Detailed Description

In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Mite-removing instruments, also called mite-removing dust collectors, are cleaning devices for cleaning dust, mites and other allergens on textile articles such as beds, sofas, carpets, clothes and the like, and are increasingly used. Dust mites are a tiny organism that mainly live in mattresses, pillows, carpets, furniture, curtains, etc., and their excretions and carcasses are common allergens that can cause asthma, rhinitis, and other allergic reactions.

The mite removing instrument generally has several working principles for removing mites, and is specifically as follows:

Suction force: most mite control instruments are equipped with a powerful suction system that is able to draw dust mites and their excretions deep into the fabric fibers. Such suction is typically stronger than in household cleaners because they need to penetrate deeper levels to effectively remove dust mites.

Ultraviolet (UV-C) sterilization: some high-end acarina devices are equipped with ultraviolet lamps that emit ultraviolet light at the UV-C wavelength that is capable of destroying DNA of microorganisms, thereby killing dust mites and other microorganisms. However, ultraviolet rays need to be directly irradiated to dust mites to be effective, and thus their effect may be limited.

Hot air: part of the mite removing instrument can also use a hot air function, and the temperature of the fabric is increased by heating air, so that the survival environment of dust mites can be reduced, and the dust mites are not easy to survive at high temperature.

Vibration or beating: some mite removing instruments are designed with vibration or beating functions, and through high-frequency vibration or beating of the surface of the fabric, deep dust mites and dirt can be loosened and dispersed, so that the dust mites and dirt can be more easily captured by a suction system.

HEPA filtration system: in order to prevent dust mites and allergens from being re-released into the air during cleaning, many mite removal instruments are equipped with High Efficiency Particulate Air (HEPA) filters. Such filters can capture very small particles, including cadavers and excretions of dust mites.

The mite removal instrument is used for cleaning regularly, and the following benefits are achieved: allergen reduction dust mites and their excretions are common allergens that can lead to asthma, rhinitis, dermatitis and other allergic reactions. The mite removing instrument can effectively reduce the existence of the allergens, thereby reducing the occurrence of allergic symptoms. Improving the indoor air quality, the acarid remover helps to improve the cleanliness of the indoor air by cleaning acarids and their excretions, which is especially important for people with respiratory problems. The mite removing instrument is used regularly to reduce the living environment of dust mites and prevent the breeding and reproduction of dust mites. Improving sleep quality, mattresses, pillows and sheets are the most common habitat for dust mites. Cleaning these areas with an acarid eliminator can help reduce the chance of exposure to allergens at night, thereby improving sleep quality. Extending the useful life of furniture and fabrics, dust mites and their excretions can cause discoloration and damage to the fabrics. Regular cleaning can keep furniture and fabrics clean and fresh, and prolong their service life.

When the mite-killing dust collector is used for cleaning, the bottom surface of the suction inlet of the mite-killing dust collector is contacted with the surface to be cleaned, so that dust, mites and other allergic sources are sucked into the dust cup of the mite-killing dust collector. The mite-killing dust collector comprises a machine body, and a fan and a rolling brush which are arranged in the machine body. When the mite removing instrument is used for cleaning, the suction inlet at the bottom of the machine body is contacted with the surface to be cleaned, the rolling brush is arranged at the suction inlet, and the allergy sources such as dust, mites and the like are sucked into the dust cup from the suction inlet through the rolling beating of the rolling brush and the suction force provided by the fan, so that the mite removing and dust removing functions are realized.

Specifically, in one related art, a separate design of the mite-removing instrument cleaning base is used to clean dust in the dust cup. First, a dust outlet is arranged at the bottom of the dust cup, and the dust outlet is connected with a dust collecting base on the base. The dust collection base is internally provided with the dust collection motor, the dust collection motor works to suck the dust outlet cover of the mite removal instrument open, so that dust mites and garbage in the dust cup can be conveniently sucked into the dust bag of the dust collection bin, and the dust cup is cleaned. The technology can realize cleaning of the dust cup without disassembling the dust cup, and is time-saving and labor-saving. But the problem that the dust and dirt of the size particles are easy to accumulate in the gap of the dust cup at the dust outlet cover and are not easy to be sucked by the integrated motor exists, and the whole machine cost of the independent dust collecting base is high.

Based on this, the present invention proposes a dust cup structure to overcome or partially overcome the above-mentioned drawbacks of the related art, and embodiments of the present invention will be described in detail below.

Referring to FIG. 1, there is shown a dirt cup structure provided in accordance with an embodiment of the present invention, the dirt cup structure comprising:

In this embodiment, the separation cup 101 is used for separating air from dust, that is, when the mite breaker is in operation, small particles such as dust, hair, etc. sucked into the separation cup 101 through the air inlet 103 are separated from air by the filter 2, the air is discharged through the air outlet 104, and the small particles such as dust, etc. remain in the filter 2.

The dust collecting cup 102 is used for collecting small particles such as dust, a self-cleaning box 3 is arranged in a groove position of one side of the dust collecting cup 102 close to the air inlet 103, and a filter disc 303 is arranged on one side of the cleaning box 3 close to the dust collecting cup 102.

In practice, the filter 303 may be a HEPA (High-EFFICIENCY PARTICULATE AIR, high efficiency particulate air) filter, which operates on the basis of physical filtration, which is capable of capturing very small particles, including dust, pollen, smoke, bacteria and viruses, even some minimal dust mites and their excretions. HEPA filters are typically composed of randomly arranged fibers, typically between 0.5 and 2.0 microns in diameter. The HEPA filter must be able to capture at least 99.97% of particles with a diameter of 0.3 microns, just in the range that most filter materials can be penetrated.

The motor is rotated in the forward direction, namely a dust collection motor of the mite removal instrument, and the motor in an air suction or blowing mode can be controlled by controlling the motor to rotate in the forward direction or rotate in the reverse direction, namely the air suction mode is adopted when the motor rotates in the forward direction, the motor sucks air from the air outlet 104 to the separation cup 101, and small particles such as dust can be sucked into the separation cup 101 from the air inlet 103 along with air flow; when the motor is reversed, the blowing mode is adopted, and air is blown from the air outlet 104 to the separation cup 101, so that small particles such as dust are sent into the dust collection cup 102.

In practical application, when the mite-killing instrument performs dust collection operation, the forward and reverse rotating motor is in a suction mode, mites, dust, hair or other small particles enter the separation cup 101 through the air inlet 103 along the air flow, and are separated from the air under the action of the filter 2, the air is discharged through the air outlet 104, and the small particles such as dust are left in the filter 2; when the dust cup structure needs to be self-cleaned by the mite removal instrument, the forward and reverse rotating motor is controlled to enter the blowing mode, and the forward and reverse rotating motor blows air to the separation cup 101 from the air outlet 104, so that mites, dust, hair or other small particles attached to the filter 2 enter the dust cup 102 from the separation cup 101, and finally fall onto the filter sheet 303 arranged on one side, close to the dust cup 102, of the self-cleaning box 3. After the self-cleaning mode is completed, the self-cleaning cartridge 3 is taken out with the filter 303, and the filter 303 is replaced.
