Description

Technical Field

[0001] The utility model relates to a vacuum cleaner, in particular to a portable vacuum cleaner with a front-end green light dust display function. A green light emitting mechanism is arranged at the front end of the portable vacuum cleaner to clearly display dust and hair to be cleaned. Background Art

[0002] With the acceleration of the modern life rhythm, people have higher and higher requirements for the cleanliness and tidiness of home environment, office environment and vehicle interior environment, etc. As a common household appliance, the vacuum cleaner has become an indispensable tool for the daily cleaning of many families. There is a portable vacuum cleaner on the market. After being charged, the user can hold the vacuum cleaner to perform the vacuuming operation, which is not only not restricted by wires, but also light, easy to use and occupies little space, and is especially suitable for vacuuming and cleaning in vehicles, offices, desktop cabinets, etc.

[0003] When the traditional vacuum cleaner is working, the user often cannot intuitively see the cleaning effect of fine particles such as dust and hair. This not only affects the cleaning efficiency, but also makes it difficult for the user to judge whether further cleaning is needed. Therefore, in the prior art, a lighting device is arranged on the vacuum cleaner to display the dust and hair on the surface to be cleaned.

[0004] For example, the utility model patent with the authorization announcement number CN212281196U discloses a vehicle-mounted vacuum cleaner that can emit fragrance. A lighting lamp is installed on one side of the connection between the handle and the housing, and both the lighting lamp and the vacuum cleaner main body are controlled by a switch.

[0005] However, since the lighting lamp is arranged at the connection between the handle and the housing and is relatively close to the switch, when the user vacuums, the user needs to hold the handle and press the switch to keep the vacuum cleaner in the on-vacuuming mode, which makes it easy for the user's hand to block the lighting lamp, bringing inconvenience to the vacuuming operation.

Detailed implementation manners

[0079] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0080] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. The terms "first" and "second" are only for descriptive convenience and have no other directional meaning, and should not be construed as a limitation to the present invention.

[0081] As Figures 1 to 6 The portable vacuum cleaner 100 with a front-end green light dust display function provided in this embodiment includes a handheld part 10 and a dust suction part 20. Among them, the dust suction part 20 includes a dust storage part 21 located at the front end and a power part 22 located at the rear end, and the upper end of the handheld part 10 is connected to the power part 22.

[0082] In this embodiment, the upper end of the handheld part 10 is connected to the rear position on the lower side of the power part 22, and forms an obtuse angle with the power part 22, so that it is more comfortable for the user to hold the handheld part 10 during the dust suction operation, and the dust suction range is easier to expand. Of course, in other embodiments, the upper end of the handheld part 10 can be connected to the middle position on the lower side of the power part, or can be connected to the power part 22 at a right angle.

[0083] A detachable connection is formed between the front end of the power part 22 and the rear end of the dust storage part 21. In this embodiment, the handheld part 10 and the power part 22 have a first housing 31, and the dust storage part 21 has a second housing 32. A detachable connection is formed between the front end of the first housing 31 and the rear end of the second housing 31. The detachable connection method can be circumferential screwing connection, axial snap connection, or radial interference connection; the circumferential screwing connection can adopt a threaded screwing structure, a snap-in slot screwing structure, etc. Thus, during the dust suction operation, the dust storage part 21 is installed at the front end of the power part 22, and dust, hair, etc. will be stored in the second housing 32 of the dust storage part 21; after the dust suction operation is completed, the dust storage part 21 can be detached, and the dust, hair, etc. in the second housing 32 can be poured out and cleaned.

[0084] As Figure 6 shown, a first air inlet j1 is provided at the front end of the power part 22, a first air outlet c1 is provided at the rear end of the power part 22, and a fan assembly 40 is provided inside the power part 22. When the fan assembly 40 is started, it is used to make the air flow enter from the first air inlet j1 and be sent out from the first air outlet c1. A second air inlet j2 is provided at the front end of the dust storage part 21, and a second air outlet c2 is provided at the rear end of the dust storage part 21.

[0085] When the front end of the power part 22 is connected to the rear end of the dust storage part 21, the front end of the first housing 31 is connected to the rear end of the second housing 32, and the second air outlet c2 is docked with the first air inlet j1. Therefore, when the fan assembly 40 is started, the air flow path is the second air inlet j2 - the second air outlet c2 - the first air inlet j1 - the first air outlet c1. During the dust suction operation, the air flow first enters the dust storage part 21 to isolate and store dust, hair, etc. in the second housing 32 of the dust storage part 21.

[0086] As Figures 1 to 4 shown, a green light emitting mechanism 50 is provided at the front end of the power part 22 for emitting green light forward. The front end face of the green light emitting mechanism 50 does not exceed the front end face of the power part 22. The green light emitting mechanism 50 emits green light forward to make the dust and hair to be cleaned on the surface to be cleaned appear, so that it is convenient for the user to perform efficient dust suction operation along the dust and hair to be cleaned that appear, and it is convenient for the user to judge whether the surface to be cleaned has been cleaned. The advantage of using green light is that the dust showing function of green light is clearer and has higher resolution than that of other colors of light.

