Description

An improved iron spray pump body Technical Field

[0001] This utility model relates to the field of liquid pump technology, and more specifically to an improved iron spray water pump body. Background Technology

[0002] For example, Chinese Patent No. CN 211320977U discloses a detachable power supply electric iron. The main body of the iron is equipped with a spray head, a water tank, and a water pump body. The water outlet of the spray head faces outward, and the water tank, water pump body, and spray head are connected in sequence through a water supply pipe. The main body of the iron is also equipped with a water supply switch group for controlling the operation of the water pump body. Pressing the water supply switch group can start the water pump body, so that the water in the water tank can be sprayed out through the spray head.

[0003] As shown in Figure 1, existing spray pumps of this type include a pump body 10 and a piston assembly. The pump body 10 contains a water storage chamber 100, and has an inlet pipe 11 and an outlet pipe 12 that communicate with the water storage chamber 100. A seal 13 is installed on the inlet pipe 11. This seal 13 opens when the pump body is pumping water, allowing the inlet pipe to communicate with the water storage chamber. When the pump body is spraying water, it seals the inlet pipe 11, allowing water from the water storage chamber 100 to be sprayed out through the outlet pipe 12. However, since the water added to the iron's water tank is usually tap water, which contains scale and other impurities, when there is water in the pump body and the spray pump is not used for a long time, the remaining impurities after the water evaporates can easily cause the seal to stick to the inlet pipe, resulting in blockage of the inlet pipe. Therefore, we provide an improved iron spray pump. Utility Model Content

[0004] This utility model provides an improved iron spray water pump body, the main purpose of which is to overcome the shortcomings of existing spray water pump bodies. When there is water in the spray water pump body and the spray water pump body is not used for a long time, the impurities left after the water evaporates can easily cause the seal to stick to the water inlet pipe, resulting in blockage of the water inlet pipe.

[0005] The present invention adopts the following technical solution:

[0006] An improved iron spray water pump body includes a pump body with a water storage chamber inside. The pump body is provided with an inlet pipe and an outlet pipe that are respectively connected to the water storage chamber. A sealing element is provided between the inlet pipe and the water storage chamber. The pump body is also provided with an elastic body. Under the elastic force of the elastic body, the sealing element does not contact the side wall of the inlet pipe.

[0007] Specifically, one end of the water inlet pipe that connects to the water storage chamber forms an enlarged groove, and the sealing element is installed in the enlarged groove.

[0008] Furthermore, an elastomer mounting groove is formed inside the water inlet pipe at the bottom of the aforementioned enlarged groove. The elastomer is installed in the elastomer mounting groove, and the seal is supported on the top surface of the elastomer. The seal does not contact the bottom surface of the enlarged groove.

[0009] Furthermore, an inverted conical surface is formed at the bottom of the enlarged groove, and there is a gap between the seal and the inverted conical surface.

[0010] Furthermore, the improved iron spray pump body of this utility model also includes a piston assembly, which includes a piston, a piston rod, and a pump body spring. The piston is installed inside the water storage chamber. The lower end of the piston rod is connected to the piston, and the upper end extends out of the pump body. The pump body spring is installed inside the water storage chamber. The upper end of the pump body spring abuts against the lower end of the piston, and the lower end abuts against the bottom surface of the water storage chamber.

[0011] Preferably, the sealing element is a steel ball, silicone, or rubber.

[0012] Preferably, the elastomer is a spring, silicone, or rubber.

[0013] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0014] 1. The water pump body of this utility model incorporates an elastic body below the seal, preventing contact between the seal and the side wall of the inlet pipe. When the pump body sprays water, the elastic body can be compressed by the seal under external force, causing the seal to seal the side wall of the inlet pipe and thus not affecting the water spraying function of the iron's water pump body. Therefore, the added elastic body of this utility model can prevent the seal from sticking to the side wall of the inlet pipe and causing blockage in the inlet pipe when there is water inside the pump body and it is not used for a long time.

