[0023] like Figure 1 As shown, a hot water supply device for a water dispenser can supply cold water and hot water respectively through multiple pump bodies, thereby reducing the continuous working time of a single pump body, effectively extending the life of the pump body, and further improving the durability of the water supply device, making it convenient to use in places with large flow of people and frequent water supply. The water supply device of this embodiment includes an installation box 1 and a water supply mechanism 2 and a heater 3 arranged in the installation box 1. The installation box 1 is fixedly installed in the water dispenser, so that the water supply mechanism 2 and the heater 3 can be arranged in the water dispenser for water supply. The water supply mechanism 2 of this embodiment is connected to a water source, so that water is pumped into the heater 3, and the water outlet of the heater 3 is connected to the water inlet of the water dispenser, so that the heated water is output for supply.

[0024] like Figure 1As shown, in order to improve the durability of the water supply device, the water supply mechanism 2 of this embodiment includes a first pump body 21 for supplying cold water and a second pump body 22 for supplying hot water. When the user needs cold water, the first pump body 21 can work alone to supply water; when the user needs hot water, the second pump body 22 works alone to supply water, and is heated by the heater 3 and then output, realizing the function of double pumps working alone, reducing the working pressure of a single pump body, thereby improving the durability of the water supply device. The first pump body 21 and the second pump body 22 of this embodiment are both connected to the water inlet of the heater 3 through the water supply pipe 23. The heater 3 can supply cold water and hot water according to the needs of the user. When the user needs hot water, the heater 3 heats the water pumped into the second pump body 22; when the user needs cold water, the heater 3 stops working, so that the water pumped into the first pump body 21 is directly output through the heater 3. In this embodiment, by connecting both the first pump body 21 and the second pump body 22 to the heater 3, when the water dispenser supplies hot water for a long time and causes the second pump body 22 to work for a long time, the first pump body 21 can temporarily replace the second pump body 22 to input water into the heater 3 for heating and outputting hot water; similarly, when the first pump body 21 has been working for a long time, the second pump body 22 can also temporarily replace the first pump body 21 to supply cold water, thereby realizing the alternating operation of the first pump body 21 and the second pump body 22 when the water dispenser supplies water for a long time, avoiding the long-term continuous operation of a single pump body, thereby extending the service life of the pump body and further improving the durability of the water supply device.

[0025] like Figure 1 As shown, the installation box 1 of this embodiment is also equipped with an electric control component 4, which is electrically connected to the first pump body 21, the second pump body 22 and the heater 3, respectively, and can control the first pump body 21, the second pump body 22 and the heater 3 respectively. When the user needs cold water, the electric control component 4 controls the first pump body 21 to start pumping water source and pumping it into the heater 3. At this time, the heater 3 is stationary, and the water pumped by the first pump body 21 is directly output through the heater 3 to achieve the supply of cold water; when the user needs hot water, the electric control component 4 controls the second pump body 22 to start pumping water source and pumping it into the heater 3, and at the same time, the electric control component 4 controls the heater 3 to start heating the water pumped by the second pump body 22 and then output it, so as to achieve the supply of hot water. In this embodiment, the first pump body 21, the second pump body 22 and the heater 3 are powered and controlled by the electric control component 4, so that the first pump body 21 and the second pump body 22 can be started and operated according to different needs, thereby reducing the working pressure of a single pump body.

[0026] Specifically, the electric control assembly 4 of the present embodiment includes a PCB board 41 and a connection seat 42 provided on the PCB board 41 for respectively electrically connecting to the first pump body 21, the second pump body 22 and the heater 3. The first pump body 21, the second pump body 22 and the heater 3 are provided with connection wires, and can be electrically connected to the PCB board 41 by connecting the connection wires to the connection seat 42, so that the PCB board 41 performs power supply and control. The PCB board 41 of the present embodiment is also provided with a heat sink 43, which can dissipate heat from the PCB board 41 to ensure the normal operation of the electric control assembly 4.

[0027] like Figure 2 As shown, in the water supply pipe 23 connected between the second pump body 22 and the heater 3 of this embodiment, a heating wire 231 electrically connected to the heater 3 is provided. The heating wire 231 can initially heat the water pumped into the water supply pipe 23 by the second pump body 22, thereby reducing the heating pressure of the heater 3, improving the heating efficiency, and reducing the waiting time when the user needs hot water.

[0028] like Figure 1 and Figure 3 As shown, in order to realize the installation of the water supply mechanism 2, the heater 3 and the electric control component 4, a partition 11 is provided in the installation box 1 of this embodiment, and the partition 11 divides the interior of the installation box 1 into three installation cavities 12, and the water supply mechanism 2, the electric control component 4 and the heater 3 are respectively installed in each installation cavity 12, which can avoid mutual influence between the water supply mechanism 2, the electric control component 4 and the heater 3, and can avoid water leakage at the connection position between the water supply mechanism 2 and the heater 3, resulting in short circuit damage to the electric control component 4.

[0029] like Figure 3 As shown, the installation box 1 of this embodiment is provided with a heat dissipation hole 13 on the outer wall near the heater 3. The heat generated by the heater 3 when working can be dissipated to the outside through the heat dissipation hole 13, which can prevent the temperature in the installation box 1 from being too high and affecting the normal operation of various mechanisms.

[0030] like Figure 3 As shown, in this embodiment, a clamping piece 14 is further provided in the installation cavity 12 for installing the heater 3, wherein a clamping groove 141 is provided on the clamping piece 14, and the position where the water supply pipe 23 is connected to the water outlet of the heater 3 is clamped into the clamping groove 141, so that the heater 3 can be stably installed in the installation cavity 12, and the clamping groove 141 can clamp the connection position between the water supply pipe 23 and the heater 3 to prevent the water supply pipe 23 from falling off.

[0031] In order to further improve the durability of the water supply device, a filtering component is further provided between the water supply mechanism 2 of the present embodiment and the water source. The filtering component can filter the water drawn by the first pump body 21 and the second pump body 22, thereby reducing debris etc. entering the pump body, reducing the wear of the first pump body 21 and the second pump body 22, and avoiding damage to the heater 3, thereby improving the overall durability of the water supply device. At the same time, it can also improve the cleanliness of the water, thereby ensuring the health of the user.

[0032] like Figure 4 As shown, under normal circumstances, the demand for cold water is high, so in another embodiment, the water supply mechanism 2 also includes a third pump body 5 connected to the water source. When supplying cold water, the third pump body 5 can directly draw water from the water source and supply it to the water inlet of the water dispenser without passing through the heater 3, which can increase the supply speed of cold water. The third pump body 5 of this embodiment is connected in parallel with the first pump body 21 and the heater 3. After the third pump body 5 draws water, it can pass through the heater 3 and be transmitted to the water outlet position of the heater 3. The water supply efficiency is high, and the working pressure of the first pump body 21 and the second pump body 22 can be reduced, thereby extending the working life of the water supply device.

[0033] In summary, the working principle of the present embodiment is as follows: the present embodiment sets up a water supply mechanism 2 with two pump bodies, and connects the first pump body 21 and the second pump body 22 to the heater 3 respectively, and sets up an electric control component 4 to control the first pump body 21, the second pump body 22 and the heater 3 respectively, so that when the water supply device supplies water, the electric control component 4 can control the second pump body 22 and the first pump body 21 to work respectively, so that hot water and cold water can be supplied by different pump bodies respectively, reducing the working pressure of a single pump body, and increasing the service life of each pump body, thereby improving the overall durability of the water supply device, and facilitating use in places with large flow of people and frequent water collection.

[0034] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
