Description

[Technical field]

[0001] This invention relates to a vacuum cleaner that has an air purifying function by using an airborne dust collector. [Background technology]

[0002] Conventionally, electric vacuum cleaners with air purification functions have been known. For example, there is a device that sucks in exhaust air from the vacuum cleaner body through the air purifier's intake port, purifies fine dust contained in the exhaust air from the vacuum cleaner body, and discharges it, thereby preventing dust from scattering in the room. This device is an air purifier necessary for cleaning the exhaust air of the vacuum cleaner, and does not function as an air purifier for the air in the entire room. On the other hand, there is a device that is provided with an electric blower used to function as an electric vacuum cleaner, and an electric motor with a purifier fan used to function as an air purifier, inside the vacuum cleaner body. In this device, a dust collection filter and a cleaning filter are provided separately. Such a device has a problem that the device itself is large and heavy, making it difficult to carry around easily, and lacking in convenience.

[0003] Generally, two devices are used: a vacuum cleaner and an air purifier. That is, the dust that falls on the floor is collected by the vacuum cleaner, and the dust floating in the air is collected by the air purifier. The air purifier works to reduce the dust that has risen into the air. In particular, air purifiers equipped with HEPA filters can remove fine particles (PM2.5 level) and capture dust, dead mites, pet hair, etc. By creating air flow, the air is circulated throughout the room, which is expected to have a certain effect in preventing dust from rising again. Air purifiers also have the added function of sterilizing with ultraviolet rays, etc. Therefore, both vacuum cleaners and air purifiers are necessary to keep a room clean.

[0004] However, there was no small, lightweight, and inexpensive device that combined the functions of both a vacuum cleaner and an air purifier, so there was a problem that people had to purchase two devices: a vacuum cleaner and an air purifier.

[0005] As a measure to improve this problem, a method is proposed in which the above-mentioned air purifier function is easily added to a vacuum cleaner that captures dust and the like that has accumulated on floors, desks, and shelves. In recent years, vacuum cleaners have become more compact and sophisticated, becoming lighter and more absorbent, and the number of models equipped with HEPA filters is increasing, making it possible to remove fine particles, pollen, etc. This is an attempt to add the function of an air purifier to such vacuum cleaners. In other words, the vacuum cleaner captures dust suspended in the air before it falls onto the floor, desk, or shelf. To do this, the dust intake port is held high in the air and the vacuum cleaner is operated. It has become clear that this makes it easy to capture dust with the powerful suction power of the vacuum cleaner. Dust that has accumulated on the floor can be cleaned with a floor cleaning head, and then the head is replaced with the head of this invention that captures dust in the air. It also purifies the air, making the room cleaner. A filter is a type of air filter used to remove dirt, dust, etc. from the air to make it clean. It is used in air purifiers and air filters. JIS Z 8122 specifies that an air filter has a particle collection rate of 99.97% or more for particles with a diameter of 0.3 μm at the rated air volume, and an initial pressure loss of 245 Pa or less.

[0007] [Non-Patent Document 1] Wikipedia, the free encyclopedia Summary of the Invention [Problem to be solved by the invention]

[0008] The problems to be solved are the shape of the dust suction part used in the head of the vacuum cleaner to collect dust in the air, the shape of the dust suction port, and how to connect and integrate the dust suction part with the vacuum cleaner. [Means for solving the problem]

[0009] The dust suction part of this device is cylindrical or hollow polygonal prism shaped, and has many slit-shaped holes on the periphery of the cylinder to serve as dust suction ports. The dust suction part is connected to the suction tube of a vacuum cleaner. The main feature of this device is that the dust suction part is arranged vertically and used to suck in dust in the air. Effect of the Invention

[0010] The handheld stick vacuum cleaner with the air purifier function of this invention is small and lightweight, making it easy to carry to each room in the house and highly convenient. In particular, if the stick vacuum cleaner with the integrated dust suction unit is placed on a dolly together with the support base and made movable, it has the advantage of being able to be used as a self-propelled air purifier. [Brief description of the drawings]

[0011] [Figure 1] FIG. 1 is a diagram showing how to implement a handy stick vacuum cleaner with the function of an air cleaner according to the present invention. (Example 1) [Diagram 2] FIG. 2 is a diagram showing the shape of the dust suction part of the present invention. (Example 2) [Diagram 3] FIG. 3 is a diagram showing the shape of the support base of the present invention. (Example 3) [Figure 4] FIG. 4 is a diagram showing the shape of the moving cart of the present invention. (Embodiment 4) [Diagram 5] FIG. 5 is a diagram showing the arrangement of the present invention when collecting dust at a low position. (Example 5) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The goal of making a vacuum cleaner with added air purifying functions smaller and lighter so that it would be easier to use on a daily basis has been achieved in a very simple way using inexpensive parts. EXAMPLES

[0013] FIG. 1 is a diagram of one embodiment of the device of the present invention, in which 1 is a dust suction part, 2 is a dust suction hole, 3 is a stick type vacuum cleaner, and 4 is a connection part.

[0014] The dust suction part 1 is cylindrical and made of PET with a thickness of 0.25 mm, with a diameter of 7 cm and a length of 40 cm. The dust suction part 1 has a dust suction hole 2, which is 3 mm wide and 40 mm long, with 16 holes on the peripheral side of the cylinder. Therefore, the dust floating in the air around the dust suction part 1 is quickly collected by the suction force of the vacuum cleaner 3. By attaching an extension suction tube to the suction tube of the vacuum cleaner 3, the dust suction part 1 can be raised to a height close to the ceiling. In addition, by increasing the length of the dust suction part 1, dust from a wider area can be collected. The shape of the dust suction part 1 may be a polygonal column or the like as long as it is hollow. The material may be plastic such as PP, PE, polycarbonate, acrylic, or metal such as aluminum, copper, stainless steel, paper, wood, etc. The vacuum cleaner 3 is a cordless stick vacuum cleaner with a HEPA filter. EXAMPLES

[0015] 2 shows another shape of the dust suction unit 1 of the present invention. The dust suction unit 1 is in the shape of a hollow rectangular prism and the dust suction holes 2 are in the shape of a circle, but they may also be elliptical, rectangular, etc. Regarding the shape and arrangement of the dust suction holes, if elongated elliptical holes are arranged vertically, the dust collection area in the height direction will be expanded. EXAMPLES

[0016] Figure 3 shows the shape of the support stand 5. It vertically holds the vacuum cleaner 3 with the dust suction unit 1 on its head. It is used to collect dust suspended in the air. A plastic support stand 5 was used, but it could also be made of aluminum, wood, etc. The vacuum cleaner with integrated dust suction unit could be easily moved to the desired location while still fixed to the support stand. EXAMPLES

[0017] Fig. 4 is a diagram showing the shape of the movable dolly 6. By placing the above-mentioned dust suction unit integrated vacuum cleaner fixed to the support base 5 on the movable dolly 6, not only can it be moved from place to place more easily, but also it can be made into a self-propelled air cleaner by setting a route within a room. EXAMPLES

[0018] FIG. 5 shows a method of lowering and locating the dust suction unit 1 in order to collect dust suspended in the air at a low position, i.e., close to the floor height. [Industrial Applicability]

[0019] If the dust suction part of this invention is used in a small stick-type vacuum cleaner, it can be used as a self-propelled air purifier, and can be used not only as an air purifier for a room, but also as an air purifier for a large hall. [Explanation of symbols]
