Description

Household washing machine

Technical field

The present invention relates to an apparatus for home cleaning using a water line having a certain pressure.

Background technique

Daily cleaning of your teeth and improper brushing can damage your enamel and even your dentin. Using a water line with a certain pressure to rinse the teeth is more conducive to protecting the teeth and gums.

At present, some household cleaning devices have not been able to solve some fundamental problems: for example, the water is flushed into the cavity, but the oral cavity cannot be exported in time, which makes the washing process have to be interrupted frequently, and finally has to give up; the pressurized water rushes to the tooth surface. The water will splash out of the mouth, the greater the water line pressure, the more splashing the water, the water line has no pressure, and there is no effect, meaningless; by turning the handle of the arm, the up and down direction of the water line can be adjusted, but the left and right adjustment There is no way to wait (the teeth are curved). The present invention solves the above problems, and enables the cleaning device to be practically used in people's daily life.

Summary of the invention

The current household cleaning device is mainly composed of a water storage tank, a motor and a handle. The present invention relates to the following components of the dental cleaning device: a water storage tank A, a handle C, a backflow cover D, a spray head E, an adjustable nozzle F, Small obstruction leaf G, large obstruction leaf Y. The dotted line box of B in Fig. 1 indicates the motor portion (the so-called motor is a micro pump), and the present invention does not relate to this portion.

Water storage tank A: The water storage tank A is a closed device for storing fresh water and gray water. FIG. 1 is a schematic illustration of a spherical glass tank. The water storage tank A has a fresh water chamber X and a gray water chamber H, and the fresh water chamber X has a fresh water inlet (1) with a sealing cover (5), and a fresh water outlet (2) connected to the motor B; The chamber H has a grey water inlet (3) connected to the gray water pipe (7) and a grey water outlet (4) with a sealing cover (5).

In order to realize the X volume reduction of the fresh water chamber, the volume of the gray water chamber H is equally increased, thereby forming a negative pressure, and the fresh water chamber X outputs fresh water to the oral cavity, and the gray water chamber H automatically recovers the gray water from the oral cavity by the following methods:

a, the water storage tank A is divided into two by the impervious soft film along the inner wall;

b. Use a soft impervious inner bag to be placed in the water storage tank A. The inner bag has the same capacity as the water storage tank. The inner bag has a fresh water inlet, a fresh water outlet, and a corresponding set of the water storage tank A; The bag has gray water inlet, and the gray water outlet is the same;

c, the piston method, as shown in Figure 2 is simple.

Figure 1 shows an example of a water-impermeable flexible film (9). The water-impermeable flexible film (9) can be opened so that the capacity of any one cavity is equivalent to the total capacity of the water storage tank A. The fresh water of the water storage tank A is taken out by the motor B, and reaches the handle through the fresh water pipe (6); the end of the gray water pipe (7) connected to the gray water inlet (3) reaches the mouth.

When using, first fill the fresh water through the fresh water inlet (1) and cover the sealing cover (5); the grey water outlet (4) is also covered with the sealing cover (5). At this time, the fresh water chamber of the water storage tank A has water, and the gray water chamber has no water. When the tooth cleaner is working, the motor draws fresh water, the volume of the fresh water chamber X is reduced, and the gray water chamber H forms a negative pressure, and the gray water is sucked into the gray water chamber H along the gray water pipe (7). In this way, fresh water enters the oral cavity, and the gray water is automatically discharged into the oral cavity, and at the same time, work is performed in equal amounts.

The fresh water inlet (1) and the fresh water outlet (2) of the water storage tank A may also be combined into a fresh water inlet (46), and the grey water inlet (3) and the grey water outlet (4) are combined into a gray water outlet ( 49), and each is equipped with a perforated cover (47), as shown in FIG. Motor B has two glass cannulas (48) that can be inserted into the perforated cover (47). The glass cannula (48) is connected to the motor B and the grey water pipe (7), respectively. A part of the motor B and the gray water pipe (7) are enclosed in a box P, so that the separation of the water tank A and the box P can be realized, and the cleaning of the water tank A and the replacement of the parts can be facilitated. The method of dividing the fresh water chamber X and the gray water chamber H of the water storage tank A is as follows.

Handle C: The handle is an important part of the tooth cleaner, and fresh water is delivered to the mouth through the handle. The conventional handle has a built-in fresh water pipe (6) from the motor B connected to the spray head, or an electric level/wire (8), and a switch, etc. The handle C of the present invention also has a gray water pipe (7) built therein. The gray water pipe (7) protrudes from the inlet end of the handle C, the end of the gray water pipe (7) is sleeved with a hollow head (10), and the vertical head (10) is made of stainless steel or other heavier food grade materials to ensure the gray water pipe (7) Always hang down. There is a connector at the fresh water outlet of the handle C for mounting the nozzle E. This description uses an internal screw as an example. The handle C is shown in Figure 3.

Reflux D: The current cleaning device has no backflow hood, and the backflow hood is an important invention. The flow hood D is placed on the nozzle E of the handle and enters the mouth with the nozzle E. The purpose is to prevent the splash from splashing out of the mouth and collect the water to return it to the mouth. The flow hood D can have various shapes, as shown in Fig. 4, D1 bowl/cup shape, D1-1 horn shape, D1-2, D1-3 are the mixture of the above two, or other similar variant shapes, by comparison Made from soft food grade materials such as silicone or other safe, non-injury materials. This description is illustrated by a bowl/cup shape. The diameter of the opening of the reflector refers to the length of the upper and lower crowns, and the height refers to the brush height of the toothbrush.

The first embodiment of the flow hood D: a loop of soft hair (13) is implanted in the backflow hood to meet the needs of different users, as shown by D2 of FIG. The cover of the backflow cover D2 can be made of both soft and hard materials.

The second embodiment of the flow hood D, that is, the wide-mouth edge returning hood: in addition to the splash-proof cover, the outer flow hose (15) and the handle C cooperate with the nozzle to assist in adjusting the direction of the waterline. The mouthpiece of the backflow hood D3 is slightly thicker and has a thickness of 2 to 4 mm, as shown by D3 in Fig. 4, to increase the adhesion. When in use, the backflow cover D3 touches the teeth or gums, and then drags, pushes, or shifts the handle up and down to achieve the spray direction of the water line on the left and right, so as to truly leave no dead ends.

The third embodiment of the flow hood D, that is, the variant D4 of the reflux cover D, the cover body (11) is relatively short, the height is 6 to 12 mm, the mouth opening is relatively convergent, and the diameter is the height of one crown, which is 6 to 12mm. As shown in D4 of Figure 4. The main function of the reflector is not to prevent splashing, but to assist in adjusting the direction of the waterline. When cleaning the inner edge of the upper and lower jaws, the nozzle is outward from the inside of the mouth, and the backflow of the backflow hood D is meaningless. The nozzle equipped with such a reflux cover is an internal nozzle.

The fourth embodiment of the flow hood D, that is, the backflow hood having the hood: in order to prevent the backflow hood D from being inverted by the wind, the backflow hood is provided with a cover (T-11), or at the same time There are inner cover (T-12) and outer cover (T-11), as shown in D5 and D5-1 of Fig. 4.
