Description

Technical Field

[0001] This utility model relates to the field of vacuuming technology, and in particular to a vacuuming tube with a porous structure. Background Technology

[0002] Vacuum cleaners can be classified into upright, canister, and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, creating negative air pressure in the sealed shell to suck up dust and debris. The structure of a vacuum cleaner mainly includes the power unit, filtration system, functional parts, hose, and suction head. Depending on the usage scenario, suction heads have different structures such as floor brush type, cylindrical type, and blade type. However, the characteristics of existing suction heads are that they are too large or have a large suction diameter, which cannot suck up dust in some dead corners or narrow gaps, thus limiting their use.

[0003] Therefore, it is necessary to solve the above problems by proposing a porous dust suction tube. Utility Model Content

[0004] The purpose of this invention is to provide a porous dust collection tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a porous dust collection tube, comprising:

[0006] straw holder;

[0007] The straws are provided in multiples, with both ends of each straw being open and serving as an input end and an output end, respectively. The output ends of the multiple straws pass through the straw support and are fixed to the straw support.

[0008] Preferably, the straw holder has a sleeve-like structure, with one end open and the other sealed. The sealed end of the straw holder has several through holes, and the output ends of multiple straws are inserted into the sealed end of the straw holder and the several through holes, extending into the straw holder.

[0009] Preferably, it also includes epoxy resin, which fills the gap between the inner side of the straw holder and the plurality of straws to fix the plurality of straws.

[0010] Preferably, the inner wall of the straw is smooth, the outer diameter of the straw is 2.5-3.5 mm, and the inner diameter is 1.8-3.0 mm.

[0011] Preferably, the input end of the straw has a constricted end and is integral with the straw, and the inner diameter of the constricted end is smaller than the inner diameter of the straw.

[0012] Preferably, the straw is made of PP or PA plastic.

[0013] Preferably, it also includes a sheath that is placed over the outside of the multiple straws to hold the multiple straws together.

[0014] Preferably, it also includes a connector, both ends of which are open, the straw holder is sealed to one open end of the connector, and the straw is located outside the connector.

[0015] Preferably, the end of the connector away from the straw holder is connected to a multi-purpose connector.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. The structure of this utility model is applicable to commercial, household, portable, and vehicle-mounted vacuum cleaners, and has a wide range of applications.

[0018] 2. This utility model vacuum cleaner fitting is assembled from multiple small-diameter suction tubes. Depending on the size of the vacuuming area, one or more suction tubes can be used selectively to solve the problem of dust in dead corners or crevices that cannot be reached by vacuum cleaners on the market. At the same time, the combination of multiple suction tubes has a good coverage area and ensures vacuuming efficiency. Because the vacuum cleaner fitting uses multiple suction tubes to suck up dust, and the suction tube diameter is small, it is not necessary to remove the object before vacuuming, making it convenient and quick to use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Example 1:

[0034] like Figure 1-5As shown, a multi-hole vacuum cleaner fitting is provided, including a suction tube bracket 1 and suction tubes 2. The number of suction tubes 2 is set to multiple, and both ends of the suction tubes 2 are open and are respectively the input end and the output end. The output ends of the multiple suction tubes 2 pass through the suction tube bracket 1 and are fixedly connected to the suction tube bracket 1. The multiple suction tubes 2 are arranged together and the ends are fixed by the suction tube bracket 1 to form an integral structure. This structure is suitable for commercial, household, portable and vehicle vacuum cleaners, and is installed at the input end of the vacuum cleaner as the suction end.

[0035] This embodiment further specifies that: the straw 2 has a cylindrical tubular structure, the inner wall of the straw 2 has a smooth surface, and the straw 2 is made of PP or PA plastic by extrusion molding. The outer diameter of the straw 2 is 2.5-3.5mm, the inner diameter is 1.8-3.0mm, and the aperture of the straw 2 can be adjusted within the range as required.

[0036] Because the suction tube 2 is made of PP or PA plastic and has a small diameter, pressure can be applied manually to bend it during use, allowing it to pick up dust from crevices, corners, or hard-to-reach areas that ordinary vacuum cleaners cannot reach. Depending on the size of the gap, one or more suction tubes 2 can be used for vacuuming. Due to the small diameter of the suction tube 2, it is not necessary to move items before vacuuming. For example, when cleaning dust in a drawer, it is not necessary to move the daily necessities inside the drawer, avoiding the situation where a large nozzle of a conventional vacuum cleaner might suck a lot of daily necessities into the trash can.

[0037] like Figure 5 As shown, this embodiment further specifies that: the input end of the straw 2 is provided with a constriction 4. The preparation process of the constriction 4 is to apply pressure and heat it by a jig when cutting the input end of the straw 2, so that the input end of the straw 2 is reduced and then cut to form the constriction 4 structure. The inner diameter of the end of the constriction 4 is smaller than the inner diameter of the straw 2. During use, it filters out dust and garbage with a width greater than the inner diameter of the straw 2, preventing garbage from clogging the inside of the straw 2 and causing the straw 2 to become blocked.

