Description

Technical Field

[0001] The utility model relates to the field of garden electric tools, in particular to a garden blower. Background Art

[0002] The internal electronic components of a garden blower include circuit boards, motors, controllers, and signal switches. When some garden blowers are powered by an external battery pack, the battery pack is connected to the electrical connection terminals inside the garden blower housing through a power cable, and the electrical connection terminals are connected to the controller through lines. When the electrical connection terminals and controllers inside the garden blower are installed, the compactness and stability of the installation are crucial. For example, if the distance between the electrical connection terminals and the controller is too large, there will be a large energy loss when the line between the electrical connection terminals and the controller supplies a large current. Therefore, it is crucial to improve the compactness of the connection between the electrical connection terminals and the controller. Utility Model Content

[0003] The purpose of at least one specific implementation mode of the utility model is to solve the defects of the prior art and provide a garden blower.

[0004] In order to achieve the above purpose, the technical solution adopted in this utility model is as follows:

[0005] A garden blower comprising:

[0006] Hold the case;

[0007] A controller is arranged in a receiving cavity inside the holding housing;

[0008] The holding housing comprises a holding portion, a main housing portion and a connecting portion for connecting the holding portion with the main housing portion;

[0009] The connecting portion bulges upward along the outer surface of the main housing to form an electrical connection portion, in which an electrical connection terminal assembly connected to the controller is provided. The electrical connection terminal assembly is located on one side of the controller and is suitable for connecting to an external power cable. The accommodating cavity is specifically the inner cavity of the main housing.

[0010] Furthermore, the inner diameter of the inner cavity of the electrical connection part gradually expands from top to bottom, and the cavity at the expanded end close to the main shell part covers the controller. The electrical connection terminal assembly is adjacently arranged above the controller and is located within the narrow diameter end of the electrical connection part. The projection of the electrical connection terminal assembly and the controller on the horizontal plane at least partially overlap.

[0011] Through the above technical scheme, the present application forms an inner cavity with a raised structure through the connecting portion for installing the electrical connection terminal assembly. The electrical connection terminal assembly will not occupy the space of the internal accommodating cavity of the main shell portion. Moreover, the cavity close to the expanded end of the main shell portion covers the controller. The electrical connection terminal assembly is adjacently arranged above the controller. The line connecting the electrical connection terminal assembly and the controller is relatively short. The electrical connection terminal assembly and the controller are relatively compactly installed. After the electrical connection terminal assembly is connected to the external battery pack, when the line between the electrical connection terminal assembly and the controller supplies a large current, the energy loss is small.

[0012] Furthermore, the electronic component part of the controller extends into the inner cavity of the electrical connection part.

[0013] Through the above technical solution, the inner cavity of the electrical connection part is an independent cavity relative to the internal accommodating cavity of the holding housing. The inner cavity of the electrical connection part can be used to accommodate the electronic component part of the controller while accommodating the electrical connection terminal assembly. The electronic component part above the controller and the electrical connection terminal assembly can be integrated in the inner cavity of the electrical connection part, further improving the compactness of the relative installation of the electrical connection terminal assembly and the controller.

[0014] Furthermore, the holding housing is formed by splicing two housing units.

[0015] Furthermore, the electrical connection terminal assembly includes an electrical connection terminal body and an electrical connection post arranged inside the electrical connection terminal body. One or more clamping members are provided on the inner wall of the electrical connection part. After the two housing units are spliced, the clamping members of the electrical connection part are clamped on both sides of the outside of the electrical connection terminal body.

[0016] Through the above technical solution, after the clamping piece is arranged on the inner wall of the electrical connection part, it can be used to clamp and fix the electrical connection terminal assembly, thereby ensuring the stability of the electrical connection terminal assembly in the inner cavity of the electrical connection part.

[0017] Furthermore, one end of the electrical connection terminal body extends to the side of the electrical connection part and forms a power cable plug interface. A flexible member is connected to the main shell, and the flexible member is connected to a sealing cover. The sealing cover is suitable for sealing the power cable plug interface.

