Description

Technical Field

[0001] The vertical sweeping working appliance is an electromechanical device belonging to the technical fields of temperature control equipment, spraying and coating technology, processing and monitoring technology.

[0002] The products represented by vertical sweeping electrical appliances include: temperature control equipment that mainly uses vertical sweeping to perform work in a vertical state: such as electric fans, radiant electric heaters, blower-type electric heaters; spraying equipment and monitoring equipment, etc. Background Art

[0003] At present, although air conditioners have been basically popularized in households in cities in my country, there are still many middle-aged and elderly people and children who like to play frequently indoors and outdoors. This group of people are accustomed to using economical, energy-saving, and environmentally friendly household appliances that can shake their heads, such as electric fans and electric heaters (collectively referred to as shaking-head appliances), to solve the needs of cooling down in summer and keeping warm in winter.

[0004] However, in the long-term use, people have found that almost all the household appliances that can shake their heads (such as desktop radiant electric heaters, electric heaters commonly known as "little suns" and electric heaters, as well as the large number of shaking electric fans in the world) have the following two defects:

[0005] 1. Most of the existing oscillating head electric appliances can only sweep in the horizontal direction (i.e., sweep left-right, commonly known as "oscillating head"). The direction of their heat radiation work vector line cannot change with the shaking of the head to make two pointing angles up and down, and the irradiation position. This makes the existing floor-standing oscillating head electric heater: if it is placed at a low position, it is difficult to irradiate the user's chest, abdomen and arms; if it is placed at a high position like a table, it cannot irradiate the legs and feet, and cannot warm the legs and feet that are sensitive to cold. - Based on the same reasoning, desktop oscillating head electric fans cannot simultaneously take into account the temperature regulation needs of high and low-positioned targets (parts of the human body, or objects placed at different heights) during the sweeping and blowing process. Because the existing oscillating head working equipment is not designed to provide the target object with up-down reciprocating heating or blowing cooling work, in other words, the existing oscillating head heating appliances and oscillating head blowing appliances "cannot take care of the upper part and the lower part" when working.

[0006] 2. The working mode of all existing shaking head electrical appliances is mostly to blow air or release heat in a reciprocating rotation in the horizontal direction along the vertical axis (usually with a reciprocating rotation range of 90 degrees). The variable power receiving mode brought about by the reciprocating rotation of the working electrical components has its advantages: it enables people to enjoy the effect of "gradually stronger-gradually weaker-interval-gradually stronger-gradually weaker-interval" cycle of blowing air or heat radiation, and enables people to get short intervals of rest, so as not to be blown too cold or too hot due to the continuous action of the energy flow of the set intensity, or to be too hot due to continuous exposure. However, there are drawbacks: Whether it's the airflow from an electric fan or heater or the thermal radiation beam (infrared beam), for objects (such as a person) whose height is much greater than their width, measurements show that the amount of light, heat, or air flow emitted by existing oscillating devices that actually reaches the object during the entire sweeping angle of the head is only one-third of the total energy emitted during the entire rotational sweeping angle range. This wastes two-thirds of the energy and reduces the device's effectiveness. Furthermore, subjectively, people feel that the use of oscillating devices, whether for heating or cooling, is insufficient. Existing oscillating devices cannot fully meet people's needs.

[0007] 3. Although electric fans and rooftop fans capable of sweeping in an "8"-shaped oscillation (or "3D oscillation") have appeared on the market in the past two or three years, they are called "air circulation fans" and are capable of performing a sweeping motion in a figure-eight pattern. However, actual investigations and measurements have shown that the air blowing on a person in this "3D oscillation" motion is even shorter, with the oscillation duration accounting for only one-ninth of the total duration. Therefore, electric fans or heaters that perform a "3D oscillation" motion have lower efficiency. On the other hand, a circulating fan capable of a "3D oscillation" motion must have two oscillation mechanisms: one to drive the horizontal sweeping motion, and the other to drive the vertical sweeping motion. This requires two oscillation motors to drive each. Furthermore, it is rare for such fans to be used solely for vertical sweeping motion.

[0008] Given that existing oscillating devices actually spend more than two-thirds of their rotation cycle performing work on the surrounding environment rather than on a target object (such as the human body), users can feel that during a single sweep, the duration (delay) of the varying strengths of material and energy flows (cold or warm air, or visible or infrared radiation) acting on the target object is insufficient, resulting in low work efficiency and a poor subjective cooling or heating experience for users. This is an area where existing oscillating devices need improvement.

[0009] However, those air conditioner indoor units and air coolers that rely on louvered air guide plates for horizontal or vertical reciprocating air blowing have the disadvantages of large kinetic energy loss and poor energy-saving effect because they use louvered air guide plates to deflect the direction of air flow. Moreover, because the louvered air guide plates block part of the working flow, this design is not suitable for radiant electric heaters, spraying equipment, and monitoring equipment.

