DETAILED DESCRIPTION

[0032] The following will be combined with the Figure 1 To the attached Figure 9 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that if the directions involved in the embodiments of the present invention are based on those shown in the accompanying drawings, if a specific posture changes, the directional indication will also change accordingly.

[0034] As a portable vacuum cleaner, handheld vacuum cleaners are very popular and are often used for cleaning at home or in places such as cars.

[0035] However, when using an existing handheld vacuum cleaner, the grip of the handheld vacuum cleaner will squeeze the user's hand, which makes the user's hand feel uncomfortable when operating the handheld vacuum cleaner for a long time.

[0036] In this regard, the applicant provides a handheld vacuum cleaner, the purpose of which is to solve the problem of the grip of the existing handheld vacuum cleaner excessively squeezing the user's index finger during use, thereby causing discomfort to the user's hand.

[0037] Detailed, such as Figure 1 As shown, a handheld vacuum cleaner of the present technical solution includes a vacuum cleaner body 1, a gripping portion 2 is connected to one side of the vacuum cleaner body 1, and a vacuum rod 3 is provided on the other side of the vacuum cleaner body 1 away from the gripping portion 2, wherein the gripping portion 2 and the vacuum cleaner body 1 together form a gripping space 4, and an assisting member 5 is connected to the inner side of the gripping portion 2 facing the gripping space 4.

[0038] When in use, the user can place the middle finger of the hand against the upper part of the assisting member 5, the ring finger against the lower part of the assisting member 5, and then hold the gripping part 2 with all fingers, so that the middle finger can share the squeezing force exerted on the index finger and avoid excessive weight bearing on the index finger.

[0039] In addition, in another usage scenario, the handheld vacuum cleaner can also be operated by placing the index finger against the top of the assisting member 5 and then holding the grip 2 with the remaining fingers. The principle is to reduce the squeezing force originally exerted on the index finger by transferring the force acting on the index finger to the assisting member 5.

[0040] Preferably, Figure 2 As shown, the top of the assisting member 5 and the top inner end of the gripping portion 2 form a receiving space 6 with an opening 61 facing the gripping space.

[0041] It should be understood that the accommodating space 6 is used to place the user's index finger and middle finger. When the user holds the grip part 2, the index finger is stacked on top of the middle finger, and the index finger and the middle finger are bent toward the grip part 2 at the same time to grip the grip part 2, and part of the weight of the grip part 2 is distributed on the index finger and the middle finger, so as to alleviate the problem that when the original handheld vacuum cleaner is in use, only the index finger bears the weight of the handheld vacuum cleaner, which makes the index finger easily uncomfortable.

[0042] Further, such as Figure 3 As shown, the assisting member 5 is connected to the intersection position C of the extension line F of the axis of the vacuum rod 3 and the gripping portion 2 .

[0043] It should be understood that the assisting member 5 is the area of ​​force applied by the user when operating the handheld vacuum cleaner. When the handheld vacuum cleaner is working, it is generally tilted at a certain angle to the surface of the object being cleaned, thus forming a Figure 4 The center of gravity line G is shown. At this point, the force-applying area lies on this line. According to the principle of vertical moment balance, gravity acts on the center of gravity, while support or other forces act on the point of application. When the point of application and the center of gravity are aligned, the moment arms of gravity and support are zero. This means that, whether the object is stationary or moving, the points of application and the center of gravity are aligned, and the moments in all directions are balanced, making the object more stable and less likely to tip over.

[0044] Therefore, when the user's fingers hold the power-assisting member 5, when the handheld vacuum cleaner is used and moved, unnecessary shaking can be reduced because the power point is on the center of gravity. The user will feel more stable during operation, improving work efficiency and quality.

[0045] In addition, since the assisting member 5 is connected to the extension line F of the axis of the dust collection rod 3, when the handheld vacuum cleaner is in use, the dust collection rod 3 is subjected to a force inclined to the bottom surface and downward. The assisting member 5 is arranged on the extension line of the axis of the dust collection rod 3, and the force direction of the assisting member 5 is consistent with the force direction of the dust collection rod 3, so that the user can more accurately control the movement direction and force of the dust collection rod 3 through the assisting member 5.

[0046] Further, such as Figures 1 to 4 As shown, the assisting member 5 and the gripping portion 2 are an integrally connected structure. Preferably, in this embodiment, the assisting member 5 and the gripping portion 2 are manufactured by integral molding. For example, casting, forging, injection molding, etc., during the manufacturing process, the raw materials are directly processed into the required shape and structure to achieve an integral connection. Due to the integral molding, the continuity of the material is maintained, and it can withstand greater external forces and there are no weak links such as seams, welds or bolt connections that may exist in traditional connection methods. The connection between the assisting member 5 and the gripping portion 2 is tight and firm, and will not be deformed or dislocated due to long-term use.