[0087] Meanwhile, the green light emitting mechanism 50 is disposed on the power unit 22 instead of the handheld unit 10. When the user holds the handheld unit 10 and operates the switch button, it is not easy to touch, grasp or block the green light emitting mechanism 50, so as to ensure that the green light can always be normally emitted forward and does not hinder the user's hand holding and the operation of controlling the switch. In addition, the green light emitting mechanism 50 is disposed on the front end face of the power unit 22, which can not only make space for the user's hand, but also be closer to the surface to be cleaned in front, and the dust display effect is more obvious; the design that its front end face does not exceed the front end face of the power unit 22 can prevent the installation and disassembly of the dust storage unit 21 relative to the power unit 22 from being hindered, and the green light is not easily blocked by the dust storage unit 21.

[0088] As Figure 1 , Figure 3 and Figure 4 shown, the green light emitting mechanism 50 includes a third housing 33, a green light generator 51 disposed in the third housing 33, and a light transmissive surface 52 disposed at the front end of the third housing 33. The green light generator 51 is used to generate dust-displaying green light and emit it from the light transmissive surface 52.

[0089] The third housing 33 is integrally formed by protruding downward from the first housing 31, and the light transmissive surface 52 does not exceed the front end face of the power unit 22. In this embodiment, the light transmissive surface 52 does not exceed the front end face of the first housing 31. There is a distance between the rear end face of the third housing 33 and the handheld unit 22 to form an avoidance space b. The setting of the avoidance space b further makes enough space for the user to hold the handheld unit 10, which not only avoids the hand blocking the green light, but also enables the user's hand holding operation to be more comfortable and unobstructed.

[0090] It should be noted that in this embodiment, the first housing 31 is integral and non-separable in the up and down direction, so that the integrity of the power unit 22 and the handheld unit 10 is better and the appearance smoothness is better. The third housing 33 is integrally formed by protruding downward from the first housing 31, which further improves the integrity and appearance smoothness between the green light emitting mechanism 50 and the power unit 22. The main body part of the whole portable vacuum cleaner reduces interfaces and cross-sections, and can reduce the risk of the user's hand being pinched.

[0091] Of course, in other embodiments, the green light emitting mechanism 50 can also be non-integrally designed with the power unit 22, and the power unit 22 and the handheld unit 10 can also be non-integrally designed to achieve other functions, such as the handheld unit 10 being foldable relative to the power unit 22, the green light emitting mechanism 50 being rotatable relative to the power unit 22, etc. However, these designs sacrifice the simplicity of the portable vacuum cleaner, and the production cost and selling price will also increase.

[0092] As Figure 2 and Figure 5As shown, further in this embodiment, the first housing 31 is formed by splicing a first side housing 31a and a second side housing 31b, and the third housing 33 is formed by splicing a third side housing 33a and a fourth side housing 33b. The third side housing 33a is integrally formed by protruding downward from the first side housing 31a, and the fourth side housing 33b is integrally formed by protruding downward from the second side housing 31b. This facilitates the assembly, disassembly, and maintenance of the hand-held portion 10, the power portion 22, and the green light emitting mechanism 50.

[0093] As Figure 2 , Figure 5 and Figure 6 shown, a rechargeable battery 11 and a control main board 12 are provided inside the hand-held portion 10, and a charging port 13 is provided at the bottom end of the hand-held portion 10 for charging the rechargeable battery 11. Compared with the design of replacing dry batteries, the use of the rechargeable battery 11 can be recycled and is more environmentally friendly.

[0094] An electrical connection is formed between the control main board 12, the green light emitting mechanism 50, and the fan assembly 40. A switch component 14 is provided on the control main board 12, and a switch button 15 is correspondingly provided on the side surface of the hand-held portion 10 of the first housing 31. The switch button 15 is used to drive the action of the switch component 14, and the switch button 15 is used to control the opening and closing of the green light emitting mechanism 50 and the fan assembly 40 through the control main board 12.

[0095] Setting the switch component 14 and the switch button 15 on the side surface of the hand-held portion 10 is more in line with the hand shape of the user. As Figure 1 shown, when the user holds the hand-held portion 10, the pulp of the thumb or index finger just reaches the position of the switch button 15. Therefore, compared with the design in which the switch is provided on the front side of the hand-held portion 10, the design of this embodiment can make the user's operation more comfortable.

[0096] As Figure 6 shown, the front end of the second housing 32 has a dust suction head mounting structure 61 for mounting and replacing the dust suction head 62. Thus, the user can replace the corresponding dust suction head 62 according to the actual shape and material of different surfaces to be cleaned. Similarly, the dust suction head mounting structure 61 can be a circumferential screwing connection, an axial snap connection, or a radial interference connection; the circumferential screwing connection can adopt a thread screwing structure, a snap-fit groove screwing structure, etc.

[0097] A filter cover 63 is provided inside the dust storage portion 21, and the filter cover 63 covers the periphery of the second air outlet c2.
