tank body and a top cover. The tank body has an inner cavity, and the top cover is closed on the upper opening of the inner cavity. The heat dissipation component is placed on the top cover, and a part of the heat dissipation component passes through the top cover and extends into the inner cavity. This allows the heat dissipation component to directly contact the water in the inner cavity. At the same time, the structure of the integrated water tank is relatively simple and its implementation is relatively easy.

[0010] Specifically, it further includes an anti-dry-burning detection device, which is placed on the top cover and electrically connected to the circuit board. If the anti-dry-burning detection device detects that no water is flowing through the integrated water tank, that is, the water inlet pipe does not supply water to the instant heating tube, the anti-dry-burning detection device sends a signal to the circuit board, causing the circuit board to control the heating tube to stop working, thereby preventing the heating tube from dry-burning.

[0011] Specifically, the upper part of the cover extends upward to form an upper enclosure wall, and the upper enclosure wall forms an inner recess. A through hole is opened at the bottom of the mounting recess. The anti-dry burning detection element is placed on the mounting recess, and the detection head of the anti-dry burning detection element passes downward through the through hole and extends into the inner cavity. This allows the anti-dry burning detection element to directly and stably detect whether water passes through the inner cavity. At the same time, the mounting recess provides a stable installation space for the anti-dry burning detection element, which is conducive to the stable operation of the anti-dry burning detection element.

[0012] Specifically, the heat sink is a T-shaped aluminum heat sink, and the upper cover extends upward to form a hollow support portion. The upper part of the aluminum heat sink is placed on the hollow support portion, and the lower part of the aluminum heat sink extends into the inner cavity. Electrical components are connected to the upper part of the aluminum heat sink. The hollow support portion can both realize the installation of the aluminum heat sink on the upper cover and allow the lower part of the aluminum heat sink to extend into the inner cavity. Its structure is ingenious and has a good implementation effect.

[0013] Specifically, the water inlet pipeline includes a first water pipe and the integrated water tank. The first water pipe is fixed on the frame, one end of the first water pipe is connected to one end of the instant heating pipe, and the other end of the first water pipe is connected to the tank. The inner cavity of the tank is connected to an external water source. The integrated water tank can act as an intermediate transmission carrier for the external water source, so that the water inlet pipeline can achieve better heat exchange and water inlet detection functions. At the same time, the integrated water tank is connected to the instant heating pipe through the first water pipe, which has a good implementation effect.

[0014] Specifically, it further includes a water pump, and the inner cavity is provided with a partition to divide the inner cavity into a detection space and a heat exchange space. The anti-dry-burning detection element is located above the detection space, a part of the heat dissipation element extends into the heat exchange space, the water pump is fixed on the frame and the water pump inlet is connected to the detection space, and the water pump outlet is connected to the heat exchange space. The partition divides the inner cavity into two independent spaces, which is conducive to the independent and stable implementation of the detection of the anti-dry-burning detection element and the heat exchange of the heat dissipation element. Furthermore, the water pump enables water communication between the detection space and the heat exchange space, which also allows the water inlet pipe to stably deliver water to the instant heating pipe.

[0015] Specifically, it further includes an elastic electrode clamp, which is sleeved on the outer periphery of the instant heating tube and electrically connected to the circuit board. The elastic electrode clamp has an elastic opening. The frame includes a left shell and a right shell connected to each other. The left shell has a left limiting part, and the right shell has a right limiting part. The portion of the elastic electrode clamp located to the left of the elastic opening abuts against the left limiting part, and the portion of the elastic electrode clamp located to the right of the elastic opening abuts against the right limiting part. The elastic electrode clamp is restricted and fixed by the cooperation of the left limiting part and the right limiting part, so that the elastic electrode clamp can be stably installed on the outer periphery of the instant heating tube. That is, the elastic electrode clamp can be fixed on the instant heating tube by the connected left shell and right shell. Its design is ingenious and has a good implementation effect.

[0016] Specifically, it further includes a thermostat, one end of which is close to the instant heating element, and the other end of which is soldered to the circuit board; this enables an electrical connection between the thermostat and the circuit board, making the thermostat and the circuit board more compact and reducing the overall size of the product.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This instant heating device has an improved structure. It utilizes the integrated water tank on the water inlet pipe to cooperate with the heat dissipation components of the electrical components to achieve heat exchange between the integrated water tank and the heat dissipation components. This not only achieves heat dissipation of the heat dissipation components, which is beneficial to the stable operation of the electrical components, but also raises the temperature of the integrated water tank and has a certain preheating effect on the water in the integrated water tank. Furthermore, it can achieve heat dissipation of the electrical components without the need to add fans or other heat dissipation devices, making the overall structure of the product relatively simple.

[0019] (2) The integrated water tank can act as an intermediate transmission carrier for external water sources, so that the water inlet pipeline can achieve better geothermal exchange and water inlet detection functions. At the same time, the integrated water tank is connected to the instantaneous heating pipe through the first water pipe, and its implementation effect is good.

[0020] (3) The elastic electrode clamp is fixed by the cooperation of the left limiting part and the right limiting part, so that the elastic electrode clamp can be stably installed on the outer periphery of the instant heating tube. That is, the elastic electrode clamp can be fixed on the instant heating tube by the connected left and right shells. The design is ingenious and the implementation effect is good.
