If the surface of the heating element is not cleaned for a long time, or if it is not cleaned thoroughly by humans, it will affect the baking effect of the heating element on the cigarette cartridge, thereby affecting the consumer's smoking experience. The cleanliness of the heating element when it is manually cleaned is affected by many factors. Existing mechanical cleaning devices cannot effectively clean curved heating elements. Summary of the invention

[0003] The present invention is proposed to solve at least one of the above problems.

[0004] The first aspect of the present invention provides a cleaning device for curved surface components, the cleaning device comprising: a pressure button 1, a spring 2, a double-axle gear 3, a gear push bar 4, a double-axle bevel gear 6, a first bevel gear 7, and an annular brush 11;

The pressure button 1 can reciprocate with the rotating shaft 13 as a fixed point, and at the same time drive the gear push bar 4 to reciprocate;

[0006] The spring 2 has a fixed point and a movable point, the fixed point is fixed on the cleaning device, and the movable point is arranged in the pressure button 1. When the pressure button 1 reciprocates with the rotating shaft 13 as a fixed point, the spring 2 is compressed and restored;

[0007] The gear push bar 4 is meshed with the small diameter gear of the dual-axle gear 3, and the large diameter gear of the dual-axle gear (3) is meshed with the small diameter gear of the dual-axle bevel gear 6;

[0008] The dual-axle gear 3 and the dual-axle bevel gear 6 are arranged vertically, and the first bevel gear 7 is arranged horizontally. The large-diameter gear of the bevel gear 6 is a bevel gear, and the bevel gear is meshed with the first bevel gear 7;

[0009] The first bevel gear 7 is in transmission connection with the annular brush 11 .

[0010] The fixed point and the movable point of the spring 2 can be the end or the non-end of the spring, as long as the spring can be compressed and rebound when the pressure button 1 is pressed or not pressed.

[0011] The way of connecting the pressure button 1 with the gear push strip 4 can be selected from snap connection, bonding, etc. The lower end of the pressure button 1 can be provided with a notch for inserting the gear push strip 4 to snap the gear push strip 4.

[0012] The annular brush 11 may be directly connected to the rotating shaft of the first bevel gear 7 , or connected to the rotating shaft of the first bevel gear 7 via a connecting rod such as a telescopic rod 8 .

[0013] The hollow structure in the annular brush 11 is used to place the parts to be cleaned.

[0014] After pressing the pressure button 1, the dual-axle gear 3, the dual-axle bevel gear 6, and the first bevel gear 7 are driven to rotate in sequence, thereby driving the annular brush 11 to rotate to clean the parts to be cleaned.

[0015] Preferably, the cleaning device further comprises: a housing 5 , and the dual-axle gear 3 , the gear push bar 4 , the dual-axle bevel gear 6 , and the first bevel gear 7 are all arranged inside the housing 5 .

[0016] The specific structures of the dual-axle gear 3, the dual-axle bevel gear 6 and the first bevel gear 7 are conventional arrangements in the art and will not be described in detail in the present invention.

[0017] Preferably, the cleaning device further comprises:

[0018] a telescopic rod 8, which connects the rotating shaft of the first bevel gear 7 and the annular brush 11;

[0019] The cleaning tube 23 has a thread 9 on its inner wall and the annular brush 11 is arranged in its hollow structure;

[0020] The annular brush 11 comprises: an annular upper base 10, an annular lower base 12, and a brush strip 16 installed between the annular upper base 10 and the annular lower base 12; the outer wall of the annular upper base 10 and / or the annular lower base 12 is provided with an external thread matching the thread 9, the annular brush 11 and the cleaning tube 23 are threadedly connected, and when the annular brush 11 rotates, it can move axially in the cleaning tube 23 by relying on the thread 9. At this time, the telescopic rod 8 undergoes telescopic movement.

[0021] Preferably, a gear pusher slide rail 19 is provided inside the housing 5, which is an arc-shaped cavity structure with two ends open;

[0022] The gear push bar 4 is accommodated in the gear push bar slide rail 19 and limits the gear push bar slide rail 19 to move within the space defined by it.