[0010] 4. The feet, which are at the end of the human blood circulation, are the key part that causes the human body to feel cold in winter. However, existing irradiation-type heating appliances or hot air-blowing heating appliances do not have a heating working mode with the working direction of "from top to bottom" and "from bottom to top", and a heating working mode with downward directional working to choose from. In real life, this type of equipment is a blank spot, and in order to meet the needs of consumers for quickly warming their feet and legs, this market gap needs to be filled.

[0011] To overcome the four aforementioned shortcomings of existing oscillating-head working appliances, the authors developed a fan and heater with a pitch-and-tilt sweeping motion, known as a vertical sweeping appliance. Experimental testing using a prototype device demonstrated that when the appliance's head performs work in a pitch-and-tilt sweeping motion (i.e., its work vector center continuously pitches and tilts along a vertical line to work on a person or object), the work vector of the vertical sweeping appliance head never leaves the surface of the object being worked on, moving up and down. During a single pitch-and-tilt sweeping stroke, the head can continuously and uninterruptedly apply a "gradually increasing-decreasing-gradually increasing-decreasing" action to an object in an upright position (i.e., one whose vertical dimension is greater than its horizontal dimension, such as a human body or a tall object like a wet sheet hanging from a height) to the work. These actions can be broadly applied to include blowing, radiating, spraying, monitoring, and other meaningful actions. Experimental observations indicate that when the handpiece performs work in a pitch-and-sweep motion, the work performed on the receiving object lasts for the entire cycle, remaining within the directional range of the airflow or radiant heat flow (only the slope of the receiving angle changes periodically), with no interruption in the energy flow. Furthermore, because the directional angle constantly changes, the work flow rate (generated by the vertically sweeping handpiece during a single sweep) experienced significant variations in intensity, thus enhancing user comfort. This is a significant advantage of appliances using a pitch-and-sweep motion.

[0012] In summary, to address the technical deficiencies of current oscillating-head electrical appliances, the present invention proposes a novel solution: an electromechanical device that operates in a reciprocating pitch-and-tilt sweeping motion (during its sweeping motion) without relying on a deflectable air deflector. Some of these devices are capable of operating in either a pitch-and-tilt sweeping or a horizontal sweeping motion, i.e., they are electromechanical devices capable of variable-axis sweeping motion. These electromechanical devices are collectively referred to as "vertical sweeping devices." Summary of the Invention

[0013] Vertical sweeping electrical appliances belong to the fields of temperature control equipment, spraying and coating, and monitoring technology. Products embodying vertical sweeping electrical appliances include temperature control equipment that primarily performs vertical sweeping motions, such as electric fans, radiant heaters, and blower heaters; spraying and coating equipment; and monitoring equipment.

[0014] The vertical sweeping working appliance is based on the design of "machine head-machine head movable holding frame, supporting body and shaking head mechanism". The vertical sweeping working appliance is equipped with a separate set of shaking head mechanism.

[0015] The machine head-machine head movable holding frame complex and the shaking head mechanism together constitute the dynamic working component of the vertical sweeping working appliance.

[0016] Vertical sweeping power generators are green, energy-saving power generators with a reciprocating reversing mechanism for the power vector lines of their own motor heads (commonly known as a "swinging mechanism"). They are unique in that they utilize vertical reciprocating sweeping motions (i.e., "up-down sweeping," or "pitch-and-roll sweeping") as their sweeping characteristic. Some vertical sweeping power generators can switch their sweeping mode to horizontal reciprocating sweeping without adding a swinging motor or swinging mechanism, easily achieving horizontal sweeping.

[0017] From the working mode, vertical sweeping working appliance is a type of electromechanical device whose head can perform up-down reciprocating sweeping (or pitch-and-fall sweeping) mainly in the vertical direction. This working mode can perform work on the target object in a continuous manner with strong-weak periodic changes.

[0018] The vertical sweeping working appliance has a specially designed head, a head movable holding frame, a supporting body and a separate set of shaking head mechanism.

[0019] A vertical sweeping actuator has a horizontally arranged sweeping shaft. Its normal operating position is with its movable frame upright and the sweeping shaft horizontal, allowing it to perform vertical reciprocating sweeping motions. A portion of the vertical sweeping actuator can be converted to a horizontal reciprocating rotational motion by changing the mounting or fixed position and angle of its movable frame. This conversion allows this portion of the actuator to function as a horizontal sweeping actuator.

[0020] The handpiece is the characteristic working unit of a vertically sweeping electrical appliance. Common applications for handpieces include electric fans and electric heaters. These heaters include radiant heaters (commonly known as "little sun" heaters) and blower heaters (such as PTC heaters and metal heating wire heaters).

[0021] The "vertical sweep" of the handpiece refers to the motion in which the handpiece's power vector line periodically and vertically changes direction in a pitch-and-elevation (or "up-and-down") pattern during the power generation process. Vertical sweeping is also known as pitch-and-elevation sweeping.

