Description
Technical field
The utility model relates to blower, particularly relates to a kind of single tube blower.
Background technology
Existing garden class blower, installation is blown, the differentiation that arranges of aspiration channel has two kinds usually.A kind of is the blower in the different road of pressure-vaccum, the blower of the type is connected to the blower of host shell, aspiration channel is respectively equipped with independently gas channel, arrange transformational structure to close out dust or inflatable mouth in housing, thus realize the conversion between blow mode and air-breathing mode; Another kind is a kind of single tube blower, and the blower of the type only arranges single gas channel, namely blow, inhale two kinds of mode of operations under what utilize is same gas channel (i.e. same pipe).If U.S. Patent Bulletin number is namely disclose a kind of single tube blower in the patent document of US6735813, this blower is on housing, arrange two air intakes with airflow inlet connection and two air outlets be connected with air stream outlet, and pressure-vaccum pipe is rotationally connected with housing.When the same air intake of pressure-vaccum pipe is docking together, another air intake is closed, one air outlet is closed, another air outlet is communicated with dust bag, is then now air-breathing mode; When the same air outlet of pressure-vaccum pipe is docking together, another air outlet be communicated with dust bag is closed, close for the air intake of same pressure-vaccum pipe connection, another air intake is opened, and is then now blow mode.
Existing a kind of single tube blower has the following disadvantages: owing to carrying out needing to rotate pressure-vaccum pipe when pattern switches, pressure-vaccum pipe can be caused to produce air leakage phenomena with the junction of casing, cause pressure-vaccum effect to decline, because pressure-vaccum pipe is usually comparatively large, therefore carry out effort when pattern switches; In order to when preventing air-breathing mode, human organ (as hand) touches fan blade through pressure-vaccum pipe and produces security incident, must rectilinear pressure-vaccum pipe be made longer and meet security requirement, long pressure-vaccum pipe not only ratio is lacked of proper care, is affected overall appearance, and carries operation inconvenience; When blower blow mode and air-breathing mode, the distance on free end (one end away from housing) the distance ground of pressure-vaccum mouth is that requirement is different, therefore the arm that when blow mode and air-breathing mode, operator carries blower all can not be in the state (having a pattern arm to need to be in case of bending) of freely stretching, and when causing operation, effort comfortableness is poor.
Utility model content
The utility model provides a kind of single tube blower without the need to mobile pressure-vaccum pipe when carrying out pressure-vaccum patten transformation, solves existing a kind of single tube blower and blows suction pipe position and carry out implementation pattern switching by changing and can produce the problem that air leakage phenomena and pressure-vaccum effect decline.
Above technical problem is solved by following technical proposal: a kind of single tube blower, comprise pattern switching mechanism, pressure-vaccum pipe, host shell, be arranged at the motor of host shell, the fan rotated and the switch controlling motor rotation is driven by motor, described host shell is provided with airflow inlet and air stream outlet, described airflow inlet rotates for described fan the air-flow produced and enters described host shell, described air stream outlet rotates for described fan the air-flow produced and flows out described host shell, described pattern switching mechanism comprises the shell linked together with described host shell, the runner being communicated with described airflow inlet and air stream outlet is provided with in described shell, described runner is provided with air intake, inlet and outlet and air outlet, described air intake is provided with air intake switching mechanism, described air outlet is provided with air outlet switching mechanism, described inlet and outlet is provided with and can controls described inlet and outlet at synchronization only with the flow direction control mechanism that described airflow inlet is communicated with the one in both air stream outlets, described pressure-vaccum pipe butts up against described inlet and outlet.When working in blow mode, close air outlet by air outlet switching mechanism, make air intake switching mechanism not close air intake and make flow direction control mechanism cut off inlet and outlet and airflow inlet, after air intake enters, flow to pressure-vaccum pipe from inlet and outlet in the effect downstream of fan and blow out.When working in air-breathing mode, make air outlet switching mechanism not close air outlet, make air intake switching mechanism close air intake and make flow direction control mechanism cut off inlet and outlet and air stream outlet, flow out from air outlet after turnover gas air port enters in the effect downstream of fan thus realize picking up the foreign material such as leaf.
