[0027] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0028] Please refer to Figures 1-5 As shown in the preferred embodiment of this application, a handheld vacuum cleaner includes a main body and a housing. The main body is configured to generate negative pressure to suck up target objects. The housing includes a suction housing 11, a motor housing 12, and a handheld housing 13 connected to the motor housing 12. Specifically, the main body is located within the suction housing 11, the motor housing 12 is adapted to house a motor, and the handheld housing 13 serves two purposes: firstly, it is used by the user for gripping; secondly, it is adapted to house a power source connected to the motor.

[0029] In an optional embodiment, the motor housing 12 is provided with a groove 121 along the circumference, which is suitable for attaching at least two types of membrane structures 2 to meet the user's personalized customization needs for the motor housing 12. It should be noted that in this embodiment, the at least two types of membrane structures 2 can be membrane structures 2 of different colors and patterns.

[0030] In an optional embodiment, the thickness of the membrane structure 2 is less than or equal to the height of the recess 121 to ensure that the membrane structure 2 is attached to the recess 121 and does not protrude from the surface of the motor housing, thus ensuring the aesthetic appearance of the entire vacuum cleaner and preventing the edges of the membrane structure 2 from curling up during long-term use.

[0031] In this embodiment, the height of the settling tank 121 is 0.5 mm, and the thickness of the membrane structure 2 is 0.35 mm. In other embodiments, the height of the settling tank 121 and the thickness of the membrane structure 2 are not specifically limited.

[0032] In an optional embodiment, the motor housing 12 is further provided with a retaining groove 122, and the handheld housing 13 is provided with a retaining protrusion 131 adapted to the retaining groove 122. The motor housing 12 is configured such that the membrane structure 2 is attached to the recess 121 and the two ends of the membrane structure 2 are located in the retaining groove 122 and are engaged and fixed with the retaining protrusion 131 of the handheld housing 13. That is, during assembly, the membrane structure 2 needs to be attached to the sink 121 first, so that both ends of the membrane structure 2 extend into the retaining groove 122. Then, the motor housing 12 is engaged with the handheld housing 13 through the retaining groove 122 and the retaining protrusion 131. On the one hand, this prevents the two ends of the membrane structure 2 from warping, and on the other hand, it can achieve double fixation of the membrane structure 2, preventing the lack of adhesion between the membrane structure 2 and the sink 121. The engagement of the retaining groove 122 and the retaining protrusion 131 can also ensure that the membrane structure 2 will not detach from the sink 121. At the same time, the cooperation of the retaining groove 122 and the retaining protrusion 131 can also fix the motor housing 12 and the handheld housing 13. The operation is simple and convenient for users to install and replace the membrane structure 2 themselves.

[0033] It should be noted that in this embodiment, the sink 121 is connected to the retaining groove 122, and an arc-shaped transition surface 123 is provided at the connection between the sink 121 and the retaining groove 122 to prevent wear on the membrane structure 2.

[0034] In one optional embodiment, the retaining groove 122 is arched. In other embodiments, the retaining groove 122 can also be set as an arc, wave, or other shapes. Compared with a retaining groove 122 with a straight contact surface, this design can increase the retaining stability between the retaining groove 122 and the retaining protrusion 131. On the other hand, this design can also disperse the pressure at the end of the membrane structure 2 and reduce the risk of damage to the membrane structure 2 due to excessive local stress.

[0035] In an optional embodiment, the handheld vacuum cleaner further includes an isolation structure comprising a first isolation member 31 covering the retaining groove 122 and a second isolation member 32 covering the retaining groove 122. When the motor housing 12 is engaged with the handheld housing 13, the end of the membrane structure 2 is located between the first isolation member 31 and the second isolation member 32. In this embodiment, the isolation structure is made of silicone rubber.

[0036] Understandably, by setting an isolation structure made of silicone rubber, which has good elasticity and weather resistance, the isolation structure can quickly return to its original shape when the end of the membrane structure 2 is squeezed by the retaining groove 122 and retaining protrusion 131 for a long time and needs to be replaced. This prevents the membrane structure 2 from being stuck or damaged due to prolonged direct contact with the retaining groove 122 and retaining protrusion 131, thus extending the service life of the membrane structure 2 and facilitating its replacement. It also helps maintain the stability and reliability of the connection between the handheld housing 13 and the motor housing 12.

[0037] It should be noted that in this embodiment, the end of the membrane structure 2 does not have an adhesive layer.

[0038] In an optional embodiment, the membrane structure 2 includes an attachment area 21 and a connection area 22. The attachment area 21 is used to attach to the groove 121 of the motor housing 12 by an adhesive layer. The connection area 22 is located between the retaining groove 122 and the retaining protrusion 131. The connection area 22 is also provided with a removable protective layer.

[0039] Understandably, the membrane structure 2 is divided into an attachment area 21 and a connection area 22. The attachment area 21 is attached to the sink 121 through an adhesive layer, which ensures a tight connection between the membrane structure 2 and the motor housing 12. The connection area 22 is provided with a detachable protective layer, which can protect the connection area 22 of the membrane structure 2 and prevent it from being damaged during use. If the protective layer is damaged, only the protective layer needs to be replaced without replacing the entire membrane structure 2.

[0040] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
