Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a heat-dissipating air model fan. Background Art

[0002] With the popularization and improvement of public entertainment facilities, especially inflatable play facilities are the most common, such as inflatable castles. An inflatable castle usually includes an air model and an air model fan for blowing air into the air model body.

[0003] The existing air model fan specifically includes a housing, a motor, and an impeller; the housing has an air inlet and an air outlet; the motor and the impeller are both installed inside the housing, and the impeller is installed at the power output end of the motor; when the motor is started, the output shaft of the motor drives the impeller to rotate, thereby driving the gas to move and output from the air outlet for inflating the air model.

[0004] Currently, during the use of the existing air model fan, a single-shaft motor is generally adopted. The air inlet is located on the front of the housing, the air outlet is located on the side of the housing, and heat dissipation holes are provided on the back of the housing. However, simply using the heat dissipation holes for heat dissipation has poor heat dissipation effect, making the heat generated by the motor easily accumulate in the cavity at the rear half of the motor. In the long run, it will affect the service life of the motor; for this reason, we propose a heat-dissipating air model fan. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a heat-dissipating air model fan, which can effectively solve the problems raised in the above background art after improvement.

[0006] The technical solution of the utility model is as follows:

[0007] A heat-dissipating air model fan includes a housing and a driving motor; the driving motor is installed inside the housing, and the driving motor is provided with a first power output end and a second power output end. The driving motor is connected with a first impeller through the first power output end, and the driving motor is connected with a second impeller through the second power output end. A first air cavity and a second air cavity are arranged inside the housing, and the first impeller and the second impeller are respectively located inside the first air cavity and the second air cavity, and the first air cavity and the second air cavity are communicated; a first air inlet and a second air inlet are respectively arranged on the front and back of the housing, and an air outlet is arranged on the side of the housing, and the air outlet is communicated with the first air inlet.

[0008] Further, the driving motor is a double-shaft motor.

[0009] Further, gratings are arranged on the first air inlet, the second air inlet, and the air outlet.

[0010] Furthermore, a cooling chamber is provided inside the outer shell. A cooling pipe is installed inside the cooling chamber. The second air chamber is in communication with the cooling chamber, and the cooling chamber is in communication with the first air chamber.

[0011] Furthermore, both ends of the cooling pipe are respectively connected to a water inlet pipe and a water outlet pipe, and the water inlet pipe and the water outlet pipe are connected to the outer shell in a communicating manner.

[0012] Furthermore, the first impeller and the second impeller have the same structure. The first impeller includes a connecting shell, blades, and an annular clamping strip. One end of the connecting shell close to the driving motor is a concave structure. An axial hole is provided in the middle of the connecting shell. The driving motor is fixedly connected to the connecting shell through a rotating shaft. An annular clamping strip is fixedly connected to the side of the connecting shell, and a plurality of blades are fixedly installed on the annular clamping strip. The plurality of blades are arranged at equal intervals.

[0013] Furthermore, an installation shell is fixedly installed inside the outer shell and within the first air chamber. The installation shell encloses to form the cooling chamber. The installation shell is respectively provided with a first ventilation hole and a second ventilation hole. The first ventilation hole is in communication with the second air chamber, and the second ventilation hole is in communication with the first air chamber.

[0014] The beneficial effects of the present utility model are as follows:

[0015] Compared with the prior art, the present utility model is provided with a first impeller, a second impeller, a first air chamber, and a second air chamber. Air can enter from the first air inlet and the second air inlet. The entered gas can dissipate heat from both ends of the motor. After heat exchange, the gas can finally be discharged through the air outlet, thereby achieving a better heat dissipation effect. At the same time, air enters from both ends of the outer shell, then passes through the first air chamber and the second air chamber respectively, and finally converges and is discharged from the air outlet, which can greatly enhance the air volume, form a strong air volume, and better meet the needs of inflating the air model. In addition, a cooling chamber and a cooling pipe are also provided, which can perform heat exchange on the gas that has undergone heat exchange in the second air chamber, thereby reducing the temperature of the gas. The low-temperature gas can also be mixed with the gas that has undergone heat exchange in the first air chamber, so that the gas can reach room temperature or a temperature lower than room temperature. According to the gas temperature requirements of the air model, gases of different temperatures can be filled, thereby expanding the usage range of the air model blower and improving the usage effect of the air model blower, and the practicability is relatively strong.

[0024] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings:

[0025] As Figure 1-7 shown,

[0026] A heat-dissipating air model blower includes an outer shell 1 and a driving motor 2; the driving motor 2 is installed inside the outer shell 1, the driving motor 2 is provided with a first power output end and a second power output end, the driving motor 2 is connected to a first impeller 3 through the first power output end, the driving motor 2 is connected to a second impeller 4 through the second power output end, a first air chamber 5 and a second air chamber 6 are arranged inside the outer shell 1, the first impeller 3 and the second impeller 4 are respectively located inside the first air chamber 5 and the second air chamber 6, and the first air chamber 5 and the second air chamber 6 are communicated; a first air inlet 7 and a second air inlet 8 are respectively arranged on the front and back of the outer shell 1, an air outlet 9 is arranged on the side of the outer shell 1, and the air outlet 9 is communicated with the first air inlet 7; in this embodiment, two air inlets are arranged, so that the drawn natural wind can effectively reduce the temperature inside the blower, achieving a better heat dissipation effect for the driving motor 2 (natural wind enters both ends of the driving motor 2 for heat dissipation, and compared with setting heat dissipation holes, the heat dissipation effect of the present utility model is better), and moreover, in the traditional technology, there is only one air inlet, and the incoming gas is difficult to form a strong air volume, thus it is difficult to meet the requirements of an air model that needs a strong air volume, while the present application can achieve a strong air volume.