[0022] The "horizontal sweeping" of the machine head refers to the movement in which the working vector line of the machine head can make periodic reciprocating left-right direction changes in the horizontal direction during its working process, which can also be called left-right sweeping; in the manufacturing industry and people's lives, the reciprocating sweeping action of the machine head is commonly known as the "shaking head" action, and the corresponding driving mechanism is called the "shaking head mechanism".

[0023] For radiant electric heaters, since the vertical pitch-and-tilt sweeping motion of the heater head will radiate light upward, to protect the user's eye health, the heating element in the heater head of vertically sweeping radiant electric heaters, except for some consumers who have special needs, all use heating tubes or heating rods that emit almost no visible light and only infrared rays. (For example, one method is to use a steel heating tube coated with a refractory clay-graphite powder-cement mixture and containing a resistance wire filled with magnesium oxide powder as the core, which is simply referred to as a metal heating tube; another method is to use a spiral carbon fiber tow or metal resistance wire encapsulated in a glass tube coated with a visible light-blocking coating, which is simply referred to as a glass shell heating tube).

[0024] From a structural perspective, a vertical sweeping actuator is an electromechanical device (referred to as a "unit") that enables the handpiece to sweep back and forth. In addition to the handpiece, the unit comprises a support, a handpiece movable retaining frame, a handpiece sweeping shaft, and a sweeping drive mechanism (commonly known as an oscillating mechanism). Its most essential features are the handpiece, the handpiece movable retaining frame (the two together form the handpiece-handpiece movable retaining frame complex), a horizontally arranged handpiece sweeping shaft, and a separate vertical oscillating mechanism.

[0025] The machine head movable retaining frame is a frame-like body surrounded by curved or straight edges, and the frame-like body is closed or has an open opening. On it are the movable mounting positions or mounting structures of the machine head (such as shaft holes, bearings, flange seats, etc.), as well as the mounting positions or mounting structures of the entire rocking mechanism or rocking mechanism components (such as the support shaft and screw holes of the rocker arm, etc.). Common machine head movable retaining frames are circular, oval, or rectangular frame-like bodies.

[0026] The support body is the supporting component of a vertical sweeping power unit. It supports the power unit, including the head and the head's movable retaining frame, maintaining their stable working posture and positioning. Commonly used support bodies can be embodied as columns, bases (chassis), and composite brackets. Some vertical sweeping power units incorporate the support body and head's movable retaining frame as a single unit (e.g., as in Example 1).

[0027] The support body is a carrier of the machine head and control circuits and is part of the unit. It plays various roles in bearing the weight of the machine head and maintaining its position and working posture. The types of support bodies include: (1) independent pillars (collectively referred to as "pillars") and bases (also called "chassis"); (2) multi-pillar support groups (whose structure has a chassis but no diagonal ribs); (3) composite supports (whose structure includes pillars, crossbeams, bottom frames, ground beams, diagonal ribs, control panels, etc.); (4) some types of vertical sweeping units have a structure in which the support body and the machine head movable holding frame are integrated (i.e., the support body and the machine head movable holding frame are manufactured as one piece).

[0028] The vertical sweeping working appliance is equipped with a separate set of shaking head mechanisms, which ensures that the unit can choose to use the reciprocating pitch-and-tilt periodic cyclic action of the machine head itself to perform work on the working object in a continuous, strong-weak periodic changing manner.

[0029] The installation position of the oscillating mechanism of the vertical scanning working appliance is selected according to needs: on the machine head, or on the machine head movable holding frame.

[0030] The shaking mechanism belongs to the known technology. The categories of the shaking mechanism of the known technology adopted by the present invention include the following three types:

[0031] The first type of shaking head mechanism: a shaking head mechanism composed of the impeller coaxial reduction gearbox and the rocker claw-rocker arm-column shaft at the head and tail of the electric fan; this shaking head mechanism is referred to as the "impeller coaxial reduction gearbox shaking head mechanism" in this article.

[0032] The second type of shaking head mechanism: a shaking head mechanism composed of an independently installed claw-pole synchronous reduction motor-claw rocker arm shaking head mechanism installed in the head of some shaking head electric fans and the head of shaking head electric heaters; this shaking head mechanism is referred to as "independent shaking head mechanism (with rocker arm)" in this article.

[0033] The third type of oscillating mechanism is installed between the head and column of some oscillating fans or between the head and column of some oscillating heaters. It is driven by a separately mounted, reversible claw-pole synchronous reduction motor and connected by a reciprocating boss, short tube, or flange. This oscillating mechanism consists of a reversible claw-pole synchronous reduction motor (also known as a "non-directional motor" in the industry, designated CCW), a limit block or limit slot, and an output shaft (or rotary sleeve). This oscillating mechanism is also a separate oscillating mechanism. This article will refer to it as the "reversible oscillating motor-rotating sleeve oscillating mechanism."