[0018] Furthermore, the side surface of the electrical connection portion is constructed as a plug-in receiving surface, the central axis of the electrical connection terminal body is perpendicular to the plug-in receiving surface, and the plug-in direction of the power cable relative to the power cable plug interface is perpendicular to the plug-in receiving surface.

[0019] Through the above technical solution, when the power cable connected to the external battery pack is plugged into the power cable socket, if the plug-in bearing surface is perpendicular to the plug-in direction of the power cable, the plug-in operation between the power cable and the power cable socket will be relatively direct, and it is less likely to cause plug-in misalignment or plug-in obstruction.

[0020] Furthermore, a first support column is provided on the inner wall of the electrical connection part, and a first limit opening is provided on the first support column. The end of the first support column is also provided with an arc surface that matches the surface of the electrical connection terminal body. When the two housing units are spliced, the first support columns on both sides of the electrical connection terminal body clamp and fix the electrical connection terminal body through the arc surface.

[0021] Furthermore, a second support column is provided on the inner wall of the electrical connection part, and two clamping plates are connected to the second support column. A second limit opening is formed between the two clamping plates. A limit part is provided on the outer side of the electrical connection terminal body. When the two housing units are spliced, the second support columns on both sides of the electrical connection terminal body are engaged with the limit part through the second limit opening.

[0022] Further, the first supporting column and / or the second supporting column constitute a clamping member.

[0023] Through the above technical solution, the clamping member on the inner wall of the electrical connection part can be any one of the first support column and the second support column, or a combination of the first support column and the second support column. The purpose of setting the first support column and the second support column is mainly to clamp and fix the electrical connection terminal body to ensure the stability of the electrical connection terminal assembly in the inner cavity of the electrical connection part.

[0031] 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.

[0032] Reference Figure 1 , Figure 2 A garden blower 100 includes a grip casing 10 and a controller 12 arranged in a housing chamber 11 inside the grip casing 10, wherein the grip casing 10 includes a grip portion 101, a main casing portion 102, and a connecting portion 103 for connecting the grip portion 101 with the main casing portion 102. In this embodiment, the housing chamber 11 is specifically an inner cavity of the main casing portion 102.

[0033] In this embodiment, the connecting portion 103 bulges upward along the outer surface of the main shell portion 102 to form an electrical connection portion 104. The electrical connection portion 104 is provided with an electrical connection terminal assembly 20 connected to the controller 12. The electrical connection terminal assembly 20 is located on one side of the controller 12 and is suitable for connecting to an external power cable 30. The power cable 30 is mainly used to connect an external battery pack.

[0034] Further, the inner diameter of the inner cavity 105 of the electrical connection portion 104 gradually expands from top to bottom. Specifically, the end of the electrical connection portion 104 close to the main housing portion 102 forms an enlarged diameter end, and the end of the electrical connection portion 104 away from the main housing portion 102 forms a narrow diameter end. The controller 12 is arranged at the connection position between the inner cavity 105 and the accommodating cavity 11, and the cavity close to the enlarged diameter end of the main housing portion 102 covers the controller. The electrical connection terminal assembly 20 is adjacently arranged above the controller 12 and is located in the narrow diameter end of the electrical connection portion 104. Figure 2 When the garden blower is placed on a horizontal plane, the electrical connection terminal assembly 20 and the projection of the controller 12 relative to the horizontal plane at least partially overlap.

[0035] In the present application, the inner cavity 105 with a raised structure formed by the connecting portion 103 is used to accommodate the electrical connection terminal assembly 20. The electrical connection terminal assembly 20 will not occupy the space of the internal accommodating cavity 11 of the main housing portion 102. Moreover, the cavity near the expanded end of the main housing portion 102 covers the controller 12. The electrical connection terminal assembly 20 is adjacently arranged above the controller 12. The line 40 connecting the electrical connection terminal assembly 20 and the controller 12 is relatively short. The electrical connection terminal assembly 20 and the controller 12 are relatively compactly installed. After the electrical connection terminal assembly 20 is connected to the external battery pack through the plugged power cable 30, when the line 40 between the electrical connection terminal assembly 20 and the controller 12 supplies a large current, the power loss is small.