[0023] Preferably, the pressure button 1 is a regular structure or an irregular structure, and the regular structure is selected from one of a fan-shaped sheet structure, a hemispherical structure, and a columnar structure.

[0024] Preferably, the spring 2 is selected from one of a V-shaped spring sheet, a torsion spring, and a compression spring, one end of the spring 2 is fixed to the cleaning device, and the other end is clamped or abutted against or connected to the pressure button 1.

[0025] Preferably, the telescopic rod 8 is a telescopic rod that cannot rotate freely but can only be telescopic, that is, the sections of the telescopic rod 8 can only move relative to each other in the axial direction and cannot rotate relative to each other. The telescopic rod 8 can only rotate as a whole under the drive of an external force.

[0026] Preferably, the annular upper base 10 and the annular lower base 12 are provided with a plurality of brush insertion holes distributed in a circumferential array, and a plurality of brush strips 16 are installed on the annular upper base 10 and the annular lower base 12 through the brush insertion holes.

[0027] The second aspect of the present invention provides a method for using the cleaning device described in any one of the first aspects, wherein the element to be cleaned is placed in the annular brush 11, and the pressure button 1 is pressed, so that the pressure button 1 rotates with the pressure button rotating shaft 13 as a fixed point, and the pressure button 1 moves toward the inside of the housing 5, and the spring 2 is compressed. At the same time, the pressure button 1 drives the gear push bar 4 to push the small diameter gear in the double-axle gear 3 to rotate, and the large diameter gear of the double-axle gear 3 drives the small diameter gear of the double-axle bevel gear 6 to rotate, and the large diameter gear of the double-axle bevel gear 6 drives the first bevel gear 7 to rotate, and the first bevel gear 7 drives the annular brush 11 to rotate clockwise through the telescopic rod 8. Since the annular brush 11 is threadedly connected to the cleaning tube 23, when the annular brush 11 rotates clockwise, the thread 9 will cause the annular brush 11 to have a tendency to move downward. At this time, the overall motion trajectory of the annular brush 11 is a downward spiral motion. In this process, the annular brush 11 cleans the outer surface of the element to be cleaned;

[0028] After pressing the pressure button 1, release your hand naturally. At this time, the previously compressed spring 2 rebounds, and the spring 2 pushes the pressure button 1 to move away from the shell 5. The pressure button 1 pulls the gear push bar 4 in the direction away from the shell 5, and the gear push bar 4 pulls the small diameter gear in the double-axle gear 3 to rotate, and the large diameter gear of the double-axle gear 3 drives the small diameter gear of the double-axle bevel gear 6 to rotate, and the large diameter gear of the double-axle bevel gear 6 drives the first bevel gear 7 to rotate, and the first bevel gear 7 drives the annular brush 11 to rotate counterclockwise through the telescopic rod 8, and the thread 9 will make the annular brush 11 tend to move upward, and at this time, the movement trajectory of the annular brush 11 is an upward spiral motion; in this process, the annular brush 11 cleans the outer surface of the component to be cleaned.

[0029] The lower end of the telescopic rod 8 is connected to the annular upper base 10 of the annular brush 11, and the connection method can be any suitable detachable connection method such as snap connection, plug connection, thread connection, magnetic connection, etc.

[0030] When the annular brush 11 moves axially in the cleaning tube 23, the telescopic rod 8 extends and contracts.

[0031] Preferably, the gear push bar slide rail 19 is an arc-shaped cavity structure with open ends, and its width is greater than the thickness of the pressure button 1. The gear push bar slide rail 19 provides space for the pressure button 1 and the gear push bar 4 to move.

[0032] Preferably, the pressure button 1 is a fan-shaped sheet structure, the spring 2 is a V-shaped spring sheet, and one end of the V-shaped angle of the V-shaped spring sheet extends in the same direction as the central angle of the fan-shaped sheet structure.

