Description

Technical Field

[0002] Turbine fans can be used in bladeless blowers, air purifiers, electric heaters and other products. Turbine fans usually include a bracket and a housing mounted on the bracket. A turbine assembly is arranged in the housing. The turbine assembly includes a motor and blades. When the turbine fan is in use, the motor can drive the blades to rotate. Since the rotation of the blades will generate large vibrations, the vibrations will cause large noises, affecting the user experience.

[0003] The turbine fans on the market generally use tension springs to achieve the shock absorption effect. During installation, six tension springs are connected to the turbine assembly, three at the top and three at the bottom, and then the other ends of the six tension springs are connected to the bracket, so that the entire turbine assembly is suspended in the air, thereby achieving the effect of shock absorption and noise reduction. However, although this structure can achieve the effect of shock absorption and noise reduction, it requires fixing the upper and lower ends of the turbine assembly at the same time, the structure is relatively complex, and the installation process is relatively cumbersome, resulting in low installation efficiency of the turbine fan.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figures 1 to 5 One embodiment of the utility model provides a turbine blower, which includes a bracket 100, a shell 110 and three sets of elastic supporting mechanisms. The shell 100 is located above the bracket 100, and a turbine assembly 120 is installed in the shell 110. The three sets of elastic supporting mechanisms are arranged between the bracket 100 and the shell 110, and all the elastic supporting mechanisms are arranged at intervals around the circumference of the shell 110. The upper end of the elastic supporting mechanism abuts against the shell 110, and the lower end of the elastic supporting mechanism abuts against the shell 100. Among them, the shell 110 is floatingly installed above the bracket 100 through the elastic supporting mechanism.

[0034] In the above structure, three sets of elastic supporting mechanisms are arranged between the shell 110 and the bracket 100, and the upper end of the elastic supporting mechanism is in contact with the shell 110, and the lower end of the elastic supporting mechanism is in contact with the shell 100, so that the elastic supporting mechanism can play a role in supporting the shell 110. When the turbine fan is working, it is easy to vibrate. Since the elastic supporting mechanism is elastic, the shell 110 is installed floatingly above the bracket 100, thereby achieving the effect of buffering and shock absorption, reducing the noise generated by the turbine fan, and improving the user's experience. In this structure, the shell 110 is installed floatingly above the bracket 100 through the elastic shock absorbing mechanism, which not only can achieve the effect of shock absorption and noise reduction, but also has a simple structure and is easy to install, thereby improving the installation efficiency of the turbine fan.

[0035] It can be understood that a turbine assembly 120 is installed inside the housing 110 . The turbine assembly 120 specifically includes a motor and turbine blades. The motor is transmission-connected to the turbine blades and can drive the turbine blades to rotate.

[0036] It is understandable that the number of the above elastic supporting mechanisms is 3 groups, which is only for Figures 1 to 5 The number of the elastic supporting mechanisms may be 3 groups, 2 groups, 4 groups, 5 groups or even more groups, and the present invention does not specifically limit this. It is only necessary to ensure that all the elastic supporting mechanisms are arranged at intervals along the circumference of the housing 110.

[0037] It is understandable that the upper end of the elastic support mechanism abuts against the housing 110, and the lower end of the elastic support mechanism abuts against the bracket 100, which is only for Figures 1 to 5 In addition, the lower end of the elastic support mechanism can also be connected to the bracket 100, and the upper end of the elastic support mechanism can be abutted against the shell 110. In this way, the installation stability of the elastic support mechanism can be improved, and the elastic support mechanism can be prevented from being separated from the shell 110 and the bracket 100 during the use of the turbo fan, resulting in a collision between the shell 110 and the bracket 100 and causing damage.

[0038] It is understandable that, in order to ensure the installation stability of the elastic supporting mechanism, in addition to connecting the lower end of the elastic supporting mechanism to the bracket 100 and the upper end of the elastic supporting mechanism to the housing 110, the upper end of the elastic supporting mechanism can also be connected to the housing 110 and the lower end of the elastic supporting mechanism can also be connected to the bracket 100. Alternatively, the upper end of the elastic supporting mechanism can also be connected to the housing 110 and the lower end of the elastic supporting mechanism can be connected to the bracket 100, and the utility model does not specifically limit this.

