Description

Pet cleaning device

This creation is related to a cleaning device for pets, especially a cleaning device for pets that is automatically separated and automatically cleaned.

Cat litter was invented by Edward Lowe in 1947. Cat litter is mainly used by owners to provide burying feces and urine for their cats. Others include rabbits, ferrets, miniature pigs, and small dogs. Other pets can also use cat litter spontaneously or through training. In addition, cat litter is generally a loose granular substance, which can absorb moisture and odors and be used together with a cat litter box.

However, cat urine contains a substance called "feline urinine", which makes the urine of cats particularly pungent, causing cat litter to be contaminated by long-term contact with urine blocks, which may become a source of indoor odor. At the same time, there are also many cat litters on the market that are advertised as long-term non-replacement and have strong deodorizing power. However, cats have a particularly sensitive sense of smell. Even if cat litter has a powerful deodorizing effect for owners, it is very effective for cats. It may not be the case, and the cat may still refuse to use it, and may even begin to excrete in areas other than the litter box. Therefore, the owner must frequently replace and clean the cat litter, which causes inconvenience in life.

In addition, cat litter generally agglomerates after it is combined with excrement, so it is not suitable to flush it directly into the toilet, which will easily cause the toilet to block and cause difficulty in cleaning the agglomerated cat litter. Although there are cat litter that can be flushed into the toilet, cats’ daily intake of nutrients is different from that of humans, and the feces are often mixed with cat hair, which makes cat’s feces more difficult to dissolve in water. If you flush into the toilet over time, it is still likely to block the water pipe and cause the user to lose money.

Therefore, after observing the above-mentioned deficiencies, the creator of this case came into being.

The purpose of this creation is to provide a cleaning device for pets, which includes a cleaning unit, a drainage unit, and a recovery unit. The cleaning unit injects liquid into the accommodating space of the main body, so that the plural cat litter structures are in the liquid and dirty They are separated from each other, and the dirty liquid is discharged from the accommodating space by the drainage unit, and the cat litter structure is recycled and reused by the recovery unit.

Another purpose of this creation is to provide a cleaning device for pets, which adjusts a cat litter density value of the cat litter structure, and at the same time, the plural dirt has an average dirt density value, and the density value of the cat litter is equal to the density value of the cat litter. The average density value of the dirt is far different, so that the cat litter structure is separated from the dirt in the liquid. In this way, the user can automatically separate the cat litter structure combined with the dirt by the density, so that the separated cat litter structure can be reused, achieving the goals of saving money and environmental protection.

The liquid 23 is separated from each other. In this embodiment, the liquid 23 is liquid water, and the density of the liquid 23 is 1 (g/cm ³ ) when the liquid 23 is liquid water. However, the present creation is not limited to this.

It should be further explained that please refer to FIG. 6, which is a schematic diagram illustrating the structure size and density matching of the cat litter according to the first embodiment of the present creation. According to the first embodiment of the present creation, the cat litter structure 21 finds a better match by adjusting the size, internal hollow volume, wall thickness, and material of the cat litter structure 21, as shown in FIG. 6, and the horizontal axis in FIG. 6 represents the size of the structure 21 of the litter, wherein the size of the larger size indicated number smaller litter structure 21, R _a represents _a line litter size cylindrical type structure 21 of radius, R _b represents a line 21 the hollow interior volume of the structure of litter Cylinder-like radius, the line R _c represents the wall thickness of the cat litter structure 21, and the line R _d represents the preferred plastic density that matches the size, internal hollow volume and wall thickness of the above-mentioned cat litter structure 21, so that the first implementation of this creation is For example, the cat litter structure 21 has a density value of cat litter less than the density of liquid water 1 (g/cm ³ ). It is understandable that the user can choose which size, hollow volume, wall thickness, and material are more appropriate according to their needs. This is only an illustrative description, and this creation should not be construed as limited to this. Thereby, the cat litter structure 21 according to the first embodiment of the invention has ^{a cat litter density value less than the density of liquid water 1 (g/cm 3} ), and the dirt 22 has a dirt average density value greater than the density of water, At this time, when the cat litter structure 21 is combined with the dirt 22 and liquid water is injected into the accommodating space 111, the cat litter structure 21 floats on the water surface due to the low density of the cat litter, and the dirt 22 is caused by the dirt. The average density value is large and sinks to the bottom. In this way, the cat litter structure 21 can be separated from the dirt 22 in the liquid 23 by different densities.

Specifically, according to the first embodiment of the invention, the drainage unit 13 is connected to the main body 11, and the drainage unit 13 is used to drain the above-mentioned liquid 23 from the containing space 111, but the invention is not limited to this.

Specifically, according to the recovery unit 14 of the present creation, it is connected to the main body 11, and the recovery unit 14 is used to recover the cat litter structure 21 from the accommodating space 11, but the present creation is not limited to this.

Specifically, according to the sensing unit 15 of the present creation, which is connected to the main body 11, the sensing unit 15 may be, for example, a weight sensor, an infrared sensor, etc., and the sensing unit 15 is used for Detect whether the pet in the user’s home enters the pet cleaning device 100 according to the present creation, and whether the pet in the user’s home leaves the pet cleaning device 100 according to the present creation, every time a pet in the home enters the pet cleaning device 100 and leaves After the preset time, the above-mentioned cleaning unit 12 and drainage unit 13 are activated to achieve the functions of automatic cleaning and automatic separation. However, this creation is not limited to this.

For example, please refer to FIG. 7, which is a schematic flowchart illustrating the cleaning method of the pet cleaning device according to the first embodiment of the present creation. First, by the sensing unit 15, it is sensed whether the pet in the user’s home has entered the pet cleaning device 100 according to the present invention; then, the cat litter structure 21 contained in the accommodating space 11 is related to the dirt 22 In combination, it can absorb ammonia to deodorize or remove moisture. After that, when the sensing unit 15 senses that the pet leaves the pet cleaning device 100, the cleaning unit 13 is activated after a preset time, and the cleaning unit 13 The liquid 23 is injected into the accommodating space 111 of the main body 11; then, because the density of the cat litter structure 21 is less than the density of liquid water 1 (g/cm ³ ), it floats on the water surface, and the dirt 22 is due to dirt The average density value is greater than the density 1 (g/cm ³ ) of liquid water and sinks to the bottom, so that the cat litter structure 21 is separated from the dirt 22 in the liquid 23; after that, the drainage unit 13 is activated, and the drainage unit 13 will contain The liquid 23 of the dirt 22 is discharged from the accommodating space 111; finally, the recovery unit 14 is activated, and the recovery unit 14 discharges the cat litter structure 21 separated from the dirt 22 from the accommodating space 111 for recovery The cat litter structure 21 is reused.