[0033] Preferably, the pressure button 1 is made of a friction-resistant material, and the cross-sectional shape of the pressure button 1 is not limited to a sector shape, but may also be other regular or irregular shapes.

[0034] Preferably, the gear push bar 4 is a component with wear resistance and certain strength. The material can be selected from polyoxymethylene POM, for example.

[0035] The gear push bar 4 can be a rack or any regular or irregular component, as long as its end has a rack meshing with the small-diameter gear in the dual-axle gear 3 .

[0036] The element to be cleaned can be a rod-shaped heating element or a quasi-cylindrical heating element.

[0037] The push-type cleaning device for curved surface elements of the present invention is particularly suitable for central heating smoking articles, wherein the heating element is a rod-shaped heating element or a cylindrical heating element, and the heating element is arranged at the center of the heating cavity.

[0038] When used together, it is required that the outer diameter of the cleaning tube 23 is smaller than the inner diameter of the heating chamber, and the diameter of the hollow cavity of the annular brush 11 is larger than the outer diameter of the heating element.

[0039] When the heating element needs to be cleaned, hold the shell 5 of the cleaning device by hand, press the pressure button 1 with your finger, and extend the cleaning tube 23 as a whole into the heating chamber of the smoking device, so that the heating element to be cleaned is wrapped in the annular brush 11, and the outer wall of the cleaning tube 23 of the device contacts the inner surface of the cigarette cup or there is a gap between the outer wall of the cleaning tube 23 of the device and the inner surface of the cigarette cup.

[0040] The above technical solutions can be freely combined under the premise of no contradiction.

[0041] The present invention has the following beneficial effects:

[0042] 1. The present invention provides a push-type cleaning device for curved surface components for the first time. When the pressure button 1 is pressed and reset, the force in the left and right directions is converted into the force of the first bevel gear 7 to rotate by the double-axle gear 3 and the double-axle bevel gear 6, and then drives the annular brush 11 to rotate to achieve the purpose of cleaning. The push-type operation is simple and the cleaning efficiency is high, avoiding the defect of incomplete cleaning by simple manual cleaning.

[0043] 2. The present invention can realize the self-rotation of the annular brush 11 by manual pressing and spring cooperation, avoiding the use of a motor as a power source, saving energy, and the device is light and easy to carry without replacing batteries or using a power cord.

[0044] 3. In the preferred technical solution, the annular brush 11 of the present invention is arranged in a cleaning tube 23 having a thread 3 on the inner wall, and is connected to the first bevel gear 7 through a telescopic rod, and the first bevel gear 7 drives the annular brush 11 to perform an upward or downward spiral motion. Compared with the brush 11 that simply performs a rotational motion at the same height, the brush 11 that performs an upward and downward spiral motion has a more thorough cleaning effect.

[0045] 4. The cleaning device of the present invention is easy to use. You only need to hold the outer shell 5 of the cleaning device, press the pressure button 1 with your finger, extend the cleaning tube 23 as a whole into the heating chamber of the smoking device, so that the heating element to be cleaned is wrapped in the annular brush 11, and then repeatedly press the pressure button 1. Deep cleaning can be achieved without disassembling the heating element.

[0046] 5. In the cleaning device of the present invention, the annular brush 11 is arranged in the cleaning tube 23, and the brush is not exposed, which can protect the brush, prevent the brush strip from falling, and extend the service life of the brush. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The spring 2 is a V-shaped spring sheet. The gear push bar 4 is a rack. The pressure button 1 is a fan-shaped sheet structure, and one end of the central angle is the upper end.

[0058] Figure 1 The overall schematic diagram of the curved surface element cleaning device in Example 1, the gear push bar slide rail 19 is an arc-shaped cavity structure matching the lower end surface of the pressure button 1, and the two ends are open. When the pressure button 1 is pressed, a part of it can move in the gear push bar slide rail 19. The left end of the gear push bar 4 is connected to the right end of the pressure button 1, and the right end of the gear push bar 4 is meshed with the small diameter gear of the double-axle gear (3). The gear push bar 4 is arc-shaped and can move in the space defined by the gear push bar slide rail 19.