[0039] Reference Figures 1 to 5In some embodiments, each set of elastic supporting mechanisms includes a positioning structure disposed between the bracket 100 and the housing 110 and an elastic shock absorbing member 130 mounted on the positioning structure. All positioning structures are arranged at intervals around the circumference of the housing 110. The upper end of the elastic shock absorbing member 130 abuts against the housing 110, and the lower end of the elastic shock absorbing member 130 abuts against the bracket 100.

[0040] In the above structure, the positioning structure can facilitate the positioning and installation of the elastic shock absorbing member 130. The elastic shock absorbing member 130 is installed on the positioning structure, and the upper end is abutted against the shell 110, and the lower end is abutted against the bracket 100. Therefore, the elastic shock absorbing member 130 can play a role in supporting the shell 110, so that the shell 110 is installed floatingly above the bracket 100, thereby achieving the effect of buffering and shock reduction, reducing the noise generated by the turbo fan, and improving the user's experience. In this structure, the shell 110 is installed floatingly above the bracket 100 through the elastic shock absorbing member 130, which can not only achieve the effect of shock reduction and noise reduction, but also has a simple structure and is easy to install, thereby improving the installation efficiency of the turbo fan.

[0041] It is understandable that the upper end of the elastic damping member 130 abuts against the housing 110, and the lower end of the elastic damping member 130 abuts against the bracket 100, which is only for Figures 1 to 5 In addition, the lower end of the elastic shock absorber 130 can also be connected to the bracket 100, and the upper end of the elastic shock absorber 130 can be abutted against the shell 110. In this way, the installation stability of the elastic shock absorber 130 can be improved, and the elastic shock absorber 130 can be prevented from being separated from the shell 110 and the bracket 100 during use, resulting in a collision between the shell 110 and the bracket 100 and causing damage.

[0042] It is understandable that, in order to ensure the installation stability of the elastic shock absorbing member 130, in addition to connecting the lower end of the elastic shock absorbing member 130 to the bracket 100 and the upper end of the elastic shock absorbing member 130 to the housing 110, the upper end of the elastic shock absorbing member 130 can also be connected to the housing 110 and the lower end of the elastic shock absorbing member 130 can also be connected to the bracket 100. Alternatively, the upper end of the elastic shock absorbing member 130 can also be connected to the housing 110 and the lower end of the elastic shock absorbing member 130 can be connected to the bracket 100, and the utility model does not specifically limit this.

[0043] It is understandable that each set of the elastic supporting mechanism includes a positioning structure disposed between the bracket 100 and the housing 110 and an elastic shock absorbing member 130 installed on the positioning structure. Figures 1 to 5In addition, each set of elastic supporting mechanisms may also only include an elastic shock absorbing member 130, the upper end of the elastic shock absorbing member 130 is connected or abutted with the housing 110, and the lower end of the elastic shock absorbing member 130 is connected or abutted with the bracket 100. Thus, the elastic shock absorbing member 130 can play a role in supporting the housing 110, so that the housing 110 is floatingly installed above the bracket 100, thereby achieving the effect of shock reduction and noise reduction, with a simple structure and convenient installation, which can improve the installation efficiency of the turbo fan.

[0044] It is understandable that, referring to Figures 1 to 4 In some embodiments, the elastic shock absorbing member 130 may be a compression spring. The compression spring can withstand a large pressure and has good elasticity and expansion performance. The compression elastic spring is installed on the corresponding positioning structure, and the upper end of the compression spring is abutted against the housing 110, and the lower end is abutted against the bracket 100, so as to achieve a good shock absorbing effect and provide better support for the housing 110.

[0045] It is understandable that, in addition to the compression spring, the elastic shock absorbing member 130 may also be made of silicone, rubber or other elastic components that can perform buffering and shock absorbing functions, and the present invention does not make any specific limitation on this.

