Abstract

The utility model discloses a safe-type shower which comprises a water tank, a heater, a hearer control circuit, a water pump, a water pump control circuit and a shower head assembly. The water pump is arranged between the water tank and the shower head assembly. The safe-type shower is characterized in that an energizing change-over switch is arranged between the heater control circuit and the water pump control circuit to enable only one of the heater and the water pump to work after being energized. According to the safe-type shower, the water pump control circuit and the heater control circuit are independently arranged, the energizing change-over switch automatically controls that only one of the two circuits works after being energized, and therefore safety accidents caused by simultaneous work of the heater and the water pump can be avoided. In addition, the aims of the safe-type shower can be achieved by the situation that only the energizing change-over switch is additionally arranged, and the safe-type shower is simple and reasonable in structure.

Description

The safety-type shower

Technical field

The utility model relates to the shower technical field, is especially a kind of shower that can obviously improve safety in utilization.

Background technology

Chinese utility model patent number: ZL201220149408.1, disclose name and be called " a kind of portable shower ", its Granted publication day: on October 31st, 2012; This shower, comprise water tank, heater, water pump, elastic force power line winding box, attaching plug and gondola water faucet etc.; This shower,, due to small volume, lighter weight, facilitated people's use to a certain extent; Yet this shower still has the following disadvantages: (1), in view of safe change-over switch is set between water pump and heater, therefore, during user's shower, often exists heater and water pump to work simultaneously, has potential safety hazard; (2) water pump control circuit still provides power supply by alternating current (forceful electric power), and is both dangerous, during again easily because of shower, there is no power supply, causes the user to use.

The utility model content

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, and heater and water pump can only singlely work alone, and greatly improve the shower of product safety in utilization.

The purpose of this utility model is to realize like this.

The safety-type shower, comprise water tank, heater, control circuit for heater, water pump, water pump control circuit and shower components, water pump is arranged between water tank and shower components, it is characterized in that, be provided with the energising change-over switch between described control circuit for heater and water pump control circuit, so that can only single energising work between heater and water pump; This kind of shower, by minute being arranged water pump control circuit and control circuit for heater, and automatically control two circuit by the energising change-over switch can only single energising work, do like this, can avoid heating and water pump to work simultaneously, cause security incident; And such shower, only, by setting up the energising change-over switch, can realize this patent purpose, and it is simple and reasonable for structure.

The purpose of this utility model can also be by the following technical solutions.

As preferred scheme, described water pump control circuit includes battery, and the battery output voltage is less than 36V, and battery and water pump electric connection; By independently power supply is set at shower, to offer pump working; Do like this, the user when using shower, need not to worry external power source situation (as: external power source power failure); And the battery output voltage, less than 36V, belongs to safe voltage, and the user when using shower, need not citing security concerns.

As scheme more specifically, described control circuit for heater comprises external power supply line socket and the circumscripted power line plug that mutual grafting coordinates, external power supply line socket and heater electric connection; That is to say, heater coordinates by plug and socket, with external communication, is electrically connected to.

As preferred scheme, described energising change-over switch comprises alternating current switch, direct current switch and conversion control circuit, alternating current switch and direct current switch are connected on respectively on control circuit for heater and water pump control circuit, conversion control circuit is according to the external power source input signal, judge and cut off the direct current switch when controlling the alternating current switch connection, or the alternating current switch is connected the direct current switch when cutting off; Therefore,, when the external power source input, can be differentiated by conversion control circuit, connect alternating current switch or the work of water pump gauge tap, avoid both to work simultaneously, cause security incident.

As another priority scheme, described energising change-over switch comprises alternating current switch and the direct current switch of mutual interlock, alternating current switch and direct current switch are connected on respectively on control circuit for heater and water pump control circuit, and when alternating current switch and direct current switch are static, one often is in and opens, and another is in normally closed; That is: alternating current switch and direct current switch, when arbitrary switch motion is closed, must drives another switch motion and disconnect, and to guarantee two switches, a switch energising job only arranged.

Certainly, can be also such an embodiment: described energising change-over switch be a direct current touch-switch, the direct current touch-switch is normally closed type, it is connected on described water pump control circuit, the direct current touch-switch is arranged on by the external power supply line socket, when the circumscripted power line plug inserted the external power supply line socket, the direct current touch-switch was pressed on the plug top; When the user needs the shower heating, the circumscripted power line plug can be inserted the external power supply line socket, here, plug can push up presses the direct current touch-switch, thereby cuts off water pump control circuit; When transfering to power-line plug, the connection that resets of direct current touch-switch, at this moment, the user directly presses pump switch, can connect pumping for water pump work, and the user can shower.

As more perfect scheme, it also comprises a pump switch, and pump switch is connected in series with direct current touch-switch, water pump control circuit; Therefore,, even power-line plug is transferred to, also need the user to start pump switch, water pump could be worked.

The bottom of described water tank has osculum, and the osculum place is provided with filter screen, and osculum connects the pumping for water pump end; And also be provided with anti-electric wall between the filter screen in tank drains hole and pumping for water pump end; Like this, both can filter water, and prevent from again causing security incident because of electric leakage to the user.

The beneficial effects of the utility model are as follows.

(1) this kind of shower, by minute being arranged water pump control circuit and control circuit for heater, and automatically control two circuit by the energising change-over switch can only single energising work, do like this, can avoid heating and water pump to work simultaneously, cause security incident; And such shower, only, by setting up the energising change-over switch, can realize this patent purpose, and it is simple and reasonable for structure;

(2) have, in view of the water pump use self-contained storage battery of shower, the user need not to worry external power source situation (as: external power source power failure) again; And the battery output voltage, less than 36V, belongs to safe voltage, and the user when using shower, need not citing security concerns;

(3) this shower, also, respectively by filter screen and anti-electric wall are set on the osculum at the software case, both can filter water, prevents from again causing security incident because of electric leakage to the user.
