detailed description

In order to fully understand the purpose, features and effects of the present invention, the idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

The invention discloses a portable shower, the main structure of which is basically the same as that of the existing portable shower, mainly including a water storage container, a heating device and a pumping power device, the cold water in the water storage container is heated by the heating device, and then The hot water is pumped through the pumping power unit so that people can shower.

In order to solve the problem that the impurity water containing more silt affects the life of the pumping power device of the existing portable shower, the main principle of the present invention is:

1. Add a water filter device on the basis of the existing portable shower, which is arranged on the water source passage of the pumping power device. The water source passage of the so-called pumping power device of the present invention refers to the water that enters the pumping power device and flows through. The purpose of the channel is to filter out impurities such as sediment in the water of the pumping power unit to protect the pumping power unit.

2. After research by the applicant, it is found that general filter devices may not be able to completely remove impurities in the water, and may also fail after a period of filtration. Once the failure is not handled in time, it will still cause damage to the pumping power device and directly affect its life. In order to further improve the service life of the pumping power device, the present invention adds a sewage channel under the water source of the pumping power device. When impurities or filtering devices fail, impurities will be deposited in the sewage channel under the action of gravity because the channel is located under the water source of the pumping power unit. The so-called lower part of the water source of the pumping power device in the present invention refers to the lower part of the passage through which the water supplied to the pumping power device flows, so as to facilitate the collection of impurities deposited by gravity. At the same time, the present invention arranges the water inlet pipe of the pumping power device horizontally on the water source channel filtered by the water filter device, so that impurities will not deposit into the pumping power device and affect its service life. And, the sewage plug seals the sewage passage, and the water in the sewage passage will be in a relatively static state, so the water containing impurities will not be extracted when the water pumping power device pumps water.

The water inlet pipe of the so-called pumping power device of the present invention is arranged horizontally on the water source channel after being filtered by the water filter device, including the horizontal arrangement in Fig. Not shown in ), so that impurities such as sediment enter the sewage channel downwards with gravity, and will not deposit into the water inlet pipe of the pumping power device. At the same time, it should be noted that the horizontal setting of the water inlet pipe of the pumping power device of the present invention is to prevent impurities such as sediment from entering the pumping power device under the action of gravity, so the water inlet pipe of the pumping power device and the horizontal plane have a slight gap between them. The degradation solution with an obliquely downward included angle is also within the protection scope of the present invention. In addition, it should be noted that the water inlet pipes of the pumping power devices in Embodiments 1-7 of the present invention are all horizontal straight pipes, and the inlet section connected to the water source passage can also be horizontal or oblique so that impurities such as silt cannot Entering this section, various shapes such as an upwardly curved arc of the part connected to the pumping power device behind are all equivalent change protection scopes of the present invention.

Therefore, the present invention reduces the impurities in the water through the filter device, and further collects the impurities deposited by gravity through the setting of the sewage channel and the sewage plug. In addition, the present invention arranges the water inlet pipe of the pumping power device horizontally to further reduce impurities. The probability of entering the pumping power device, thus solving the problems of the existing technology, greatly improving the service life of the pumping power device, especially the low-power low-voltage DC brushless water pump, which has its unique low noise and low power consumption , high security, high reliability and other advantages, are widely used. In addition, since the water filtering device is added in the present invention, the extracted water is cleaner and more hygienic, which is of course more beneficial to people's health.

Below are several specific embodiments based on the above principles, to further illustrate the conception of the present invention, specific structures and the technical effects produced:

Example 1

As shown in FIG. 1 , this embodiment discloses a portable shower, which includes a water storage container 1 , a heating device (not shown in the figure) and a pumping power device 61 .

Wherein, the water storage container 1 is a cylindrical or square barrel-shaped water tank. It should be noted that the water storage container 1 of the present invention can also be parts of other shapes and structures, as long as it can facilitate water storage and heating, it is within the equivalent protection scope of the present invention.

Wherein, the heating device may be a heating structure such as a heating plate arranged at the bottom. It should be noted that the heating device of the present invention includes but is not limited to a structure of a heating plate, as long as it can conveniently heat water, it is within the scope of equivalent protection of the present invention.

Among them, in consideration of low noise, low power consumption, high safety, high reliability, etc., the pumping power device 61 is preferably a low-voltage DC brushless water pump, especially a low-power low-voltage DC brushless water pump, such as a 24V/36V DC brushless water pump. Brush water pump, low voltage, safe and reliable. Similarly, it should be noted that the pumping power device 61 of the present invention can also be other equally efficient pumping power devices, as long as the device that can extract hot water for showering is within the equivalent protection scope of the present invention.

In order to filter the water source of the pumping power device, a water filtering device is arranged on the water source passage of the pumping power device in this embodiment, and the water filtering device includes a filter screen 21 and a water outlet funnel 22, and the filter screen 21 is installed at the bottom of the water storage container 1 , the water outlet funnel 2 is installed below the filter screen 21 to collect water filtered through the filter screen.