[0034] As far as the application in household appliances is concerned, the electric fans in vertical sweeping work appliances can adopt the first to third types of shaking head mechanisms; while the head of the electric heater lacks the main motor shaft for installing the axial flow electric fan impeller, so the electric heater can only use the second to third types of shaking head mechanisms mentioned above.

[0035] As previously mentioned, the normal operating state of a vertical sweeping actuator is in an upright position, with the handpiece's movable frame in an upright position and the handpiece's sweep axis in a horizontal position. In this position, when the handpiece sweeps, it sweeps back and forth in an up-and-down direction, i.e., performing a pitch-and-roll sweep (also known as "vertical sweep" or "up-and-down sweep").

[0036] A part of the vertical sweeping working electrical appliance can be transformed into an electromechanical device that reciprocates and rotates in the horizontal direction by changing the installation or fixed position and angle of its head movable holding frame so that the head sweeping axis becomes vertical.

[0037] For example, the head of a type of vertical sweeping work appliance can perform reciprocating sweeping work in the vertical direction with the cooperation of the shaking mechanism, that is, pitch-and-tilt sweeping work; they can also be placed or fixed by changing their installation position from vertical to horizontal (that is, changing to a "side-up" manner) to perform reciprocating sweeping work in the horizontal direction, that is, horizontal sweeping work (such as the mechanism design and working state described in Examples 1 and 2, see Figure 1 、 Figure 2)。The principle is as follows: When needed by the user, with the help of a specially designed part carried by the unit itself, where the head of the unit is movably connected to the head activity retaining frame held thereon, the head activity retaining frame of the vertical sweeping working electrical appliance or the entire body can be laterally laid down on the vertical plane. The head sweeping shaft changes from the horizontal position to the vertical position and obtains stability by means of the gravity of the unit itself, or is fixed by means of a locking nut or bolt or pressing block; thus, the head of the unit can perform reciprocating sweeping working actions in the horizontal direction. (At this time, the sweeping working mode of the unit changes from vertical sweeping working to horizontal sweeping working.)

[0038] In specific product applications, according to the content of the work, the forms of vertical sweeping working electrical appliances include: vertical sweeping electric fans, vertical sweeping radiant heaters, vertical sweeping blowing heaters (i.e., vertical sweeping warm air blowers), vertical sweeping spraying machines, vertical sweeping illuminators, vertical sweeping monitors, and other devices.

[0039] In this article, Embodiment 1 gives a solution that can convert from vertical sweeping working to horizontal sweeping working by changing the placement (positioning) angle of the head activity retaining frame; Embodiment 2 gives a solution that realizes the conversion from vertical sweeping working to horizontal sweeping working by changing the installation angle of the head activity retaining frame; Embodiment 3 shows that for the same vertical sweeping working electrical appliance, by replacing the head, the conversion of different seasonal uses between the vertical sweeping electric heater and the vertical sweeping electric fan of the unit can be achieved.

[0040] All the units and attached drawing legends involved in the embodiments in this article can be easily made into real products in the forms of electric fans and electric heaters.

[0041] Next, in combination with the accompanying drawings of the specification and taking the embodiments as specific design examples, the solutions and their specific technical details of the "vertical sweeping working electrical appliance" are given.

[0042] In the design of the present utility model, there is a single-head desktop vertical sweeping working electric fan (abbreviated as "desktop vertical sweeping electric fan"), as Figure 1 shown.

[0043] Figure 1 In the small figure a of [reference], the front view of this unit shows a structure in the shape of a "hui" character, which is composed of a head activity retaining frame 17, an electric fan head 3, and a frame (including a left column 1, a right column 2, a top cross beam, a load-bearing bottom strip, a ground beam, and reinforcing ribs); from the side view, it can be seen that the left and right columns, the load-bearing bottom strip, and the head activity retaining frame 17 form an "I" - shaped structure. A vertical shaking head mechanism is arranged between the head activity retaining frame 17 and the electric fan head 3. Figure 1 shows the working state where the electric fan is placed upright and the head makes a up - down pitching - yawing sweep (vertical sweep).

[0044] The supporting body and the movable holding frame of the machine head of this machine unit are manufactured as one piece.

[0045] The machine head's movable retaining frame 17 consists of two upright columns (referred to as the "left column" and "right column"), each with a rectangular cross-section. Atop the left and right columns 1 and 2 are rigidly connected by a top crossbeam, which also serves as a handheld device for easy movement while the machine is in an upright position. At the bottom of these vertical components are two longitudinal bottom rails (the left and right load-bearing bottom rails 5 and 6), rigidly connected and extending forward and backward. There are also transverse ground beams (one each fore and aft) that are vertically and firmly connected to the left and right load-bearing bottom rails 5 and 6. Triangular diagonal ribs are installed at the points where the left and right load-bearing bottom rails 5 and 6 connect to the left and right columns 1 and 2, reinforcing the overall rigidity of the machine head's movable retaining frame 17. The frame is integrally injection-molded from white polyvinyl chloride; the movable retaining frame 17 is a hollow structure.

