Description

Technical Field

[0001] The present application belongs to the field of garden power tools, and specifically relates to a garden blower. Background Art

[0002] A blower is a commonly used garden power tool, which is mainly used to use airflow to clean fallen leaves, grass clippings, road dust, snow, etc.

[0003] A garden blower mainly includes a casing, a motor fan blade assembly and electronic components arranged in the casing. The casing is generally made up of two casing units, and the spliced ​​casing units are fastened by fixings such as bolts. Since the garden blower itself is heavy and is also hand-held, some garden blowers are provided with wearable accessories on the casing, which are worn on the operator's body to reduce the operator's hand load.

[0004] Through understanding of relevant technologies, it is found that the wearable accessories of some garden blowers are generally connected to the casing by connectors, and the connectors are provided with holes for connecting to the wearable accessories. However, the connectors are mainly used to install the wearable accessories, and the functionality of the connectors themselves is relatively simple. Utility Model Content

[0005] The purpose of the utility model is to solve the defects of the prior art and provide a garden blower.

[0006] In order to achieve the above purpose, the technical solution adopted in this application is as follows:

[0007] A garden blower comprising:

[0008] chassis;

[0009] A motor fan blade assembly is arranged in the casing;

[0010] Wherein, the casing is formed by splicing at least two casing units;

[0011] A connecting piece is installed on the casing, and the connecting piece is suitable for installing accessories;

[0012] After the connecting piece is installed on the casing, it can clamp and fix two adjacent casing units that are spliced ​​to each other.

[0013] Through the above technical scheme, the present application installs a connector on the spliced ​​casing. The connector has a dual function. One function is to install accessories. The human body can hang the garden blower through the accessories to reduce the load on the arm. The other function is to clamp and fix the spliced ​​casing unit to ensure that the spliced ​​casing unit is assembled more firmly.

[0014] Further, the connecting piece comprises:

[0015] Connector body;

[0016] A first connection portion, connected to the connection member body, and suitable for mounting accessories on the first connection portion;

[0017] A second connection portion is provided at both ends of the connection body and connected to the connection body;

[0018] After the connecting piece is installed on the casing, the second connecting portion can be buckled with the clamping portion on the casing unit, thereby clamping two adjacent spliced ​​casing units.

[0019] Furthermore, the connector body is an arc-shaped structure, and after the connector is installed on the housing, the connector body is adapted to the surface of the housing;

[0020] The first connection portion is tilted upward relative to the surface of the connection member body.

[0021] Furthermore, when the second connecting portion is buckled with the snap-fitting portion on the housing unit, the connector body is in an expanded state, and the expanded arc-shaped connector body itself has a clamping force, and the size of the clamping force can be adjusted by the thickness and material of the connector body itself.

[0022] Furthermore, a clamping groove is provided on the clamping portion, and when the connecting member is installed, the second connecting portion is clamped with the clamping groove.

[0023] Furthermore, a clamping guide surface is provided on the clamping portion, and an extrusion surface corresponding to the clamping guide surface is provided at the end of the second connecting portion. When the connecting piece is installed, the clamping guide surface and the extrusion surface are in sliding contact, so that the second connecting portion expands toward the outside of the casing unit.

[0024] Through the above technical scheme, when the connector is installed on the casing, the extrusion surface at the end of the second connector first contacts the clamping guide surface on the clamping part. When the connector and the casing are relatively squeezed, the clamping guide surface applies an extrusion force to the extrusion surface. Under the action of the extrusion force, the two second connectors are opened to both sides relative to the connector body. At this time, the connector body is in an open state. When the relatively sliding clamping guide surface and the extrusion surface are separated, the extrusion force exerted on the second connector disappears, and the connector body is reset. At this time, the second connector is engaged with the clamping groove on the clamping part. At this time, the connector can be clamped on the outside of the two casing units. In actual design, after the second connector is engaged with the clamping groove, the connector body can be in an expanded state, so that a clamping force can be applied to the spliced ​​casing units, thereby improving the splicing firmness of the casing units.

