Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a pet drinking fountain. Background Art

[0002] A pet drinking fountain is a device that can provide clean, fresh drinking water for pets. It is mainly divided into two categories. One is to use a submersible pump to press water from a bucket into a water tray. Cats can drink water in the water tray, and the water enters the bucket again through the front drain port for circulation. The other is to use a diaphragm pump to press water from a bucket into a water tray. Cats can drink water in the water tray, and the water enters the bucket again through the front drain port for circulation. However, submersible pumps or diaphragm pumps are soaked in water, which is easy to breed bacteria. In addition, the substances contained in the water are also very easy to carry bacteria, viruses, etc., which greatly affects the health of pets. Although, in actual use, some pet drinking fountains use structures such as filter elements to filter circulating water, but in actual long-term use, there are defects such as difficulty in effectively filtering bacteria, or substances carrying viruses or sterilization, which makes pets, such as cats and dogs, prone to illness, and the materials and devices used for sterilization also need to be replaced regularly, and the long-term sterilization cost is also high. In addition, the waste water produced by pets after drinking in the water dish will re-enter the water bucket to participate in the circulation, causing secondary pollution of the water quality.

[0050] Embodiment 1

[0051] like Figures 1 to 6 As shown, the first embodiment of the present invention provides a pet drinking fountain, which is mainly composed of a water storage device 3, a heating device 5 for non-contact heating of the stored water in the water storage device 3, a cooling tower 1 arranged above the water storage device 3, and a drinking water tray 2 arranged below the cooling tower 1. The stored water in the water storage device 3 is heated by the heating device 5 to form water vapor, and is cooled and forms condensed water when flowing upward through the cooling tower 1, and then falls back into the drinking water tray 2.

[0052] From the above content, it can be known that: in this embodiment, the stored water in the water storage device 3 is directly heated by the heating device 5 to form water vapor, and then the water vapor released upward is cooled by the cooling tower 1 to form condensed water, which then drips back into the drinking tray 2 to be supplied to pets such as cats and dogs for drinking. Since the pet water dispenser does not use any filtering material or sterilizing material, but uses the method of evaporating water and then condensing it, the drinking water obtained can ensure the safety and cleanliness of the water quality, which not only saves the tedious steps of replacing filtering materials or sterilizing materials, but also saves the cost of cleaning water quality.

[0053] In addition, the water in the water storage device 3 not only kills bacteria with high temperature during evaporation, but also the condensed water formed also sterilizes the water tray 2 with high temperature during the process of falling back to the water tray 2.

[0054] Further preferably, Figure 4As shown, the cooling tower 1 is provided with a condensing device to achieve rapid condensation of water vapor gathered around the cooling tower 1 and improve the production efficiency of drinking water.