[0059] like Figure 2 As shown, the positional relationship between the pressure button 1 and other parts of the embodiment 1 of the present invention is as follows:

[0060] The pressure button rotation shaft 13 is disposed at the upper end of the pressure button 1 and is used to fix the upper end of the pressure button 1 on the housing 5 .

[0061] The spring fixing pin 14 is used to fix the middle position of the V-shaped spring sheet. The left end of the V-shaped spring sheet abuts against the inner wall of the pressure button 1, and the right end passes through the pressure button 1 and is fixed on the housing 5. The V-shaped spring sheet provides support force for the pressure button 1. In this embodiment, the left side wall of the pressure button 1 is closed to provide a pressure surface when pressed, and the right side of the pressure button 1 can be open and not set on the side wall to provide a channel for the V-shaped spring sheet to pass through.

[0062] like Figure 3 and Figure 4 The figure shows a top view and a front view of the annular brush 11 in the present embodiment 1. The annular brush 11 is composed of a brush strip 16, an annular upper base 10 and an annular lower base 12.

[0063] One side of the brush strip 16 has bristles, and the side with the bristles is located on the inner side of the annular brush 11 during installation.

[0064] like Figure 5 The figure shows a part of the internal structure of the cleaning device housing 5 in this embodiment 1. The housing 5 is provided with a double-coupled gear fixing shaft 17 for fixing the double-coupled gear 3, a double-coupled bevel gear fixing shaft 18 for fixing the double-coupled bevel gear 6, a gear push bar slide rail 19 for allowing the gear push bar 4 to slide according to a preset trajectory, and a telescopic rod upper end fixing point 20 and a telescopic rod lower end fixing point 21 for fixing the telescopic rod 8.

[0065] The cleaning tube 23 is detachably mounted below the housing 5, and the cleaning device cavity 22 therein is used to mount the annular brush 11 and accommodate the components to be cleaned.

[0066] The working process of a cleaning device for a curved surface component in this embodiment 1 is as follows:

[0067] When the pressure button 1 is pressed, the pressure button 1 rotates into the housing 5 with the pressure button rotating shaft 13 as the fixed point, and at the same time drives the gear push bar 4 to move. At this time, the V-shaped spring is compressed, and the whole pressing process has a certain resistance. The gear push bar 4 drives the small diameter gear in the double-axle gear 3 to rotate counterclockwise, and the large diameter gear of the double-axle gear 3 rotates counterclockwise and drives the small diameter gear of the double-axle bevel gear 6 to rotate clockwise. The large diameter gear of the double-axle bevel gear 6 drives the first bevel gear 7 to rotate horizontally clockwise clockwise, and the first bevel gear 7 drives the annular brush 11 through the telescopic rod 8 to make a downward spiral motion in the cleaning tube 23 as the overall motion trajectory. The telescopic rod 8 is stretched at the same time, and the annular brush 11 starts to clean the parts to be cleaned;

[0068] After pressing the pressure button 1, release your hand naturally. At this time, the previously compressed V-shaped spring sheet rebounds, pushing the pressure button 1 to move away from the housing 5 with the pressure button rotating shaft 13 as the fixed point. The pressure button 1 pulls the gear push bar 4 to the left, and the gear push bar 4 pulls the small diameter gear in the double-axle gear 3 to rotate clockwise. The large diameter gear of the double-axle gear 3 rotates clockwise and drives the small diameter gear of the double-axle bevel gear 6 to rotate counterclockwise. The large diameter gear of the double-axle bevel gear 6 rotates counterclockwise and drives the first bevel gear 7 to rotate counterclockwise. The first bevel gear 7 drives the annular brush 11 through the telescopic rod 8 to make an upward spiral motion in the cleaning tube 23. The telescopic rod 8 is shortened at the same time, and the annular brush 11 starts to clean the parts to be cleaned.

[0069] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