[0025] Furthermore, the two mutually spliced ​​casing units are connected via a fixing member, which may be a bolt.

[0026] Furthermore, a mounting hole is provided on the second connecting part. After the second connecting part is engaged with the clamping part, the fixing piece passed through the mounting hole is fixedly connected with the clamping part. The fixing piece on the second connecting part mainly plays an auxiliary fixing role for the engaged second connecting part, so as to prevent the installed connecting piece from falling off from the casing due to external force.

[0027] Furthermore, the housing has a handle, and the connecting piece is arranged below the handle.

[0028] Through the above technical solution, since one of the functions of the connecting piece is to install accessories, when a person picks up the garden blower, the force is generally applied to the handle. After the connecting piece is set at the installation position of the handle, the traction force of the accessory connected to the connecting piece on the casing is also close to the handle. When the garden blower is working, the traction force generated by the accessory can directly reduce the load on the human hand.

[0029] Furthermore, a longitudinal protrusion for the installation and positioning of the connector is provided on the connector body. The longitudinal protrusion mainly plays a fool-proof role to prevent the connector from being installed upside down on the casing.

[0030] Furthermore, the inclination angles of the clamping guide surface and the extrusion surface are consistent.

[0031] Furthermore, a butt joint rib is provided on the joint surface of one housing unit, and a butt joint notch corresponding to the butt joint rib is provided on the joint surface of the other housing unit.

[0032] Through the above technical solution, when two housing units are spliced ​​together, the matching butt ribs and butt notches are butted together, thereby improving the neatness of the splicing of the two housing units.

[0033] The beneficial effects of the utility model are as follows: a connecting piece is installed on the casing of the present application, and the connecting piece has a dual function. One function is to install accessories, and the human body can hang the garden blower through the accessories to reduce the load on the arm. The other function is to clamp and fix the spliced ​​casing units to ensure that the spliced ​​casing units are assembled more firmly. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Reference Figures 1 to 4 A garden blower 100 includes a housing 10 and a motor fan blade assembly 11 disposed in the housing 10, wherein the housing 10 is formed by splicing at least two housing units 101, and the two mutually spliced ​​housing units 101 are connected by a fixing member, and the fixing member can be a bolt;

[0044] A connector 20 is installed on the casing 10. The connector 20 is used to install accessories. After the connector 20 is installed on the casing 10, it can clamp and fix two casing units 101 that are spliced ​​to each other. The connector 20 has a dual role. One role is to install accessories. The human body can hang the garden blower 100 through the accessories, thereby reducing the load on the arm. The other role is to clamp and fix the spliced ​​casing units 101 to ensure that the spliced ​​casing units 101 are assembled more firmly.

[0045] In this embodiment, a joint rib 101a is provided on the joint surface of one housing unit 101, and a joint groove 101b corresponding to the joint rib 101a is provided on the joint surface of the other housing unit 101. When the two housing units 101 are spliced ​​together, the matching joint ribs 101a and the joint groove 101b are connected to improve the neatness of the splicing of the two housing units 101.

[0046] Furthermore, the housing 10 has a handle 30, and the connecting member 20 is arranged at the installation position of the handle 30. Since one of the functions of the connecting member 20 is to install accessories, when a person picks up the garden blower 100, the handle 30 is generally subjected to force. After the connecting member 20 is arranged at the installation position of the handle 30, the traction force of the accessory connected to the connecting member 20 on the housing 10 is also close to the handle 30. When the garden blower 100 is working, the traction force generated by the accessory can directly reduce the load on the human hand.

[0047] Specifically, refer to Figures 4 to 7 The connector 20 includes a connector body 201, a first connecting portion 202 connected to the connector body 201, and a second connecting portion 203 arranged at both ends of the connector body 201 and connected to the connector body 201, wherein the first connecting portion 202 is used to install accessories. In addition, in some embodiments, the first connecting portion 202 is upwardly tilted relative to the surface of the connector body 201. After the first connecting portion 202 is tilted, it is convenient for accessories to be connected thereto. Moreover, when the connector 20 is installed on the housing 10, the tilted first connecting portion 202 is convenient for human hands to hold, and the connector 20 is convenient to be assembled and disassembled on the housing 10.