[0015] 2. The bottom of the expanded groove of the water pump body of this utility model forms an inverted conical surface. When the sealing element is a steel ball, when the pump body is not working, the sealing element can fall accurately into the top surface of the elastic element under its own weight, ensuring that it does not contact the side wall of the inlet pipe.

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0021] An improved iron spray pump body, referring to Figures 2 and 3, includes a pump body 10 and a piston assembly. The pump body 10 has a water storage chamber 100 inside. To facilitate the movement of the piston assembly, the water storage chamber 100 preferably has a cylindrical structure.

[0022] Referring to Figures 3 and 4, the piston assembly includes a piston 21, a piston rod 22, and a pump body spring 23. The piston 21 is installed inside the water storage chamber 100, with its sidewalls tightly against the inner wall of the chamber. The lower end of the piston rod 22 is connected to the piston 21, and its upper end extends outside the pump body 10. The pump body spring 23 is installed inside the water storage chamber 100, with its upper end abutting against the lower end of the piston 22 and its lower end abutting against the bottom surface of the water storage chamber 100.

[0023] Referring to Figures 3 and 4, the pump body 10 is provided with an inlet pipe 11 and an outlet pipe 12, which are respectively connected to the water storage chamber 100. Preferably, the inlet pipe 11 is located at the bottom of the pump body 10, opposite to the piston; while the outlet pipe 12 is located on the side of the pump body 10. One end of the inlet pipe 11 that is connected to the water storage chamber 100 forms an enlarged groove 110, and a sealing element 13 is installed in the enlarged groove 110. In this embodiment, the sealing element 13 is a steel ball.

[0024] Referring to Figure 3, the bottom of the pump body spring 23 is exactly abutting the top opening of the expansion groove 110, and the bottom of the pump body spring 23 is narrowed to prevent the steel ball from leaving the expansion groove 110 when the water pump body is pumping water, so as to prevent it from playing a sealing role.

[0025] Referring to Figure 3, an elastomer mounting groove 111 is also formed inside the water inlet pipe 11 at the bottom of the enlarged groove 110. An elastomer 14 is installed in the elastomer mounting groove 111. In this embodiment, the elastomer 14 is preferably a spring. The sealing member 13 is supported on the top surface of the elastomer 14, and the sealing member 13 does not contact the bottom surface of the enlarged groove 110.

[0026] Referring to Figure 3, the expanded groove 110 is cylindrical in shape, and its inner diameter and height are both greater than the diameter of the steel ball. The bottom of the expanded groove 110 forms an inverted conical surface to allow the seal 13 to slide smoothly onto the top surface of the elastomer 14.

[0027] A push button (not shown in the figure) can be installed on the upper end of the piston rod 22. In use, the operator manually presses the push button to move the piston rod inward, pushing the piston to compress the pump body spring. When the force on the push button disappears, the piston and piston rod move outward under the elastic force. Due to the lower pressure in the water storage chamber, water flows along the inlet pipe, pushing up the seal and entering the water storage chamber. When the operator presses the push button again to move the piston rod inward, pushing the piston to compress the pump body spring, the seal, under water pressure, seals the inlet pipe opening, and water from the water storage chamber sprays out from the outlet pipe.

[0028] The sealing element of this invention is not limited to steel balls; it can also be made of silicone or rubber. Similarly, the elastomer is not limited to springs; it can also be made of silicone or rubber.

[0029] The piston rod of this invention is not limited to being pressed by a push button; it can be connected to a power mechanism such as a cylinder.

[0030] In the above embodiments, the piston rod is mounted on the upper part of the pump body, while the inlet pipe is mounted on the bottom of the pump body. Of course, in other embodiments, when the pump body is placed horizontally, the piston rod and the inlet pipe are located in the left and right directions of the pump body, respectively. Therefore, the piston rod and the inlet pipe are not limited to being mounted on the upper and lower parts of the pump body, but can be mounted axially on the pump body.

[0031] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
