Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a pet water dispenser. Background Technology

[0002] Pet water fountains are devices that provide pets with clean, fresh drinking water. They mainly fall into two categories: one type uses a submersible pump to force water from a bucket into a water tray, where the cat can drink, and the water recirculates through a drain. The other type uses a diaphragm pump to force water from a bucket into a water tray, where the cat can drink, and the water recirculates through a drain. However, submersible or diaphragm pumps are submerged in water, making them prone to bacterial growth. Furthermore, substances in the water can easily carry bacteria and viruses, significantly impacting the pet's health. Although some pet water fountains use filters to filter the circulating water, in long-term use, they often fail to effectively filter bacteria or viruses, or lack sterilization capabilities, making pets like cats and dogs susceptible to illness. Moreover, the materials and components used for sterilization require regular replacement, resulting in high long-term sterilization costs. In addition, wastewater produced by pets after drinking from the water bowl will re-enter the water bucket and participate in the recycling process, causing secondary pollution of the water quality.

[0003] Therefore, how to provide a pet water fountain to improve the safety of its drinking water is a technical problem that this utility model urgently needs to solve. Utility Model Content

Detailed Implementation

[0049] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0050] Example 1

[0051] like Figures 1 to 6 As shown, the first embodiment of this utility model provides a pet water fountain, which mainly consists of a water storage device 3, a heating device 5 for heating the water stored in the water storage device 3, a cooling device disposed above the water storage device 3, and a drinking tray 2 disposed below the cooling device. The water stored in the water storage device 3 is heated by the heating device 5 to form water vapor, which is then cooled and condensed as it flows upward through the cooling tower 1, before falling back into the drinking tray 2.

[0052] As can be seen from the above, in this embodiment, the water stored in the water storage device 3 is heated directly by the heating device 5 to form water vapor. Then, the water vapor released upward is cooled by the cooling tower 1 in the cooling device to form condensate, which then drips back into the drinking tray 2 to provide drinking water for pets such as cats and dogs. Since this pet water fountain does not use any filter material or sterilization 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. This not only saves the tedious steps of replacing filter material or sterilization material, but also saves the cost of cleaning the water.

[0053] In addition, it is worth mentioning that the heating device in this embodiment is preferably a non-contact heating device. Obviously, in practical applications, the heating device can also be directly installed in the water storage device to achieve contact heating.

[0054] In addition, during the evaporation process, the water in the aforementioned water storage device 3 not only plays a role in the high-temperature sterilization of bacteria, but the condensate formed also plays a role in the high-temperature sterilization of the drinking water tray 2 as it falls back to the drinking water tray 2.

[0055] Further preferably, as shown in the drawings, the cooling device is provided with a cooling assembly on the cooling tower 1 to realize rapid condensation of water vapor gathered around the cooling tower 1 and improve the production efficiency of drinking water. The cooling assembly is preferably a refrigeration sheet 5, i.e. a semiconductor refrigeration sheet, which can optimize the internal space structure and improve the condensation efficiency of water vapor. Figure 4

[0056] Further preferably, the cooling tower 1 is provided with a cooling cavity 13 for arranging the cooling assembly, so that the cooling device is hidden in the cooling cavity 13, which not only beautifies the appearance but also protects the cooling assembly and improves the condensation effect.

[0057] Further preferably, the cooling surface of the cooling tower 1 is an annular concave surface 111, which is concave towards the side away from the water storage device 3 to facilitate the gathering of water vapor and the collection of condensed water.

[0058] Further preferably, the top surface 112 and the concave surface 111 of the cooling tower 1 are at least partially parallel to each other, so that the condensation of water vapor by the concave surface 111 can be achieved, and the energy absorbed by the refrigeration sheet 5 can be released to realize the continuous condensation of the concave surface 111 by the refrigeration sheet 5 through the temperature difference between the top surface 112 and the concave surface 111 of the cooling tower 1 and the air temperature difference between them.

[0059] Further preferably, the angle between the cross section of the concave surface 111 in any radial direction and the axial direction of the support body 12 is 30-90°, and the embodiment is only described by taking 45° as an example without specific limitation and elaboration.

The radial cross-section of the drainage surface 21, with an angle between itself and the horizontal plane, gradually increases from the high end to the low end of the water trough and then gradually decreases from the low end to the high end. This allows the water droplets collected in the water dish 2 to flow along the arc formed by the drainage surface 21 from the high end to the low end for accumulation, thus facilitating drinking for the pet.

[0066] Furthermore, as a preferred embodiment, the pet water fountain further includes: a closure opening on the water tray 2, a sealing door assembly 6 for closing and opening the closure opening, and a wastewater tank 41 located below the water tray 2 for collecting the water discharged from the closure opening.