[0046] One end of the head sweeping shaft 18 of each section extending from both sides of the head of this vertical sweeping electric fan is respectively inserted into the bearing holes at the same height position of the left column 1 and the right column 2 of the head movable holding frame 17.

[0047] The oscillating mechanism of Example 1 utilizes an independent oscillating motor driven by a pawl-type rocker arm. This is the second type of oscillating mechanism described above, namely, the "independent oscillating mechanism (with rocker arm)." The specific structure is as follows: a claw-pole permanent magnet synchronous oscillating motor with a reduction gear set is fixedly mounted on the handpiece on the left side facing the user, a certain distance behind the handpiece sweeping axis. The pawl connected to its output shaft is flexibly mounted on a hole at one end of the rocker arm. The hole at the other end of the rocker arm flexibly mounts on a short shaft column protruding from the left upright 2 of the movable retaining frame and approximately 20 mm below the centerline of the handpiece sweeping axis 18.

[0048] When the product is made, the oscillating mechanism on the machine head is often covered in a machine head shell for a neat, smooth and beautiful appearance, just like an ordinary oscillating electric fan; the machine head shell of the vertical sweeping work appliance also plays a role in shielding and shaping.

[0049] The keys, buttons, working state selection knob and power indicator light for unit circuit control are arranged on the control panel 19 near the lower part of the right column 2.

[0050] Figure 1 Small figure b shows the vertical sweeping electric fan placed on its side with the head performing reciprocating horizontal sweeping motion in the left-right direction.

[0051] When this single-head vertical sweeping electric fan is used in a clockwise and horizontal direction, the left column 1 is located at the upper part of the unit, and the left column 1 becomes the "upper beam" of the unit.

[0052] Because the unit's support body and head movable retaining frame are manufactured as one piece, this design utilizes a single main working head, a single oscillating motor, and a single oscillating mechanism dedicated to oscillating motion. By simply changing the placement angle of the head-head movable retaining frame complex, the unit can freely switch between two sweeping motion modes: an up-down sweeping motion in an upright position and a left-right horizontal sweeping motion in a sideways position. This unique design offers a simple, free, and efficient variety of working functions unavailable in any existing oscillating electric fan (including those capable of "3D oscillating motion").

[0053] Some single-head vertical sweeping work appliances are designed with independent supports and a large-diameter circular fixed chassis.

[0054] Figure 2 The present invention shows a floor-standing vertical sweeping electric fan with independent support 12 and circular fixed base 13. (See Example 2.)

[0055] Figure 2 The small diagram c in the figure shows that the head sweeping axis 18 is arranged horizontally, and the electric fan head 3 can only perform pitch-and-tilt sweeping in the up and down directions.

[0056] Depend on Figure 2 As can be seen from the small picture c, the floor-standing vertical sweeping electric fan is in an upright state. The upper part of the unit is a set of head-head movable retaining frame complex, which is composed of a head movable retaining frame 17, a vertical shaking mechanism and a fan head 3.

[0057] The vertical sweeping electric machine's head movable retaining frame 17 is provided with two locations 90° apart on the vertical plane (frame plane) to securely engage the top end of the independent support 12 below it. This head connector 14 is used to securely engage the axial-flow fan head 3 onto the top end of the independent support 12. A fastening screw is provided near the edge of the head connector 14 to secure the axial-flow fan head 3.

[0058] Figure 2 Panel d shows the vertical sweep fan head 3, along with its movable retaining frame 17, rotated 90° clockwise along the vertical plane and inserted into the top of the independent support 12 in a sideways position. Now, the fan head's sweep axis 18 is vertically positioned, and the fan head 3's sweeping motion is changed to a horizontal sweeping motion only in the left-right direction. This unit is an example of a specially designed vertical sweeping electric appliance capable of both vertical sweeping and horizontal sweeping motion by changing its mounting position.

[0059] Since the sweeping direction of the vertical sweeping electric appliance is up-down sweeping (pitch-up sweeping), this sweeping mode is significantly different from most existing oscillating electric appliances. Therefore, the use of vertical sweeping electric appliances can produce the following beneficial effects:

[0060] 1. In the upright working state, the vertical sweeping working appliances used in the two specific products of oscillating electric fans and oscillating electric heaters will experience the following unique phenomena during their working process:

[0061] (1) When the vertical sweeping electric fan is placed on the table in an upright position and sweeps to perform work, its head sweeping axis is in a horizontal position on the movable holding frame. Driven by the oscillating mechanism, the head impeller blows air from the top to the bottom and then from the bottom to the top in a reciprocating cycle. During the reciprocating swing of the head blowing center line from top to bottom and then from bottom to top, compared with the traditional left-right oscillating electric fan, the work center line of the vertical sweeping electric fan can always stay within the target object (such as a human body that needs to be cooled, or hot food on the dining table, etc.), forming a continuous blowing work on the target object from weak to strong and then from strong to weak.

