Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a canister vacuum cleaner. Background Technology

[0002] Canister vacuum cleaners, as an essential tool for modern household cleaning, integrate mechanical design and aerodynamic principles in their technology. Their core function lies in using a motor to generate powerful suction, drawing dust and debris from floors and furniture into the machine. The cyclone separator, a key component of the canister vacuum cleaner, plays a crucial role. Utilizing centrifugal force, the cyclone separator effectively separates the sucked-in dust from the air, preventing dust from clogging the filter and ensuring the cleanliness of the exhaust air. However, under current technology, the connection between the cyclone separator and the motor housing has a problem of inadequate sealing. This structural flaw allows some fine dust particles to bypass the cyclone separator and directly enter the motor housing during vacuuming. This not only reduces the separation efficiency of the cyclone separator but may also damage the motor, shortening its lifespan. Furthermore, dust entering the motor housing can cause increased noise, motor overheating, and other problems, severely impacting the performance and user experience of the canister vacuum cleaner. In addition, the accumulation of dust inside the motor housing can pose a potential hygiene hazard, increasing the difficulty of cleaning and maintenance.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide a canister vacuum cleaner that can effectively solve the above-mentioned technical problems.

[0005] To achieve the purpose of this utility model, the following technical solution is adopted:

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not 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 on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 6As shown, a canister vacuum cleaner includes a housing 1 with a heat dissipation window 10, an exhaust component 7 located on one side of the housing 1, an assembly cavity 2 located at one end inside the housing 1, a dust collection cavity 3 located at the other end inside the housing 1, an air inlet channel 6 inserted into one side of the housing 1 and communicating with the interior of the dust collection cavity 3, a motor cover 4 located in the assembly cavity 2, a negative pressure fan 5 located in the motor cover 4, a cyclone separator 8 inserted into one end of the motor cover 4, and a dust cover 9 fitted onto the cyclone separator 8; wherein, one end of the dust cover 9 is provided with an insertion groove 80, and a connecting block 81 with a pad 82 is provided on the outside of the insertion groove 80. The cross-sectional shape of the pad is n-shaped. One end of the motor cover 4 is provided with an insertion block 41, which is inserted into the insertion groove 80, such that one side of the insertion block 41 abuts against the pad 82, and one side of the motor cover 4 abuts against the pad 82. In actual operation, the cyclone separator 8 is inserted into the motor cover 4, so that the plug block 41 is inserted into the plug slot 80, and one side of the motor cover 4 abuts against the pad 82, and one side of the plug block 41 abuts against the pad 82. On the one hand, this can prevent friction and collision when the motor cover 4 is connected to the dust cover 9. On the other hand, by setting the pad 82, both the plug block 41 and the motor cover 4 abut against the pad 82, achieving a two-stage isolation effect. This can effectively reduce the gap between the motor cover 4 and the dust cover 9 and prevent dust from being sucked into the motor cover 4.

[0028] In this embodiment, the pad 82 is made of rubber. By using rubber, the pad has elasticity, which can further reduce the gap between the motor cover 4 and the dust cover 9, and enhance the performance of this embodiment.

[0029] Furthermore, one side of the pad 82 is provided with several locking blocks 88, and one side of the connecting block 81 is provided with several slots 83 for inserting into the locking blocks 88. By inserting the locking blocks 88 into the slots 83, the pad 82 can be locked onto the connecting block 81, preventing the pad 82 from falling off the connecting block 81 and making it convenient for the user to replace it.

[0030] Furthermore, one end of the plug-in block 41 is provided with a sub-block 84, and the plug-in groove 80 is provided with a limiting hole 85 that engages with the sub-block 84. In this embodiment, the sub-block 84 has a circular cross-sectional shape. The cyclone separator 8 is screwed to the dust cover 9. One end of the cyclone separator 8 is provided with a connecting ring 87 with a fixing block 86. One end of the motor cover 4 is provided with a fixing hole 42 that engages with the fixing block 86. By correspondingly plugging the sub-block 84 into the limiting hole 85, it is convenient for the fixing hole 42 to be correspondingly plugged into the fixing block 86, effectively reducing the connection difficulty between the cyclone separator 8 and the motor cover 4 and improving the user experience.

[0031] Working principle: Insert the cyclone separator 8 into the motor cover 4 so that the plug block 41 is inserted into the plug slot 80, thereby causing one side of the motor cover 4 to abut against the pad 82, and one side of the plug block 41 to abut against the pad 82, so that both the plug block 41 and the motor cover 4 abut against the pad 82, achieving the effect of two-stage isolation.