[0038] like Figure 1 and 2 As shown, this embodiment further includes a sheath 3, which is used to cover the outside of multiple straws 2 to concentrate the multiple straws 2 and prevent the straws 2 from bending due to excessive pressure during use. In specific use, by moving the sheath 3 along the length of the straws 2 or removing the sheath 3, the sheath 3 can be adjusted to a suitable position to concentrate the multiple straws 2, or the concentration of multiple straws 2 can be canceled when a single or a small number of straws 2 are in use, making it easy to bend the straws 2 to a suitable angle, and it has a wide range of applications.

[0039] like Figure 2 and 4As shown, this embodiment further specifies the following: The straw 2 and straw holder 1 are fixed in a sleeve-like structure, with one end open and the other sealed. The sealed end of the straw holder 1 has several through holes 5. The output ends of multiple straws 2 are inserted into the sealed end of the straw holder 1 and into the several through holes 5, extending into the straw holder 1. In actual production, the inserted and extended straws 2 protrude beyond the open end of the straw holder 1. There are gaps between the inner side of the straw holder 1 and the multiple straws 2, and between the multiple straws 2 themselves. These gaps are filled with epoxy resin 7 adhesive, but the epoxy resin 7 does not... The open end of the overflow straw holder 1 is used to fix multiple straws 2 and the straw holder 1. The straw 2 is inserted and extended beyond the open end of the straw holder 1, which facilitates the pouring of epoxy resin 7 and avoids the epoxy resin 7 entering the straw 2 and causing blockage of the inner hole of the straw 2. After the epoxy resin 7 is poured and cured, the straw 2 protruding beyond the open end of the straw holder 1 is cut off, keeping the output end of the straw 2 flush with the open end of the straw holder 1, so as to ensure the neatness and aesthetics of the straw 2 installation. The straw 2 adopts the structure design of insertion and glue fixation, which reduces the processing difficulty of the straw holder 1 and multiple straws 2 being integrally molded.

[0040] Example 2: Further limitations based on the content of Example 1.

[0041] like Figure 4 , 6 As shown in Figure 9, it also includes a connector 8, which is a hollow structure. The connector 8 has two ends, both of which are open. The two ends are the input end and the output end, respectively. The suction tube bracket 1 is sealed to the input end of the connector 8, and the suction tube 2 is located outside the connector 8. The connector 8 is a transfer connection component between the structure of Embodiment 1 and the vacuum cleaner.

[0042] This embodiment further defines the installation method of the structure and connector 8 in Embodiment 1;

[0043] like Figure 8 As shown, the input end of the straw 2 is inserted into the connector 8 from the output end of the connector 8 and exits from the input end of the connector 8. The outermost straw 2 of the multiple straws 2 is fitted to the inner side wall of the open input end of the connector 8. The inner cavity space of the connector 8 and the inner diameter of the output end are larger than the inner diameter of the input end of the connector 8, so that the straw support 1 can be inserted into the interior of the connector 8 and the straw support 1 can be confined inside the connector 8.

[0044] like Figure 4 and 8As shown, the outer wall of the open end of the straw support 1 is provided with an extended edge 6. The extended edge 6 and the straw support 1 are an integral structure. The outer side of the extended edge 6 is fitted with the inner wall of the connector 8 to ensure the stability of the straw support 1 after installation. The straw support 1 can be detached or fixedly installed in the inner cavity of the connector 8 by means of snap-fit, ultrasound, glue, etc.

[0045] like Figure 9 As shown, this embodiment further specifies that: the output end of the connector 8 is plugged into a multi-purpose connector 9, the shape of the multi-purpose connector 9 is not limited, and different shapes of multi-purpose connector 9 can be replaced to adapt to various vacuum cleaners on the market. The multi-purpose connector 9 serves as a transfer connector to install the vacuum tube fitting of this application at the vacuum cleaner's vacuum input end.

[0046] like Figure 9 As shown, this embodiment further specifies that: an exhaust hole 10 is provided on the side wall of the connector 8, the exhaust hole 10 is an elongated through hole, and a suction regulating valve 11 is rotatably installed on the outside of the side wall of the connector 8. The suction regulating valve 11 has a semi-ring structure and is used to cover the exhaust hole 10. The rotatable installation of the suction regulating valve 11 includes, but is not limited to, using a bearing for rotatable installation and a limited placement for rotation. Rotating the suction regulating valve 11 adjusts the coverage area of ​​the exhaust hole 10 to achieve the adjustment of the suction power during dust collection. The increase in the area of ​​the exhaust hole 10 covered by the suction regulating valve 11 enhances the dust collection suction power.

[0047] This embodiment further specifies that: the exhaust port 10 is provided with a dust-blocking structure, which includes, but is not limited to, using a dust-blocking mesh, to ensure air permeability while preventing dust from being discharged from the exhaust port 10.

[0048] It should be noted that all components in Examples 1 and 2 are made of insulating materials, such as plastic, to avoid the risk of electric shock.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