[0027] As a preferred embodiment, the drive motor 2 is a dual-axis motor. By using a dual-axis motor, which has two output ends, it can form a two-way air extraction.

[0028] As a preferred embodiment, grilles 10 are provided on the first air inlet 7, the second air inlet 8, and the air outlet 9. By providing the grilles 10 (the grilles 10 can have different shapes), it can effectively filter some larger particulate impurities, thereby improving the gas quality of the air mold fan.

[0029] As a preferred embodiment, a cooling chamber 11 is further provided inside the housing 1. A cooling pipe 12 is installed inside the cooling chamber 11. The second air chamber 6 communicates with the cooling chamber 11, and the cooling chamber 11 communicates with the first air chamber 5. It can be understood that by providing the cooling chamber 11 and the cooling pipe 12, the gas that has undergone heat exchange in the second air chamber 6 can be further heat-exchanged, thereby reducing the temperature of this part of the gas. When this part of the low-temperature gas is discharged into the first air chamber 5, it can also be mixed with the gas that has undergone heat exchange in the first air chamber 5 (higher than normal temperature), so that the gas can reach normal temperature or a temperature lower than normal temperature and then be discharged through the air outlet 9. According to the gas temperature requirements of the air mold, gases of different temperatures can be filled, thereby expanding the usage range of the air mold fan and improving the usage effect of the air mold fan. More specifically, the temperature of the water inside the cooling pipe 12 can be adjusted (cold water of different temperatures can be introduced), and then the heat exchange temperature of the gas can be adjusted to make the gas temperature reach a controllable state.

[0030] As a preferred embodiment, both ends of the cooling pipe 12 are respectively connected to a water inlet pipe 13 and a water outlet pipe 14, and the water inlet pipe 13 and the water outlet pipe 14 are connected to the housing 1. It can be understood that the cooling pipe 12 mainly passes cold water (low-temperature liquids or low-temperature gases such as liquid nitrogen can also be passed). When low-temperature gases are input, air inlet pipes and air outlet pipes can be used. In addition, the cooling pipe 12 can be made of stainless steel.

[0031] As a preferred embodiment, the first impeller 3 and the second impeller 4 have the same structure. The first impeller 3 includes a connecting shell 15, blades 16, and an annular clamping strip 17. One end of the connecting shell 15 close to the drive motor 2 is a concave structure. An axial center hole 18 is provided in the middle of the connecting shell 15. The drive motor 2 is fixedly connected to the connecting shell 15 through a rotating shaft. An annular clamping strip 17 is fixedly connected to the side of the connecting shell 15, and a plurality of blades 16 are fixedly installed on the annular clamping strip 17. The plurality of blades 16 are arranged at equal intervals. It can be understood that one end of the connecting shell 15 close to the drive motor 2 is a concave structure, so that a part of both ends of the drive motor 2 can enter the inside of the connecting shell 15, thereby greatly reducing the volume of the entire housing 1 and reducing the packaging cost and logistics cost.

[0032] As a preferred embodiment, an installation shell 19 is fixedly installed inside the outer shell 1 and inside the first air chamber 5. The installation shell 19 encloses to form a cooling chamber 11. A first ventilation hole 20 and a second ventilation hole 21 are respectively arranged on the installation shell 19. The first ventilation hole 20 communicates with the second air chamber 6, and the second ventilation hole 21 communicates with the first air chamber 5. By providing the installation shell 19, the first ventilation hole 20 and the second ventilation hole 21, not only can the first air chamber 5 and the second air chamber 6 be communicated, but also heat exchange of the gas can be realized, and the output temperature of the gas can be controlled to meet the requirements of different types of inflatables for the gas temperature.

[0033] The working principle of the present utility model is as follows: During operation, the driving motor 2 is first started. The driving motor 2 drives the first impeller 3 and the second impeller 4 to rotate respectively for double-sided air extraction. The gas enters into the first air chamber 5 and the second air chamber 6 respectively. During this process, the driving motor 2 can be cooled. The gas in the second air chamber 6 enters into the cooling chamber 11 under the action of air pressure (entering through the first ventilation hole 20), and heat exchange is carried out by the cooling pipe 12. Then the gas will enter into the first air chamber 5 (entering through the second ventilation hole 21), be mixed with the gas inside the first air chamber 5, and finally be discharged into the inflatable through the air outlet 9.

[0034] It should be pointed out that the main problem in the prior art is that: simply using heat dissipation holes for heat dissipation has poor heat dissipation effect, making the heat generated by the motor easily accumulate in the cavity at the rear half of the motor. If this continues for a long time, it will affect the service life of the motor.

[0035] Therefore, after the improvement of this application, air can enter from the first air inlet 7 and the second air inlet 8. The entering gas can cool both ends of the driving motor 2. After heat exchange, the gas can finally be discharged through the air outlet 9, thereby achieving a better heat dissipation effect.

[0036] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary engineering and technical personnel in the art to the technical solution of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