[0046] Reference Figures 1 to 4 In some embodiments, each set of positioning structures includes a first positioning portion provided on the bracket 100, and the elastic shock absorbing member 130 is installed on the first positioning portion.

[0047] By setting a first positioning portion on the bracket 100 and installing the elastic shock absorber 130 on the first positioning portion, the elastic shock absorber 130 can be installed on the bracket 100 through the first positioning portion, and the upper end of the elastic shock absorber 130 is abutted or connected to the shell 110, so that the elastic shock absorber 130 can play a role in supporting the shell 110, so that the shell 110 is floatingly installed above the bracket 100, with a simple structure and easy installation.

[0048] It is understandable that in order to facilitate the production and processing of the bracket 100 and the first positioning portion, the first positioning portion and the bracket 100 can be integrally formed.

[0049] Reference Figures 1 to 4 In some embodiments, the first positioning portion defines a first positioning groove 140 opening toward the housing 110 , and the elastic shock absorbing member 130 is at least partially located in the first positioning groove 140 .

[0050] In the above structure, the setting of the first positioning groove 140 can facilitate the positioning and installation of the elastic shock absorber 130. During installation, the elastic shock absorber 130 only needs to be placed in the first positioning groove 140. The structure is simple and easy to install, thereby improving the installation efficiency of the turbine blower.

[0051] It is understandable that the first positioning portion is provided with a first positioning groove 140 opening toward the housing 110, which is only for Figures 1 to 4 In addition, the first positioning portion may also adopt other structures.

[0052] For example, in some embodiments, the first positioning portion can be a first positioning column disposed on the bracket 100, and the elastic shock absorbing member 130 is at least partially sleeved on the outer periphery of the first positioning column. The provision of the first positioning column can facilitate the positioning and installation of the elastic shock absorbing member 130. During installation, it is only necessary to sleeve the elastic shock absorbing member 130 on the outer periphery of the first positioning column. The structure is simple and the installation is convenient, thereby improving the installation efficiency of the turbo blower.

[0053] Reference Figures 1 to 5 In some embodiments, each group of positioning structures includes a second positioning portion provided on the housing 110 , and the elastic shock absorbing member 130 is installed on the second positioning portion.

[0054] By setting a second positioning portion on the shell 110 and installing the elastic shock absorber 130 on the second positioning portion, the elastic shock absorber 130 can be installed on the shell 110 through the second positioning portion, and the lower end of the elastic shock absorber 130 is abutted or connected to the bracket 100, so that the elastic shock absorber 130 can play a role in supporting the shell 110, so that the shell 110 is floatingly installed above the bracket 100, thereby achieving the effect of shock absorption and noise reduction, and the structure is simple and easy to install.

[0055] It is understandable that in order to facilitate the production and processing of the shell 110 and the second positioning portion, the second positioning portion and the shell 110 can be integrally formed.

[0056] Reference Figures 1 to 5 In some embodiments, the second positioning portion is a second positioning column 150 disposed on the housing 110 , and the elastic shock absorbing member 130 is at least partially sleeved on the outer periphery of the second positioning column 150 .

[0057] In the above structure, the second positioning column 150 can facilitate the positioning and installation of the elastic damping member 130. During installation, the elastic damping member 130 only needs to be sleeved on the outer periphery of the second positioning column 150, which has a simple structure and is easy to install, thereby improving the installation efficiency of the turbo fan.

[0058] It is understandable that the second positioning portion is a second positioning column 150 disposed on the housing 110, which is only for Figures 1 to 5 In addition, the second positioning portion may also adopt other structures.

[0059] For example, in some embodiments, the second positioning portion is provided with a second positioning groove with an opening toward the bracket 100, and the elastic shock absorbing member 130 is at least partially located in the second positioning groove. The provision of the second positioning groove can facilitate the positioning and installation of the elastic shock absorbing member 130. During installation, it is only necessary to place the elastic shock absorbing member 130 in the second positioning groove, which has a simple structure and is easy to install, thereby improving the installation efficiency of the turbo blower.