[0062] When using a vertical sweeping fan, the body is subjected to a cyclical, upward-downward and downward-backward flow, with a continuously fluctuating flow. This sweeping process eliminates the interruptions in air flow experienced by the target (as with traditional left-to-right oscillating fans), resulting in significantly greater airflow. This method of operation is over 60% more efficient than the traditional left-to-right sweeping method, equivalent to 1.6 times that of conventional left-to-right oscillating fans. Therefore, vertical sweeping fans offer greater cooling efficiency, faster cooling, and a greater sense of coolness. Overall, the user's experience is significantly better than the continuous, harsh airflow of non-oscillating, directional fans.

[0063] (2) When the vertically sweeping electric heating radiator (or radiant electric heater, commonly known as "little sun") sweeps in an upright state to do work, the center line of the electric heating radiation of the head never leaves the target object (such as the human body or wet clothes hanging to be dried), and heats the body from the feet to the chest and to the head and face in a gradual, even and reciprocating manner. Since the heating sensation never disappears, people feel that they are being heated continuously and comprehensively. Since the heat generated by the head does not have a 2 / 3 blank period of sweeping directed to the surrounding space in each shaking stroke, the heating efficiency is high; however, the target object (such as the human body) is not subjected to a static and strong heat that is always concentrated, thereby increasing the comfort of heating and avoiding the burns to the human body and other targets that may be caused by the long-term directional irradiation of the head's photothermal components.

[0064] 2. Vertical sweeping work appliance can work in an upright state (the sweeping axis of the machine head is in a horizontal position), that is, the machine head performs work while performing continuous up and down reciprocating sweeping; it can also work in a horizontal state (the sweeping axis of the machine head is in a vertical position), at which time the machine head performs continuous left and right reciprocating sweeping to perform work.

[0065] In other words, a part of the vertical sweeping working electrical appliance, with the help of the change of vertical direction brought about by the installation or placement of the machine head-movable retaining frame complex of the machine unit, can achieve switching between vertical and horizontal directions and perform reciprocating sweeping to perform work with only a set of machine heads and an shaking head mechanism.

[0066] Compared to commercially available air circulation (electric) fans capable of "3D oscillating" (or "figure-8"-shaped) sweeping motion, the unique advantage of a single-head vertical sweeping power supply is that it eliminates the need for two oscillating motors and two oscillating mechanisms for horizontal and vertical sweeping respectively. A single-head vertical sweeping power supply has only one oscillating motor and one oscillating mechanism. Simply adjusting the orientation of the head's movable retaining frame by 90° allows the switch between pitch and horizontal sweeping modes.

[0067] 4. On the other hand, compared with the air conditioner indoor unit and the water curtain air cooler, the vertical sweeping power appliance is an electrical device that relies on the pitch-and-tilt sweeping of the machine head rather than the pitch-and-tilt sweeping of the air guide plate to perform work. At the port where its power vector (such as airflow) is output, there is no air guide plate group installed on the air outlet of the air conditioner indoor unit or the air outlet of the water curtain air cooler. The unit eliminates the obstruction of the air guide plate group with changing deflection angle during its work process (they will consume part of the kinetic energy and heat energy carried by the air flow), so the power coefficient of the vertical sweeping power appliance is relatively high. From this respect, the vertical sweeping power appliance is more energy-efficient.

[0068] 5. Compared with traditional high-power air conditioners (which include heaters or radiators that collect air energy and geothermal energy) and heating equipment composed of boilers, water pipes, radiator racks or floor heating coils, vertical sweeping power appliances have the advantages of simple structure, low purchase cost, greatly reduced energy consumption, economical electricity saving, reliable operation, energy saving and environmental protection. They are more suitable for use in the vast southern regions where the average winter temperature is above 5 degrees Celsius. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Figure 1 It is a desktop vertical sweeping power electric fan diagram.

[0070] Figure 1 The small figure a in the figure shows that this is a vertically sweeping electric fan with a flat overall shape, a "U" shape when viewed from the front, and an "I" shaped head movable retaining frame and a vertical shaking mechanism when viewed from the side. Figure 1 The small diagram a in the figure shows that the electric fan is placed upright and the head is performing pitch-and-tilt sweeping (vertical sweeping) in the up and down directions.

[0071] Figure 1 The small diagram b shows the vertical sweeping electric fan lying on its side with the head making reciprocating horizontal sweeping movements in the left-right direction.

[0072] Figure 2 It is a floor-standing vertical sweeping electric fan.