[0048] After the connecting member 20 is installed on the housing 10 , the second connecting portion 203 can be engaged with the clamping portion 102 on the housing unit 101 , thereby clamping the two connected housing units 101 .

[0049] In some embodiments, the accessory may include a strap, and may also include, for example, a hook, a tool kit, etc. When the accessory is a strap, the strap may be hung on a person's body, and the hanging strap may reduce the load of the garden blower 100 on the person's arms;

[0050] In addition, when the garden blower 100 is used in conjunction with a backpack battery pack, the backpack battery pack has a shoulder strap and a waist belt. The shoulder strap is placed on the shoulders of the human body, and the waist belt is wrapped around the waist of the human body. A traction belt with a hook at the end can be led out from the side of the waist belt, and the hook of the traction belt can be connected to the first connecting part 202. When the user uses the garden blower 100 by hand, the weight of the garden blower 100 is mainly borne by the waist belt, and the hand is used to control the blowing direction of the garden blower 100. It should be noted that the backpack battery pack is generally connected to the garden blower 100 via a wire and supplies power to the garden blower 100.

[0051] Furthermore, in some embodiments, a card slot 103 is provided on the card connection portion 102 , and when the connecting member 20 is installed, the second connecting portion 203 is engaged with the card slot 103 .

[0052] In addition, in some embodiments, a clamping guide surface 104 is provided on the clamping portion 102, and an extrusion surface 204 corresponding to the clamping guide surface 104 is provided at the end of the second connecting portion 203. Preferably, the inclination angles of the clamping guide surface 104 and the extrusion surface 204 are consistent. When the connecting member 20 is installed, the clamping guide surface 104 is in sliding contact with the extrusion surface 204.

[0053] Furthermore, the connector body 201 is in an arc-shaped structure. When the second connecting portion 203 is buckled with the clamping portion 102 on the housing unit 101, the connector body 201 is in an expanded state. The expanded arc-shaped connector body 201 itself has a clamping force, and the magnitude of the clamping force can be adjusted by the thickness and material of the connector body 201 itself. Specifically, when the connector 20 is installed on the housing 10, the extrusion surface 204 at the end of the second connecting portion 203 first contacts the clamping guide surface 104 on the clamping portion 102. When the connector 20 and the housing 10 are relatively squeezed, the clamping guide surface 104 applies an extrusion force to the extrusion surface 204. Under the action of the extrusion force, the two second connecting portions 203 are relatively squeezed. The connector body 201 opens to both sides (expands toward the outside of the housing unit 101). At this time, the connector body 201 is in an open state. When the relatively sliding snap-in guide surface 104 and the extrusion surface 204 are separated, the extrusion force on the second connecting portion 203 disappears, and the connector body 201 is reset. At this time, the second connecting portion 203 is engaged with the slot 103 on the snap-in portion 102. At this time, the connector 20 can be clamped on the outside of the two housing units 101. In actual design, after the second connecting portion 203 is engaged with the slot 103, the connector body 201 can be in an expanded state, so that a clamping force can be applied to the spliced ​​housing units 101 to improve the splicing firmness of the housing units 101.

[0054] In addition, a mounting hole 205 is provided on the second connecting portion 203. After the second connecting portion is engaged with the clamping portion 102, the fixing member (screw 206) passed through the mounting hole 205 is fixedly connected to the clamping portion 102; the fixing member (screw 206) on the second connecting portion 203 mainly plays an auxiliary fixing role for the engaged second connecting portion 203, so as to prevent the installed connecting member 20 from falling off from the casing 10 due to external force.

[0055] In some embodiments, a longitudinal protrusion 207 for installing and positioning the connector 20 is provided on the connector body 201 . The longitudinal protrusion 207 mainly serves to prevent the connector 20 from being installed upside down on the housing 10 .

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