[0060] It is understandable that each set of positioning structures may include a first positioning portion provided on the bracket 100 or a second positioning portion provided on the housing 110. Figures 1 to 5 Each group of positioning structures may also include a first positioning portion and a second positioning portion at the same time, and the present invention does not make any specific limitation on this.

[0061] Reference Figures 1 to 5 In some embodiments, the number of the elastic supporting mechanisms is three groups, and all the elastic supporting mechanisms are evenly arranged along the circumference of the housing 110. The upper ends of the elastic supporting mechanisms are inclined toward the central axis of the housing 110, and the inclination angles of all the elastic supporting mechanisms are the same.

[0062] In the above structure, three groups of elastic supporting mechanisms are evenly arranged along the circumference of the shell 110, and the upper ends of the elastic supporting mechanisms are tilted toward the central axis of the shell 110 and the tilt angles of all the elastic supporting mechanisms are the same. As a result, the three groups of elastic supporting mechanisms can cooperate with each other to support the shell 110 in the vertical direction and center the shell 110 in the horizontal direction. When the shell 110 shakes relative to the bracket 100 and deviates from the center of the bracket 100, the three groups of elastic supporting mechanisms can cooperate to reset the shell 110 to the center, and then the shell 110 can be located as close to the center of the bracket 100 as possible, thereby reducing the vibration of the turbine fan.

[0063] It is understandable that the number of the above elastic supporting mechanisms is three, which is only for Figures 1 to 5 In order to make the shell 110 as close to the center of the bracket 100 as possible, the number of the elastic supporting mechanisms may be three, four, five or more groups, and the utility model does not make any specific limitation on this, and it is only necessary to ensure that all the elastic supporting mechanisms are evenly arranged along the circumference of the shell 110.

[0064] It can be understood that when each group of elastic supporting mechanisms includes a positioning structure provided between the bracket 100 and the shell 110 and an elastic shock absorber 130 installed on the positioning structure, all the positioning structures are evenly arranged around the circumference of the shell 110, the upper end of the elastic shock absorber 130 is connected or abutted with the shell 110, the lower end of the elastic shock absorber 130 is connected or abutted with the bracket 100, and the upper end of the elastic shock absorber 130 is inclined toward the central axis of the shell 110, and the inclination angles of all the elastic shock absorbers 130 are the same.

[0065] Thus, all the elastic dampers 130 can cooperate with each other to support the housing 110 in the vertical direction and center the housing 110 in the horizontal direction. When the housing 110 shakes relative to the bracket 100 and deviates from the center of the bracket 100, all the elastic dampers 130 can cooperate to restore the housing 110 to the center, thereby making the housing 110 as close to the center of the bracket 100 as possible, thereby reducing the vibration of the turbo fan.

[0066] It is understandable that, in order to make the housing 110 as close to the center of the bracket 100 as possible, when the positioning structure includes a first positioning portion provided on the bracket 100, the first positioning portion can be arranged to be tilted upward, and the free end of the first positioning portion is directed toward the housing 110. In this way, the elastic shock absorbing member 130 can be guided to be arranged to be tilted relative to the bracket 100, so that the upper end of the elastic shock absorbing member 130 is tilted toward the central axis of the housing 110, and then all the elastic shock absorbing members 130 can cooperate with each other to support the housing 110 in the vertical direction and center the housing 110 in the horizontal direction.

[0067] Further, when the first positioning portion is provided with a first positioning groove 140, the first positioning groove 140 can be tilted toward the housing 110, and the elastic shock absorbing member 130 can be at least partially located in the first positioning groove 140. Alternatively, when the first positioning portion is a first positioning column provided on the bracket 100, the first positioning column can be tilted toward the center of the housing 110, and the elastic shock absorbing member 130 can be at least partially sleeved on the outer periphery of the first positioning column.