[0073] This is a floor-standing electric fan unit with a circular fixed chassis, independent support, single fan head, and a vertical oscillating mechanism. It can achieve both vertical and horizontal sweeping air supply with just one oscillating mechanism.

[0074] Figure 2 The small figure c shows that the movable holding frame 17 of the head is inserted in the upright position (normal position) and fixed on the top of the independent pillar 12, and the head sweeping shaft 18 is arranged in the horizontal position and can only perform vertical sweeping in the up-down direction to supply air.

[0075] Figure 2 Panel d shows the fan head 3 of the unit, along with the head movable retaining frame 17, rotated 90° to the left (tilted) along the vertical plane and inserted into the top of the independent support 12 in a sideways position. After this posture change, the head sweeping axis 18 changes from a horizontal to a vertical position, and the direction of its reciprocating rotational motion changes from a vertical sweeping motion capable of only up-down air supply to a horizontal sweeping motion capable of only left-right air supply.

[0088] [Example 1] A vertical sweeping desktop fan

[0089] like Figure 1 As shown in panel a of the figure, this is a desktop electric fan with a unique head movable retaining frame of the present utility model. This vertical sweeping electric fan has an "I"-shaped head movable retaining frame 17 (i.e., the frame) and a set of oscillating mechanisms. The support body and head movable retaining frame of the unit are manufactured as a whole.

[0090] This vertical sweeping electric fan is flat, shaped like a "U" (U) from the front, and has an "I" (I)-shaped head movable retaining frame 17 and a vertical swing mechanism from the side. Panel a in the figure shows the fan in an upright position, with the fan head 3 performing a vertical sweeping motion (pitch-and-tilt).

[0091] The "I"-shaped head movable retaining frame 17 (i.e., the frame) of the unit is composed of rectangular columns standing on either side as upright components (referred to as "left column 1" and "right column 2" respectively). At the top of the left column 1 and right column 2 is a top crossbeam that rigidly connects them. At the bottom of the upright components are two longitudinal bottom strips (a load-bearing left bottom strip 5 and a load-bearing right bottom strip 6) that are rigidly connected and extend forward and backward, one on each side. There are also transverse reinforcing ribs 7 (one front and one rear) that are perpendicular to the load-bearing left bottom strip 5 and the vertical right bottom strip 6. The reinforcing ribs 7 located in the front are flattened on the upper and lower sides. Triangular diagonal ribs (diagonal braces) are also provided at the load-bearing left bottom strip and at the connection points with the left column 1, the load-bearing right bottom strip 2, and the right column 2 to enhance the overall rigidity of the movable retaining frame. To ensure the overall rigidity of the movable retaining frame, the movable retaining frame of this example is a hollow structure, integrally injection-molded from modified polystyrene.

[0092] On both sides of the head of this vertical sweeping electric fan, there is a symmetrically exposed end of the head sweeping shaft 18 (i.e., the rotating shaft that determines the pitch movement of the head), which is respectively inserted into the bearing holes at the same height position of the right column 2 and the right column 1 of the head movable holding frame 17. The shaking mechanism adopts the second type mentioned above, namely, the "independent shaking mechanism (with rocker arm)". The setting and structure of the shaking mechanism are as follows: on the right side facing the user, a certain distance behind the head sweeping shaft, a claw-pole permanent magnet synchronous shaking motor with a reduction gear set is fixedly set - the shaking claw connected to its output shaft is movably sleeved on one end hole of the rocker arm; the hole on the other end of the rocker arm is movably sleeved on a short shaft column protruding from the right column of the movable holding frame and about 20 mm below the center line of the head sweeping shaft.

[0093] The shaking cycle of the shaking mechanism is generally selected between 2.5 and 5 revolutions per minute in accordance with the comfort requirements of use.

[0094] The unit's circuit control keys, buttons, working status selection knob and power indicator light are set in the middle of the right column.

[0095] Figure 1 The b-panel shows that the electric fan is placed horizontally to the right as a whole (in a side-lying position) and the head is performing a reciprocating horizontal sweeping motion in the left-right direction.

[0096] When this vertical sweeping electric fan is used horizontally, the state is that the original right column 2 of its head movable holding frame 17 (i.e., frame) is located at the bottom of the unit and becomes part of the base, and the left column 1 becomes the "upper beam" of the unit.

[0097] The supporting body and the movable holding frame of the machine head are manufactured as one piece.

[0098] This unit utilizes a single head, a single oscillating motor, and a dedicated oscillating mechanism. Simply by changing the angle of placement, it can freely switch between two sweeping modes: an up-and-down sweeping mode in the upright position and a left-and-right horizontal sweeping mode in the sideways position. This design feature enables a simple, compact structure and rapid, free-switchable operation, a capability unmatched by any existing oscillating appliance (including fans capable of "3D oscillating" motion).

[0099] [Example 2] Floor-standing oscillating electric fan with switchable vertical and horizontal positions

[0100] like Figure 2 As shown, it is a floor-standing electric fan unit.

