Description

Technical Field

[0001] The utility model belongs to the technical field of fireplace fans, in particular to a wall-mounted fireplace fan. Background Art

[0002] A fireplace is an indoor heating device that is independent or built into a wall. Currently used fireplaces all need to be equipped with a fireplace fan to spread the heat generated by the fireplace to various locations in the room so that the heat in the room is evenly distributed.

[0003] In the related technology, reference can be made to the Chinese utility model patent with the authorization announcement number CN219452452U, which specifically discloses a wall-mounted fireplace fan, which relates to the field of fireplace fan technology. The magnetic block on the inner side of the bracket seat can be used to install the fireplace fan on the outer side of the fireplace, and the pressing slider can be used to limit the connection ratchet wheel through the positioning arc plate, so that the fan structure and the connection base can be adjusted in an adaptive angle. While ensuring that the fireplace fan can normally diffuse the heat of the fireplace, the fireplace fan can also be installed on the outer wall of the fireplace and the fireplace smoke pipe in a wall-mounted form, thereby increasing the application range of the fireplace fan.

[0004] The applicant found that the above mainly uses magnetic attraction to achieve the wall-mounted operation of the fan, but there are still some fireplaces that are made of glass or marble, which makes it impossible for the above fans to be wall-mounted on the fireplace, resulting in still some limitations. Utility Model Content

[0005] The purpose of the utility model is to provide a wall-mounted fireplace fan in order to solve the above-mentioned problem.

[0006] The technical solution adopted by the utility model is as follows: a wall-mounted fireplace fan, comprising a base and a fan arranged on the base, the back side of the base is recessed inward to form a concave surface that can be attached to the fireplace pipe, a plurality of air holes are evenly arranged on the back side and the concave surface of the base, a vacuum chamber is provided inside the base, which is respectively connected to the back side of the base and the concave air holes, an air suction piece is provided on the upper end surface of the base, and a gas channel connected to the air suction piece and the vacuum chamber is provided inside the base.

[0007] In a preferred embodiment, a one-way gas valve is provided at the connection between the gas channel and the gas extraction member, and the gas extraction member is a gas extraction cylinder.

[0008] In a preferred embodiment, a three-way valve and a ventilation valve are provided on the gas channel, and the other two interfaces of the three-way valve are respectively connected to the two vacuum chambers.

[0009] In a preferred embodiment, the fan is provided with a protective cover with ventilation holes, and a connecting arm is installed on the back side of the protective cover.

[0010] In a preferred embodiment, a mounting frame is provided on the base, a support arm is rotatably mounted in the mounting frame via a rotating shaft, and an upper end portion of the support arm is directly rotatably mounted together with the connecting arm via a second rotating shaft.

[0011] In a preferred embodiment, the valve stems of the ventilation valve and the three-way valve extend outside the base.

[0012] In summary, due to the adoption of the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: vacuuming is adopted as a whole to realize the fixing operation, and the plane and concave surface which are vacuum adsorbed on the fireplace and the fireplace pipe are correspondingly designed on the base. When wall-mounted fixing is required, the vacuuming cavity of the plane or concave surface is evacuated into a vacuum by using a vacuum piece. At this time, the vacuum can be used to adsorb it on the desired position. It can be used for fireplaces of different materials and has stronger applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Reference Figure 1-3A wall-mounted fireplace fan comprises a base 7 and a fan 1 arranged on the base 7. The back of the base 7 is recessed inward to form a concave surface 8 that can be attached to the fireplace pipe. A plurality of air holes 9 are evenly opened on the back of the base 7 and the concave surface 8. The base 7 has a vacuum chamber 11 connected with the back of the base 7 and the air holes 9 on the concave surface 8 respectively. The upper end surface of the base 7 is provided with a suction piece 4. The base 7 is provided with a gas channel 10 connected with the suction piece 4 and the vacuum chamber 11. The overall fixing operation is achieved by vacuuming. The base 7 is correspondingly designed with a plane and a concave surface 8 that are vacuum-adsorbed on the fireplace and the fireplace pipe (not shown in the figure). When wall-mounted fixing is required, the vacuum chamber 11 of the plane or concave surface 8 is correspondingly evacuated by the suction piece 4. At this time, it can be adsorbed on the desired position by vacuum. It can be used for fireplaces of different materials and has stronger applicability.

[0019] The designed base 7 can also satisfy the requirement of directly placing the fan 1 on the fireplace.

[0020] Furthermore, a one-way air valve 12 is provided at the connection between the gas channel 10 and the vacuum component 4. The vacuum component 4 is a vacuum cylinder. The direction of the one-way air valve 12 is from inside to outside. The one-way air valve 12 is used to prevent the gas from returning to the vacuum chamber 11 and affecting the vacuum adsorption operation.

[0021] Among them, the vacuum pump is a commonly used equipment, and the specific structure will not be elaborated here one by one.

[0022] Furthermore, a three-way valve 6 and a ventilation valve 5 are provided on the gas channel 10, and the other two interfaces of the three-way valve 6 are respectively connected to the two vacuum chambers 11. When the whole needs to be taken out from the fireplace, the ventilation valve 5 can be opened. At this time, the vacuum chamber 11 is in a connected state with the outside world, thereby releasing the vacuum state, so that the fan can be directly taken out of the fireplace. The corresponding vacuum position can be selected through the three-way valve 6, and the fixing operation of the fireplace pipe or the fireplace itself can be realized according to actual needs.

[0023] Furthermore, the fan 1 has a protective cover with ventilation holes, a connecting arm 101 is installed on the back of the protective cover, a mounting frame 3 is provided on the base 7, a support arm 2 is rotatably installed in the mounting frame 3 through a rotating shaft member 13, and the upper end of the support arm 2 is directly rotatably installed together with the connecting arm 101 through a second rotating shaft member. The above design can adjust the position and angle of the fan 1 accordingly.

[0024] The rotating shaft 13 is a damping rotating shaft.

[0025] It should be mentioned that the fan 1 is a commonly used device and its specific structure will not be described here.

[0026] Furthermore, the valve stems of the ventilation valve 5 and the three-way valve 6 extend outside the base 7. The above design facilitates the user to adjust the ventilation state and the switching state of the vacuum position.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