In order to further reduce the impurities entering the pumping power unit 61, a water outlet at the bottom of the water outlet funnel 22 is connected with a shunt tee pipe 3, and the water inlet above the shunt tee pipe 3 communicates with the water outlet at the bottom of the water outlet funnel 22, and the sewage channel 4 communicate with the water outlet below the diversion tee pipe 3 to collect impurities deposited by gravity, the water inlet pipe 62 of the pumping power device 61 communicates with the water outlet on the side of the diversion tee pipe 3, and the openable sewage plug 5 is arranged on the water outlet channel of the sewage drainage channel 4 to close the sewage drainage channel 4 .

Wherein, the sewage channel 4 is a short straight sedimentation sewage pipe or a long curved sedimentation sewage pipe. Of course, in order to achieve better impurity collection effect and convenience of use, this embodiment prefers long and curved sedimentation sewage pipes, because the pipe length can collect relatively large space, and the length of the pipe is relatively large for the user during sewage discharge. There is an advantage in choice. The short straight and long bends in this example are relative terms: the so-called short straight sediment drain pipe is a straight pipe that can extend vertically from the bottom of the portable shower, because it is relatively straight from the side wall of the portable shower. As far as the extension distance is short, this method is to directly discharge from the bottom of the portable shower; the so-called long curved sedimentation sewage pipe is the shape of the sewage channel 4 shown in the figure, and it is probably in an L shape. It may be longer than the length directly protruding from the bottom. The so-called bend is because the collected sediment is drained from the side wall of the portable shower, which can not only collect the precipitated impurities, but also facilitate the discharge from the portable shower. It can be drained next to the device without dirtying the entire floor.

At the same time, it should be noted that the so-called long and curved sedimentation sewage pipe can be drained from the side wall of the portable shower, including directly protruding out, and also including hiding it inside the portable shower when not in use, and taking it out for sewage discharge when in use, etc. Situation, these are protection scope of the present invention, needn't repeat one by one.

It should be noted that the present invention only draws the long and curved sedimentation sewage pipe, which does not represent a limitation to this example. This embodiment also includes a short straight pipe, that is, a sedimentation sewage pipe arranged vertically.

Wherein, the openable sewage plug 5 is arranged on the outlet channel of the sewage channel 4 to close the sewage channel 4, specifically: the sewage plug 5 is sealed on the short straight sedimentation sewage pipe or the long curved sedimentation sewage pipe outlet end of the pipe. The so-called openable means that the sewage plug 5 is in a closed state under normal conditions, so that the water in the sewage channel 4 will be in a relatively static state, so that the water containing impurities will not be removed when the pumping power unit 61 pumps water. Take out, when needing to get rid of the dirty water that contains impurity in the sewage channel 4, just can open it and get rid of dirty water.

Wherein, the filter screen 21 is made of stainless steel, plastic or gauze, and is the main filter component in this embodiment. In order to ensure the filtering effect, the aperture of the filter screen 21 in this embodiment is preferably less than or equal to 2 mm.

Wherein, in order to prevent that the junction between the edge of the filter screen 21 and the bottom is not tight enough, and impurities directly enter the water outlet funnel 22 from the junction, the filter screen 21 is installed and buckled in the U-shaped assembly recess connected to the bottom of the water storage container 1. in the slot. As shown in Figure 1, the U-shaped assembly groove is the part in contact with the edge of the filter screen 21 in the figure, which not only plays the role of installing the filter screen 21, but also prevents water from leaking from the edge joint of the filter screen 21. The water is just intercepted by the U-shaped assembly groove.

In this embodiment, the impurities in the water are filtered through the filter screen 21, and the filtered water is collected in the outlet funnel 22. If there are impurities such as sediment, they will reach the sewage channel 4 through the diversion tee pipe 3 under the action of gravity. The water inlet pipe 62 of the power unit 61 communicates with the water outlet on the side of the diversion tee pipe 3, which is equivalent to that the water inlet pipe of the pumping power unit is horizontally arranged on the water source path filtered by the filter screen 21, so that impurities such as silt No deposits will enter the pumping power device and affect its service life.

Simultaneously, present embodiment has had blowdown channel 4, just can regularly or irregularly clean up the waste water in the pipeline, also can when pumping power unit 61 does not work, removes the old water in the water storage container 1, avoids pumping power unit 61 long-term Soaking causes corrosion to its components, and can effectively prevent the generation of dirt and bacteria in old water, prolong the service life of the pumping power device 61 and improve the cleanliness of water quality.

Of course, the present invention preferably can wash and reuse the filter cotton repeatedly, which not only has low cost, but also has a good filtering effect. It should be noted that this embodiment includes but is not limited to the above four materials, and filter element structures made of other filter materials are also within the protection scope of the present invention.

Compared with Embodiment 1, the filtering effect of the filtering device of this embodiment is further improved due to the addition of fine filter cores 23, which will further help to improve the problem of shortening the service life of the pumping power unit 61 due to impurities such as silt.