[0101] This unit is an oscillating fan that can allow the user to change the installation angle of the head-head movable retaining frame complex on the top of its independent support, and choose to switch between the pitch-sweep working mode or the left-right sweeping working mode.

[0102] The core component of this embodiment is a head-head movable holding frame complex consisting of an electric fan head 3 and a set of annular head movable holding frame 17 (with an oscillating mechanism).

[0103] Figure 2 The small diagram C in the figure shows a floor-standing electric fan that performs vertical sweeping motion. Figure 2 As can be seen from the small figure c, the floor-standing vertical sweeping electric fan with independent pillars 12 and a circular fixed chassis 13 is in an upright state. The upper part of the unit is an electric fan head 3 with a movable head retaining frame 17 and a vertical shaking mechanism; because its head sweeping shaft 18 is fixed in a horizontal state, the electric fan head can only perform reciprocating up-down (pitch-elevation) sweeping motions in the vertical direction to perform work.

[0104] The oscillating mechanism of this floor-standing oscillating electric fan with convertible vertical and horizontal postures adopts the third oscillating mechanism mentioned above, namely the "reversible oscillating motor-rotating shaft sleeve oscillating mechanism", to achieve the repetitive sweeping work of the machine head.

[0105] Two head connectors 14 are located 90° apart on the vertical edge of the movable head retaining frame 17 of this vertical sweeping power unit. These are designed to fit over and secure the top of the independent support 12 below. These connectors 14 are used to insert the axial-flow fan head 3 onto the top of the independent support 12. Locking screws are located near the edges of these connectors 14 to secure the head and movable head retaining frame complex.

[0106] The various circuit control switches and knobs of the unit are installed at the rear of the machine head (not visible in the figure).

[0107] Figure 2 Panel d shows the unit converted to a horizontal sweeping floor-standing electric fan: Upon user selection, the vertically sweeping fan head 3, along with its movable head retaining frame 17, has been rotated 90° clockwise along the vertical plane. The previously horizontal sweeping shaft 18 is now vertically positioned, and the head-movable head retaining frame complex is now positioned sideways and nested atop the independent support 12. By virtue of the change in the mounting angle of the movable head retaining frame 17, the unit's fan head 3 now operates in a reciprocating left-right sweeping motion exclusively in the horizontal direction.

[0108] [Example 3] A vertical sweeping electrical unit capable of quickly switching between an electric fan head and an electric heater head

[0109] like Figure 3 The small figure f in the figure shows the unit with the radiant heater head installed (rotated upward to a position close to the limit); the small figure g shows the electric fan head waiting to be installed on the composite frame of the unit.

[0110] This thermostat utilizes a single composite frame. Simply by replacing the power head in summer and winter, it can function as both an electric fan in summer and a radiant heater in winter. This unit's power is limited to vertical pitch-and-sweep motions.

[0111] This unit's composite frame features a U-shaped (front-facing) fixed chassis constructed from a combination of steel pipe and engineering plastics. Its upright components are the left and right columns 1 and 2, located on the left and right sides of the machine head. Crossbars at the tops of these columns also serve as handles for the unit. The inclined left and right columns 1 and 2 stand atop the U-shaped chassis and are secured by diagonal braces.

[0112] On the inner wall of the right column 2, the aforementioned third type of shaking mechanism, namely the "reversible shaking motor-rotating shaft sleeve shaking mechanism" is set. That is, its shaking mechanism is installed in a flange seat, and the exposed end of the rotating shaft sleeve is inserted into the head connector sleeve 14 (short ear shaft) on the right side of the power fan head 3 or the radiant electric heater head 15-head movable retaining frame 17 (with the help of tenon), thereby transmitting the torque of the up-and-down reciprocating shaking and sweeping movement to the head movable retaining frame 17-head complex. On the inner surface of the left column 1 at the same height (the side facing the head movable retaining frame), there is a left shaft hole for the head sweeping shaft 18 on the head movable retaining frame 17 to form a horizontal movable support.

[0113] The heating element of the radiant heater head 15 of this unit is a metal heating tube 21, which is controlled to output two power levels of 500W and 1000W respectively. The power of the fan head 3 is 65W.

[0114] The fan head's movable frame 17 and other moving parts are made of ABS engineering plastic. Other components are injection-molded from polypropylene or polyvinyl chloride. Behind the fan head 3 and in front of the right column 2 are a power range knob, a head movement control knob, and a remote control signal receiving window, respectively, for manually or remotely selecting the fan's power mode, power level, duration of each power cycle, and other parameters.

[0115] The total height of the entire unit is 85 cm, which is suitable for placement next to the dining table, sofa, etc. Whether using electric energy to "heat" for heating in winter or blowing air to cool down in summer, it can produce "from weak to strong, and then from strong to weak, continuously from the legs and feet to the head and chest", which is both comfortable and efficient.