[0036] Further, refer to Figures 3 to 5 Since the controller 12 is arranged at the connecting position between the inner cavity 105 and the accommodating cavity 11, during installation, the electronic component part 121 on the controller 12 will extend into the inner cavity 105 of the electrical connection part 104. The inner cavity 105 of the electrical connection part 104 can be said to be an independent cavity relative to the internal accommodating cavity 11 of the main shell part 102. The inner cavity 105 of the electrical connection part 104 can be used to accommodate the electronic component part 121 of the controller 12 while accommodating the electrical connection terminal assembly 20. The electronic component part 121 above the controller 12 and the electrical connection terminal assembly 20 can be integrated in the inner cavity 105 of the electrical connection part 104, which further improves the compactness of the relative installation of the electrical connection terminal assembly 20 and the controller 12.

[0037] Furthermore, the electrical connection terminal assembly 20 includes an electrical connection terminal body 201 and an electrical connection post 202 arranged in the electrical connection terminal body 201, one end of the electrical connection terminal body 201 extends to the side of the electrical connection part 104 and forms a power cable plug interface 203, the side of the electrical connection part 104 is constructed as a plug-in bearing surface 106, wherein the central axis 204 of the electrical connection terminal body 201 is perpendicular to the plug-in bearing surface 106, the plug-in direction of the power cable 30 relative to the power cable plug interface 203 is perpendicular to the plug-in bearing surface 106, and the plug-in direction of the power cable 30 relative to the power cable plug interface 203 is consistent with the extension direction of the central axis 204 of the electrical connection terminal body 201.

[0038] When the power cable 30 connected to the external battery pack is plugged into the power cable plug interface 203, if the plug-in bearing surface 106 is perpendicular to the plug-in direction of the power cable 30, the plug-in operation between the power cable 30 and the power cable plug interface 203 will be relatively direct, and there is no need to adjust the plug-in angle manually, and it is not easy to have plug-in misalignment or plug-in obstruction problems.

[0039] In addition, in some embodiments, a flexible member 50 is connected to the main housing 102 , and the flexible member 50 is connected to a sealing cover 60 . When the power cable plug port 203 is not connected to the power cable 30 , the sealing cover 60 can seal the power cable plug port 203 .

[0040] In some embodiments, the holding housing 10 is formed by splicing two housing units 10a, and one or more clamping members are provided on the inner wall of the electrical connection part 104. After the two housing units 10a are spliced, the clamping members of the electrical connection part 104 are clamped on the outer sides of the electrical connection terminal body 201. After the clamping members are set on the inner wall of the electrical connection part 104, they can be used to clamp and fix the electrical connection terminal assembly 20 to ensure the stability of the electrical connection terminal assembly 20 placed in the inner cavity 105 of the electrical connection part 104.

[0041] Specifically, a first support column 70 is provided on the inner wall of the electrical connection portion 104, and a first limiting opening 701 is provided at the end of the first support column 70. When the two housing units 10a are spliced, the first support columns 70 on both sides of the electrical connection terminal body 201 limit the end of the electrical connection terminal body 201 through the first limiting opening 701. Moreover, the end of the first support column 70 is also provided with an arc surface 702 that matches the surface of the electrical connection terminal body 201. After the two housing units 10a are spliced, the first support columns 70 on both sides of the electrical connection terminal body 201 can clamp and fix the electrical connection terminal body 201 through the arc surface 702.

[0042] Furthermore, a second support column 80 is provided on the inner wall of the electrical connection part 104, and two clamping plates 801 are connected to the second support column 80, and a second limiting opening 802 is formed between the two clamping plates 801. A limiting portion 205 is provided on the outer side of the electrical connection terminal body 201. When the two housing units 10a are spliced, the second support columns 80 on both sides of the electrical connection terminal body 201 are engaged with the limiting portion 205 through the second limiting opening 802.

[0043] In actual design, the clamping member on the inner wall of the electrical connection part 104 can be any one of the first support column 70 and the second support column 80, or a combination of the first support column 70 and the second support column 80. The purpose of providing the first support column 70 and the second support column 80 is mainly to clamp and fix the electrical connection terminal body 21 to ensure the stability of the electrical connection terminal assembly 20 in the inner cavity 105 of the electrical connection part 104.

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.
