[0018] The present invention proposes a tower fan having an emergency stop structure.

[0019] In an embodiment of the present invention, as illustrated in FIGS. 1 to 5, a tower fan having an emergency stop structure comprising a front housing (1), a rear housing (7), a rear mesh (5) snap-coupled to the rear housing (7), and a blower fan (2) embedded in the front housing (1) further comprises an elastic pressurizing member (4) and a stop assembly (3). The stop assembly (3) is mounted on the rear housing (7). The stop assembly (3) comprises a push rod (31) positioned to be movable in the vertical direction, a push block (32) having an inclined surface formed on the left and a right side in contact with the rear mesh (5), and a gasket (33) mounted on the lower end of the push block (32). The push rod (31) is positioned in contact with the inclined surface of the push block (32). One end of the elastic pressurizing member (4) contacts the push rod (31) and the other end contacts the top of the rear housing (7), thereby [contacting] the push rod (31). Pressurizing is applied downward. Due to the elastic force of the elastic pressurizing member (4), the push rod (31) comes into contact with the inclined surface of the push block (32). When the rear mesh (5) in contact with the right side of the push block (32) is removed, the push rod (31) moves downward due to the elastic force of the elastic pressurizing member (4), moving the push block (32) to the right. At the same time, as the push rod (31) descends further, the gasket (33) mounted on the lower end of the push rod (31) comes into contact with the rotating blower fan (2), thereby restricting the rotation of the blower fan (2).

[0020] One end of the elastic pressure member (4) contacts the upper part of the push rod (31) and the other end contacts the upper part of the rear housing (7). At this time, the elastic pressure member (4) is in a compressed state. When the rear mesh (5) is removed from the rear housing (7), the push rod (31) is pushed downward by the elasticity of the elastic pressure member (4), and the gasket (33) mounted on the bottom of the push rod (31) comes into contact with the rotating blower fan (2), thereby restricting the rotation of the blower fan (2) and causing the blower fan (2) to stop in an emergency.

[0021] In this embodiment, the push block (32) includes a sliding slope (34), and the sliding slope (34) includes two side plates (341) installed at an angle, and the two side plates (341) surround to form a placement groove (35). The push rod (31) contacts the inclined surface of the side plate (341), and the lower end of the push rod (31) equipped with the gasket (33) is placed within the placement groove (35). The purpose of designing the placement groove (35) is to prevent the push block (32) from moving outward and the push rod (31) from moving downward.

[0022] In this embodiment, a contact plate (36) extending left and right is installed at one end far from the side plate (341), and the contact plate (36) surrounds to form an avoidance groove (37).

[0023] In this embodiment, a push rib piece (51) is mounted on the rear mesh (5), and the position of the push rib piece (51) corresponds to the contact plate (36). When the rear mesh (5), which was separated, is mounted on the rear housing (7), the push rib piece (51) pushes the push block (32) to cause the side plate (341) to move horizontally to the left, and at the same time, the push rod (31) moves upward again along the inclined surface formed on the push block (32). After mounting the rear mesh (5) on the rear housing (7), the push block (32) is pushed through the rear mesh (5), and the push block (32) pushes the push rod (31) to move the gasket (33) upward, so that when the gasket (33) moves away from the end surface of the blower fan (2), the tower fan can be operated.

[0024] In this embodiment, the push rib piece (51) includes a push portion (52), and the push portion (52) contacts the contact plate (36).

[0025] In this embodiment, the tower fan having the emergency stop structure further includes a baffle (6) and a limiting plate (8) installed in the rear housing (7), and the baffle (6) and the limiting plate (8) surround to form a mounting space (61) that accommodates the elastic pressure member (4), the push rod (31), the push block (32), and the gasket (33), and the elastic pressure member (4), the push rod (31), the push block (32), and the gasket (33) are located within the mounting space (61). The purpose of designing the baffle is to prevent the push rod (31) and the push block (32) from moving outward and affecting the rotation of the blower fan (2).

[0026] In this embodiment, a limiting hole (81) is drilled in the limiting plate, and when the push rod (31) descends, the gasket (33) mounted on the push rod (31) passes through the limiting hole (81) and comes into contact with the blower fan (2) rotating, thereby limiting the rotation of the blower fan (2). The purpose of designing the limiting hole (81) is to prevent the push rod (31) from shaking in the left and right directions.

[0027] In this embodiment, the elastic pressure member (4) is a spring.

[0028] In this embodiment, the gasket (33) is a rubber gasket. The purpose of selecting a rubber gasket (33) is to increase the contact area between the blower fan (2) and the push rod (31) to increase friction, thereby allowing the rotation of the blower fan (2) to be stopped in an emergency by the friction of the rubber gasket.

[0029] When a user needs to clean the tower fan, if the user removes the back mesh (5) by installing a push rib piece (51) on the back mesh (5), the push rod (31) moves downward by means of a spring built into the push rod (31). When the push rod (31) moves downward, the push block (32) moves horizontally to the right by means of the inclined surface of the side plate (341) that was in contact. Then, as the push block (32) moves horizontally to the right, the push rod (31) moves further downward by the action of the spring, and after the movement, the rubber gasket attached to the push rod (31) also moves downward and comes into contact with the rotating blower fan (2), and the blower fan (2) stops rotating in an emergency due to the frictional force of the rubber gasket. When the separated rear mesh (5) is attached, the rib piece of the rear mesh (5) pushes the push block (32), causing the side plate (341) to move horizontally to the left, and the push rod (31) in contact with the inclined surface of the side plate (341) moves upward. When the push rod (31) moves upward, the rubber gasket moves away from the blower fan (2), allowing the blower fan (2) to rotate.

[0030] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the patent of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention under the concept of the present invention, or any direct or indirect use in other related technical fields, is included within the scope of patent protection of the present invention.
