Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to a suction device. Background Technology

[0002] A cleaning vehicle is a multi-functional cleaning device used for cleaning and hygiene. It is widely used for cleaning operations and material handling in public places such as hotels, shopping malls, commercial buildings, real estate developments, hospitals, schools, offices, libraries, exhibition centers, clubs, and private clubs.

[0003] The cleaning cart has a suction hose and a handle. Operators use the handle to operate the suction hose to suck up debris. The suction hose on the cleaning machine requires the operator to get very close to the debris to draw it in. Furthermore, the hose is quite long, making it inconvenient for users and requiring them to bend over. This puts significant pressure on the operator's hands during operation, greatly increasing workload and causing extreme fatigue. Prolonged operation may also negatively impact the operator's health.

[0004] Therefore, it is necessary to design a suction device that can reduce the hand load of operators and reduce labor intensity. Utility Model Content

[0025] Please refer to Figure 1 and Figure 2 As shown in the figure, an embodiment of this application provides a suction device 100, which is installed on a cleaning machine 200 for sucking up garbage and dust. The suction device 100 includes a suction pipe 10, a handle 20, and a weight-reducing structure 30. The handle 20 is installed on the suction pipe 10, and the user operates the suction pipe 10 to suck up garbage and dust by using the handle 20. The weight-reducing structure 30 is installed on the suction pipe 10 or the handle 20, and the weight-reducing structure 30 is used to reduce the physical load on the user's hands when operating the handle 20.

[0026] Specifically, the suction device 100 of this application is connected to the suction mechanism inside the cleaning machine 200 for sucking up garbage and dust on the ground. The suction device 100 includes a suction pipe 10, a handle 20, and a weight-reducing mechanism 30. One end of the suction pipe 10 is connected to the suction mechanism inside the cleaning machine 200, and the other end is located outside for workers to suck up garbage and dust. The handle 20 is mounted on the suction pipe 10 and is held by the user to control the position and direction of the suction pipe 10, thereby aiming it at the garbage on the ground. The weight-reducing structure 30 is disposed on the suction pipe 10 or the handle 20 and is used to transfer the weight of the suction pipe 10 from the hand to other positions. In some embodiments, the weight is transferred to the shoulder of the worker, so that the shoulder bears most of the weight, thereby reducing the load on the worker's hands and reducing labor intensity.

[0027] In one optional embodiment, the weight-reducing structure is a pull rope or lever mounted on the suction pipe or handle. Specifically, the weight-reducing structure is a pull rope mounted on the suction pipe or handle, which the user holds by hand for ease of use. In another embodiment, the weight-reducing structure is a lever mounted on the suction pipe or handle, which the user holds with one hand to reduce the physical burden on the operator's hands.

[0028] like Figure 2 As shown, in an optional embodiment, the weight-reducing structure 30 is a strap mounted on the suction pipe 10 or the handle 20. Specifically, this strap is a shoulder strap or a back strap, with a wider shoulder strap to reduce the pressure on the worker's shoulders, thereby reducing the worker's labor intensity. After long periods of work, the worker will not feel shoulder pain, greatly reducing the probability of developing occupational diseases from long-term work.

[0029] In an optional embodiment, the handle 20 includes a handle rod 22 and a connector 21. One end of the handle rod 22 is connected to the connector 21, and the connector 21 is mounted on the suction pipe. The handle rod 22 is positioned at the end of the suction pipe 10 via the connector 21, making it easier for operators to control the suction pipe 10 and for the suction nozzle of the suction pipe 10 to be more easily aimed at the debris on the ground. In some embodiments, the handle rod 22 and the connector 21 are connected by threads. The connector 21 has a threaded hole, and the outer wall of the handle rod 22 has threads. Through the threaded engagement, the handle rod 22 can be detachably mounted on the connector 21 for easy maintenance.

[0030] The connector 21 includes a hollow tube 211 and a fixing part 212 connected to each other. One end of the handle 22 is mounted on the fixing part 212, and the other end of the handle 22 extends toward the end of the suction pipe 10 away from the connector 21. The suction pipe 10 is sleeved on the hollow tube 211 to fix the hollow tube 211 to the end of the suction pipe 10. To increase the stability of the fixation between the hollow tube 211 and the suction pipe 10, the hollow tube 21 and the suction pipe 10 are interference-fitted.

[0031] The handle lever 22 includes a first lever 221 and a second lever 222 connected at an angle. One end of the first lever 221 is mounted on the fixing part 212, and the other end of the first lever 221 is connected to the second lever 222. The axis of the first lever 221 is parallel to the axis of the hollow tube 211, and the second lever 222 is bent towards the suction tube 10. Figure 2As shown, the operator holds the first lever 221 with their left hand and the second lever 222 with their right hand, facilitating control of the suction pipe 10. This allows the user to aim the suction pipe at the trash on the ground without bending over, thus completing the trash removal operation. The axis of the first lever 221 is parallel to the axis of the hollow tube 211, ensuring that the movement of the first lever 221 and the end of the suction pipe 10 are approximately synchronized, further facilitating user control of the end of the suction pipe 10.

[0032] In an optional embodiment, the first rod 221 and the second rod 222 are further fitted with grip sleeves to increase the friction between them and the operator's hand, so as to facilitate the operator's operation.

[0033] In an optional embodiment, the handle 20 is a hollow structure. The handle 20 also has a certain weight; making it hollow reduces its weight, thereby further reducing the labor intensity of the operator.

[0034] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