[0068] It is understandable that, in order to make the housing 110 as close to the center of the bracket 100 as possible, when the positioning structure includes a second positioning portion provided on the housing 110, the second positioning portion can be tilted downward, and the free end of the second positioning portion is directed toward the bracket 100. In this way, the elastic damping member 130 can be guided to be tilted relative to the bracket 100, so that the upper end of the elastic damping member 130 is tilted toward the central axis of the housing 110, and all the elastic damping members 130 can cooperate with each other to support the housing 110 in the vertical direction and center the housing 110 in the horizontal direction.

[0069] Furthermore, when the second positioning portion is provided with a second positioning groove, the second positioning groove can be tilted toward the bracket 100, and the elastic shock absorbing member 130 is at least partially located in the second positioning groove. Alternatively, when the first positioning portion is a second positioning column 150 provided on the housing 110, the second positioning column 150 can be tilted toward the bracket, and the elastic shock absorbing member 130 is at least partially sleeved on the outer periphery of the second positioning column 150.

[0070] Reference Figures 1 to 5 In some embodiments, at least one set of guide structures is provided between the housing 110 and the bracket 100, each set of guide structures includes a first guide portion 160 and a second guide portion 170 that cooperate with each other, and the first guide portion and the second guide portion can cooperate to guide the housing 110 to reciprocate in the up and down directions relative to the bracket 100. The first guide portion 160 is provided on the bracket 100, and the second guide portion 170 is provided on the housing 110.

[0071] In the above structure, since the turbine fan may generate large vibrations when in use, by setting a first guide portion 160 and a second guide portion 170 between the shell 110 and the bracket 100, the first guide portion 160 and the second guide portion 170 can cooperate to guide the shell 110 to reciprocate in the up and down directions relative to the bracket 100, that is, they can cooperate to limit the vibration of the shell 110 in the up and down directions relative to the bracket 100, thereby preventing the shell 110 from deviating from the central axis of the bracket 100 during the vibration process, and further allowing the shell 110 to be located as far as possible in the center of the bracket 100.

[0072] Reference Figures 1 to 5 In some embodiments, the first guide portion 160 is a guide column disposed on the bracket 100 and arranged in the up-down direction, the second guide portion 170 is disposed on the housing 110, and the second guide portion 170 is provided with a guide hole 171 that is plugged with the guide portion, and the second guide portion 170 can reciprocate along the axial direction of the guide column. A fastener that can abut against the second guide portion 170 is installed at the free end of the guide column.

[0073] In the above structure, when vibration occurs between the housing 110 and the bracket 100, the second guide portion 170 can reciprocate along the axial direction of the guide column. Since the guide column is arranged in the up-down direction, when the turbo fan vibrates, the housing 110 can move in the up-down direction relative to the bracket 100, thereby preventing the housing 110 from deviating from the central axis of the bracket 100 during the vibration process, and thus making the housing 110 as close to the center of the bracket 100 as possible. The provision of the fastener can prevent the second guide portion 170 from escaping from the free end of the guide column when moving along the axial direction of the guide column, thereby limiting the movement stroke of the housing 110 in the up-down direction, and preventing the housing 110 and the bracket 100 from being separated from each other during the vibration process, which affects the normal use of the turbo fan.

[0074] It is understandable that the first guide portion 160 is provided on the bracket 100, and the second guide portion 170 is provided on the housing 110. Figures 1 to 5 In addition, the first guide portion 160 may be disposed on the housing 110 and the second guide portion 170 may be disposed on the bracket 100, and the present invention does not specifically limit this.

[0075] It is understandable that the free end of the guide column is installed with a fastener that can abut against the second guide portion 170. When the guide column is set on the bracket 100, the free end of the guide column specifically refers to the end of the guide column away from the bracket 100. When the guide column is set on the housing 110, the free end of the guide column specifically refers to the end of the guide column away from the housing 110.

[0076] It is understandable that the fastener may be a nut threadedly connected to the guide post, or may be a clamping structure clamped to the guide post, and the present invention does not make any specific limitation on this.
