DETAILED DESCRIPTION
[0015] Example
[0016] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0017] In the following, in conjunction with the accompanying drawings, a dry grinder dust collection pipe connection structure provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.
[0018] refer to Figure 1-3 , a dry grinder dust suction pipe connection structure provided in an embodiment of the present application may include:
[0019] Combination Figure 1 The switch assembly 2 of the dry grinder is located on the housing 1, and the housing 1 also includes a vibration component 4 and an eccentric component 5 in order. The energy component 8 provides electrical energy to the vibration component 4 of the dry grinder. The vibration component 4 is a motor, which drives the grinding component 6 to work. The above components are common components of the dry grinder. Please refer to the description of the utility model patent document with application number: 2024212963790.
[0020] The shock-absorbing member 3 is provided with a base 31, a notch 32 and a protrusion 33; the base 31 is a stamped sheet metal part, which is enclosed into a rotating body structure after stamping. The notch 32 and the protrusion 33 are located on the base 31, and there are a plurality of notches 32 and protrusions 33, which correspond to each other one by one and are formed by stamping. The protrusion 33 is an arc-shaped structure, and the protrusion 33 is bent away from the port connected to the base 31, and its arc curvature is preferably matched with the inner cavity of the shell 1 accommodating the structure, so that the shock-absorbing member 3 and the shell are in good contact, the force is evenly applied, and the service life of the shock-absorbing member 3 is extended.
[0021] The base 31 is a rotating body structure, and the base 31 is hollow, and the motor is accommodated in the hollow part. The base 31 can be a discontinuous structure. When the base 31 contacts the vibration component 4 at several points, the point contact referred to here should be uniform circumferential point contact, so that the body 31 is evenly stressed. The base 31 contacts the shell 1 at one point, and the point contact referred to here should also be uniform circumferential point contact. The above two types of point contacts, the several point contacts between the base 31 and the vibration component 4 and the point contact between the base 31 and the shell 1, should not be on the same plane to avoid the shock absorber 3 only acting as an intermediate component without a shock absorbing effect.
[0022] The cover 9 is provided with a dust outlet duct 90; Figure 2 As shown, the dust exhaust duct 90 is preferably a rotating body structure, which is convenient for centering the dust exhaust duct 90 and the connecting piece 10, and also convenient for centering when snapping and connecting. The dust exhaust duct 90 can also be a regular polygonal structure or a regular arc structure, such as a cube, a regular hexagonal prism, an elliptical cylinder, etc. These shapes can also be centered when snapping and connecting.
[0023] The external dust collection component 7 includes a connector 10, a dust collection bag 71 and a dust collection pipe 72. The dust collection bag 71 and the dust collection pipe 72 can be blow-molded as one piece. A non-woven dust collection bag is also provided in the dust collection bag 71 to facilitate dust collection and allow air to escape. The connector 10 is located between the dust collection pipe 72 and the dust outlet pipe 90. Figure 2 As shown, the connector 10 is threadedly connected to the dust suction pipe 72 , and the connector 10 is snap-connected to the dust outlet pipe 90 .
[0024] The dust outlet duct 90 is provided with a T-shaped opening 901. Figure 4 and Figure 5As shown, an elastic portion 102 is provided on the connector 10, and a protrusion 104 is provided at the end of the elastic portion 102. A hollow space 103 is formed between the protrusion 104 and the elastic portion 102, and a notch 101 is provided on the connector 10 corresponding to the area of the protrusion 104 and the elastic portion 102. The protrusion 104 is snapped into the T-shaped opening 901. The elastic portion 102 and the protrusion 104 are integrally formed with the connector 10, and the elastic portion 102 is similar to a rib. At the end where the elastic portion 102 and the protrusion 104 are connected, a notch 101 is provided on the connector 10, so that the end where the elastic portion 102 and the protrusion 104 are connected does not contact the connector 10. It is in a suspended state. The end of the elastic portion 102 away from the protrusion 104 is integrally injection molded with the connector 10. A hollow space 103 is formed between the elastic portion 102 and the protrusion 104, and the protrusion 104 is an arc-shaped structure. As shown Figure 5 As shown, the structure of the hollow 103 allows the elastic part 102 and the protrusion 104 to be compressed and deformed, and then the elastic part 102 and the protrusion 104 can slide into the T-shaped opening 901, and then the protrusion 104 can enter the wider part of the T-shaped opening and get stuck. Figure 2 shown.
[0025] The raised portion 104 corresponds to the T-shaped opening 901 one by one, and the combination of the raised portion 104 and the T-shaped opening 901 is at least one group. Preferably, there is an even number of groups, and the raised portion 104 and the T-shaped opening 901 are evenly distributed around the axis of the dust outlet pipe 90. This facilitates uniform force on the connector 10. Uniform force makes the connection reliable. Preferably, the dust outlet pipe 90 is a rotating body structure, and the dust suction pipe 72 is a rotating body structure. This facilitates reliable connection and centering.
[0026] The structure is a quick-connect plug-in type. When the grinding assembly 6 is working, the eccentric assembly 5 and the fan blades at its upper end send the dust and wind into the dust collection assembly 7. The dust collection bag 71 collects dust, and the rest of the air overflows. When the dust collection bag 71 is full of dust, the connector 10 and the dust collection tube 72 can be threadedly connected in advance, and then the connector 10 and the dust collection tube 72 are inserted into the dust outlet duct 90 together. The protrusion 104 falls into the T-shaped opening 901 to play a connecting role. When unplugging, the arc structure of the protrusion 104 deforms and slides in the T-shaped opening 901 to be pulled out. Plug-in replacement is quick. And the connection is reliable.
[0027] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