[0047] In addition, Figure 5 As shown, the assisting member 5 is detachably connected to the grip portion 2. For example, a slot 21 is provided in the grip portion 2, and the assisting member 5 is snapped into the slot to connect the grip portion 2 and the assisting member 5. This facilitates changing the shape of the assisting member 5 to better match the hand sizes of different users.

[0048] Preferably, Figure 6As shown in the top view, the junction between the power-assisting member 5 and the gripping portion 2 is an arc-shaped curve so as to fit the curve of the inner side of the gripping portion 2 .

[0049] It should be understood that such a design enables the joint between the assisting member 5 and the holding portion 2 to be subjected to balanced force, so that the assisting member 5 can withstand a greater force, and the joint between the assisting member 5 and the holding portion 2 is more secure, preventing the assisting member 5 from bending from the holding portion 2.

[0050] Further, such as Figure 3 and Figure 6 As shown, the assisting members 5 are symmetrically arranged on both sides of the extension line F of the axis of the suction rod 3 as the center line.

[0051] It should be understood that, since the fingers are in a curved holding posture when they rest on the assisting member 5, the assisting member 5 is symmetrically arranged on both sides of the extension line F of the axis of the vacuum rod 3 as the center line to expand the area of ​​the contact surface with the fingers. Since the pressure is based on the ratio of the force acting vertically on the surface of the object to the force-bearing area, that is, P=F / S (where F represents pressure, represents the force acting vertically on the surface of the object, and S represents the force-bearing area), it can be seen that under the same force, the larger the force-bearing area, the smaller the force acting vertically on the surface of the object. Therefore, expanding the area of ​​the contact surface between the assisting member 5 and the fingers can further reduce the pressure of the fingers on the assisting member 5, thereby increasing the service life of the assisting member 5.

[0052] Furthermore, the assisting member 5 has an upper end surface 51 and a lower end surface 52 ; the longitudinal sections of the upper end surface 51 and the lower end surface 52 are arc-shaped.

[0053] As Figure 3 The direction from top to bottom in the illustrated paper is the longitudinal cross-sectional direction. It should be understood that with this design, when a finger passes through the assisting member 5, the finger can move along the arc-shaped curved surface until it stops at the intersection of the assisting member 5 and the grip portion 2, making it easy for the user to quickly find the working position to operate the handheld vacuum cleaner.

[0054] Further, such as Figure 7 As shown, the junction of the upper end surface 51 and the lower end surface 52 facing the holding space 4 presents an arc-shaped transition.

[0055] It should be understood that with such a design, when the fingers are gripped from the outside toward the assisting member 5, the skin of the fingers first contacts the arc-shaped transition area before reaching the inside of the assisting member 5. The arc-shaped design avoids the feeling of being cut by a knife when the skin contacts it, and can effectively protect the skin of the hand and avoid skin damage.

[0056] Further, such as Figure 8 As shown, the upper end surface 51 and the lower end surface 52 respectively have a first anti-slip portion 511 and a second anti-slip portion 521. The first anti-slip portion 511 and the second anti-slip portion 521 are concave-convex structures provided on the surfaces of the upper end surface 51 and the lower end surface 52. The concave-convex structures can increase the static friction between the contact area between the hand skin and the power-assisting member 5, so as to prevent the fingers from slipping off the power-assisting member 5 during use of the handheld vacuum cleaner, thereby affecting the operation of the handheld vacuum cleaner.

[0057] Preferably, the thickness H of the assisting member 5 is 2 mm to 15 mm. The assisting member 5 having a thickness within this range is convenient for mold production and can also better withstand the applied force during actual use, making it convenient to use. Of course, the thickness of the assisting member 5 is not limited to this thickness range and can also have other thicknesses according to actual use.

[0058] In other usage scenarios, the longitudinal section of the assisting member 5 is as follows: Figure 9 When in use, the fingers grip the power-assisting member 5 along the recessed area 53, and the fingers cannot move longitudinally in the recessed area 53, which can effectively avoid the situation where the fingers cannot grip the handheld vacuum cleaner tightly when using the handheld vacuum cleaner.

[0059] In summary, a handheld vacuum cleaner comprises a vacuum cleaner body 1, a gripping portion 2 being connected to one side of the vacuum cleaner body 1, and a suction rod 3 being provided on the other side of the vacuum cleaner body 1 away from the gripping portion 2, wherein the gripping portion 2 and the vacuum cleaner body 1 together form a gripping space 4, and a power-assisting member 5 is connected to the inner side of the gripping portion 2 facing the gripping space 4. The power-assisting member 5 is made of materials such as plastic and metal according to actual use needs. The power-assisting member 5 provides the user with a clear indication of the gripping position, increases the contact area and friction between the hand and the gripping portion 2, enhances gripping stability, reduces hand fatigue and the risk of slipping, and its shape and position design conform to ergonomic principles and adapts to different hand shapes and gripping habits.
